Cartoon Network and its sister channel Boomerang have edited many Looney Tunes shorts, mostly for anything considered politically incorrect nowadays: racial/ethnic stereotypes, tobacco smoking, alcohol drinking, some prescription drug abuse, and suicide gags are the main targets, though some gun gags were cut for being too violent, the occasional instances of bad language have also been removed, cuts allegedly made for time constraints (mostly because some of the shorts that aired ran at PAL speed rather than NTSC), and cuts made because the short was edited either before theatrical release or when it was reissued and evidence of an original uncut print is either rare or nonexistent (as seen with such shorts as "Devil's Feud Cake", "Bugs Bunny Rides Again", "Prince Violent", and "The Crackpot Quail")
Most of the cuts made only apply to the American feeds for Cartoon Network and Boomerang, as most overseas Cartoon Network and Boomerang channels air the shorts uncut, though there have been instances where this isn't the case. Like most American channels that have aired the Warner Bros. shorts, most of the cuts made are inconsistent (a cartoon that once appeared edited on the network will appear uncut some time later -- and vice versa) and can come off as hypocritical (a cartoon with an offending scene gets cut, but the same offending scene is left in on another cartoon -- or an offending scene in a cartoon gets cut, yet a more dubious scene in the same cartoon is left in inexplicably).
Ain't That Ducky (1945)
- The scene where the Victor Moore hunter shoots his gun at Daffy's head, causing him to have the hairstyle of a stereotypical black girl, was deleted (though some primetime showings of this cartoon aired this scene intact).
Ali-Baba Bound (1940)
- Starting in late 2001 (shortly after the September 11th attacks), the scene where one of Ali Baba's men (who has a bomb strapped on his head) is revealed to be a member of the "suicide squad" was cut along with the scene of the bomber sitting next to a building.
Any Bonds Today? (1942)
- When this short aired during the ToonHeads special, "The Lost Cartoons", the part where Bugs turns into Al Jolson (complete with blackface) during the title song was censored with a page-turning scene transition.
- Despite airing edited on ToonHeads: The Lost Cartoons, this short was one of the notorious 12 Bugs Bunny cartoons that was pulled from the June Bugs 2001 marathon for containing outdated ethnic stereotypes that couldn't easily be edited out (joining "All This and Rabbit Stew", "Mississippi Hare", "Herr Meets Hare" [which ended up airing on a ToonHeads special about World War II cartoons], "Bugs Bunny Nips the Nips" [which aired in clips on the same special that "Herr Meets Hare" did], "Bushy Hare", "Which is Witch", "Horse Hare", "A Feather in His Hare", "Hiawatha's Rabbit Hunt" [which did air a few times on Cartoon Network in the early 2000s], "Frigid Hare" [which didn't air until Chuck Jones died in 2002], and "What's Cooking, Doc?" [which aired on The Bob Clampett Show]).
Aviation Vacation (1941)
Two scenes in the "Darkest Africa" scene were deleted:
- The scene where the natives pound their drums, to which one native asks another, "Uh, what do he say?" The other native says (imitating drum sound), "Uh, he say, uh, 'Boom-ditty-boom-ditty-boom-boom-boom-boom, ditty-boom-ditty-boom-ditty-boom-boom-boom-boom'.
- The scene where a native uses a blowgun on a practice target, with a second commenting "Terrible shot, Joe."
Baby Bottleneck (1946)
- On the Turner Entertainment "dubbed" version, the scene of the baby alligator delivered to the mother pig was cut to get rid of the abrupt and obvious jump to the next scene. The original version of the pig and alligator scene had a close-up shot of the mother pig telling the baby alligator "Don't touch that dial!" when it attempted to get at her teat. This was removed before its theatrical release for being too suggestive. While the actual scene was never reinstated in the cartoon, The Bob Clampett Show did show a version where one can see the abrupt and obvious jump to the next scene.
- The scene near the beginning of the cartoon, with the drunken stork at the Stork Club was deleted (barring its appearance on The Bob Clampett Show).
Baby Buggy Bunny (1954)
- The whole sequence of Finster pulling a gun on Bugs, Bugs thinking it's a toy, and Bugs getting shot in the face was cut.
Ballot Box Bunny (1951)
- The Russian Roulette ending gag was deleted with a fake iris-out after Bugs and Sam look at each other. Since 2011, this short has aired uncut in America (though it was already shown uncensored in Cartoon Network's European channel).
Barbary-Coast Bunny (1956)
- For a time on Cartoon Network and its sister channel Boomerang, the entire ending with Nasty Canasta shooting himself in the face was replaced with a repeat shot of Canasta's upset face after Bugs beats him at poker intercut with Bugs carrying his winnings in a wheelbarrow, making it seem as if Canasta got upset over Bugs taking him for everything he had in the poker game. As of 2011, the original ending has been restored on both Cartoon Network and Boomerang.
Beanstalk Bunny (1955)
- Between 2003-2010, the scene of Daffy and Bugs getting stuck in Giant Elmer's head alternated between showing the scene of Giant Elmer corking his ears and trying to smoke a cigarette to get Bugs and Daffy out of his head and having the scene edited. Since 2011, this short is now uncut.
Believe It Or Else (1939)
- The "berth of a baby" sight gag was cut because it featured two black on-board train employees.
Big House Bunny (1950)
- The entire scene of Bugs running up onto a gallows, pressing a button that lowers him like an elevator, and Sam Schultz doing the same, only to get hanged was cut.
The Big Snooze (1946)
- Bugs using sleeping pills to enter Elmer's dream was once edited with a fade to black as the taking of the pills occurs, then returning as Bugs sings "Somebody's Rockin' My Dreamboat". Since 2001 (after it aired on The Bob Clampett Show), this short has aired uncut.
Boobs in the Woods (1950)
- Cartoon Network had temporarily aired a version of this cartoon with the entire scene of Daffy disguising himself as Pocahontas removed after Porky is sentenced to be beheaded. Recent airings of this short on CN (starting when it aired in 2002 on a two-hour weekend installment of The Acme Hour) have the Pocahontas scene intact.
Book Revue (1946)
- The scene of Daffy and the wolf running into the book "Uncle Tom's Cabin" (with Daffy as the black slave woman running through the frozen river to get away from the wolf) is cut. This edit does not apply to when this short aired on The Bob Clampett Show.
Boyhood Daze (1957)
- In the jailhouse sequence, a small scene of Ralph smoking a cigarette was deleted (surprisingly, the earlier sequence of Ralph rescuing his parents from African cannibals wasn't cut like it was on ABC, Nickelodeon, and even TBS).
Brother Brat (1944)
- The scene where Baby Percy impersonates Winston Churchill after crashing into the kitchen and saying, "Of course, you know, this means war!" was removed (though, surprisingly, not the part where Baby Percy's mom uses the word "Japs").
Bugs' Bonnets (1956)
- The scenes where Elmer assumes General Douglas MacArthur's personality after he dons a general's hat with a pipe attached to it at the brim and the scene where Bugs acts like a mobster (after a mobster's fedora falls on his head) were edited to remove the short scenes of Elmer and Bugs respectively smoking from the pipe and cigar.
- The entire part where Bugs becomes a game warden who accuses Elmer of shooting out of season and before Elmer can answer, has a Pilgrim's hat fall on his head and reply that he's shooting turkeys for the first Thanksgiving dinner, after which an Indian's wig (consisting of long black hair done in braids and two feathers on top) lands on Bugs' head and Bugs begins acting like a stereotypical Native American. These two parts were later reinstated in January 2001 during the Cartoon Network Super Bowl parody special, "The Big Game: Bugs vs. Daffy" and has aired uncut since.
Bugs Bunny Rides Again (1948)
- Cartoon Network's Arabian/Middle Eastern channel cuts out the shot near the end of the interior of the Miami Express Train, which features beautiful women in swimsuits. Other Cartoon Network stations (including the one in America), however, left this scene uncut.
- Over in America, Cartoon Network and Boomerang air the version where Yosemite Sam's intro line when he enters the saloon ("Yeah, Yosemite Sam. The roughest, toughest, he-man-stuffest hombre to ever cross the Rio Grande...") ends with "And I ain't no namby-pamby" instead of "And I don't mean Mahatma Ghandi" (the original line was changed following Ghandi's assassination when this short was reissued to theaters. The "namby-pamby" version is the version that airs frequently on other TV networks besides Cartoon Network and Boomerang and is even seen on home media releases).
Ceiling Hero (1940)
- A brief sight gag involving a Chinese airliner with features resembling a stereotypical Asian face was cut.
- When this Private Snafu short aired on the Cartoon Network anthology series, ToonHeads, the scenes of Sally Lou topless (specifically, the scene of her answering the door to get the mail and leaning over the vanity to decode the letter) were cut, though not the scene of Sally Lou talking to her mother on the phone while topless (and the topless pin-ups Snafu has around his sleeping quarters weren't censored either).
Chow Hound (1951)
- Starting in March of 2001, the part where the dog (dressed as a game hunter) returns the cat (dressed as a sabre-toothed tiger) to the zoo was deleted because the mouse is depicted as an African savage.
Claws for Alarm (1954)
Two scenes were edited on pre-2002 airings:
- The scene where Sylvester uses a noose to demonstrate to Porky what could have happened to him had Sylvester not saved him was cut. This scene was also cut on Cartoon Network (pre-2002) whenever Daffy Duck's Quackbusters aired.
- The scene where a noose lowers on Porky while Porky is sleeping, Sylvester cuts the noose with a razor and Porky accuses Sylvester of attempted murder was cut.
Since 2002, the short has aired uncensored.
Confederate Honey (1940)
- Though this cartoon rarely aired (and still doesn't air much today) due to its Civil War theme and scenes featuring African-American slaves, the 1995 Turner "dubbed version" print of the cartoon which is very rarely shown on Cartoon Network, The WB, and Boomerang (and also released as a bonus feature on the Virginia City DVD release) exists with following scenes of black stereotyping removed:
- The shot of the sign reading, "Uncle Tom's Bungalows--$1.50 a Night and Up"
- All scenes featuring the black cotton pickers.
- A shot of a slave girl (called Topsy by Crimson O'Hairoil) putting the finishing touches on Crimson O'Hairoil's dress.
- The scene with the slave validating parking tickets is cropped so the viewer only sees the slave's hand.
- The scene where Elmer gives his horse to a slave valet crops out the appearance of the slave valet and is shortened to remove the part where the slave actually parks the horse.
- All three scenes of the slave waiting for Elmer to retrieve his horse.
A Coy Decoy (1941)
- Daffy singing, "I Can't Get Along Little Doggie", jumping into the book, Black Beauty, and riding out on the shoulders of a black mammy caricature was removed entirely.
The Crackpot Quail (1941)
- When this cartoon was originally released in theaters, the quail would constantly make a razzing noise in order to keep his top knot from falling down over his eyes. However, around the time the short was sold to Associated Artists Productions, the razzing noise was replaced by a whistle. The "whistle" version is the version that airs frequently on TV (including on Cartoon Network and Boomerang).
Crazy Cruise (1942)
Two scenes of ethnic stereotyping were cut:
- The entire sequence of two hunters (caricatures of director Friz Freleng and writer Michael Maltese) getting captured by African cannibals and compared like cigarettes.
- The final scene of the rabbits (one of which is Bugs Bunny himself) fighting back against a vulture (who looks like a World War II-era Japanese caricature) is cut to remove the actual shot of the vulture bearing down on the rabbits. This censored scene was shown as a clip in the ToonHeads episode about World War II cartoons.
Cross Country Detours (1940)
- The frog sight gag where one of them literally croaks by shooting himself in the head was edited to remove the actual shooting (going from "Here, we have a close-up for a frog croaking" followed by a smash cut to the notice stating that the theater management isn't responsible for the lame puns in this cartoon), making it obvious that something is missing.
Crow's Feat (1962)
- On Cartoon Network and Boomerang's Brazil channel, the entire sequence where Manuel and Jose collect corn and Elmer tricks them into picking a painted grenade was cut, mostly because the crows were singing the version of La Cucaracha that had the line "...marijuana que fumar" (similar to how "Gonzales' Tamales" was edited). In contrast, other international Cartoon Network and Boomerang feeds have aired this uncut, barring the American feed, which doesn't air this short (or "Two Crows from Tacos") at all due to the Mexican stereotyping.
Curtain Razor (1949)
- The wolf drinking a canister of gasoline was deleted (though surprisingly, the scene of the Al Jolson duck begging for his "mammy" until the Bing Crosby parrot beans him on the head with his pipe wasn't cut or had the audio muted).
Daffy Duck & Egghead (1938)
- Egghead shooting an audience member who won't sit down was removed (though similar gags in "The Ducksters" and "Rhapsody Rabbit" weren't censored).
Daffy's Inn Trouble (1961)
- The scene where Daffy tries to make a deal with Porky over being partners at the hotel (which ends with Daffy threatening to shoot Porky and ends up shooting himself with his own gun) was cut when shown on Cartoon Network prior to 2004. The short started airing uncut in 2005. However, when the Sandy Hook Elementary School shooting happened in 2012, the short had to air censored again, only this time, it was temporary. As of 2015, the short airs uncut on Boomerang.
A Day at the Zoo (1939)
- The sight gag featuring a group of camels smoking (a reference to the real-life Camel cigarettes) is spliced from this short.
Detouring America (1939)
Two scenes of ethnic stereotyping were deleted:
- A poor, black hitchhiker at the North Pole, singing "Carry Me Back to Ol' Virginny", and an Eskimo obliges by literally carrying the poor, black man all the way to the Virginia state line.
- Although the Native American segment is not removed entirely (there had been rumors that it was, but those were disproven), only one scene from the segment is cut: an Indian mother dealing with the dopey, oversized, adult son she's carrying on her papoose.
Devil's Feud Cake (1963)
- In the original version shown in theaters, the Devil greets Sam with "Well, who in Hell are you?" Like most television prints, the line was changed to "What the devil is your name?"
Dog Collared (1950)
- The sequence where Porky disguises himself in various costumes was removed entirely for a while due to the parts where Porky dons both an Indian and Chinaman disguise (and the dog acting as a Chinaman as well). It then aired with most of the sequence intact, save for Porky dressed as an Indian and a Chinaman. Since 2010, this short has aired uncensored.
Doggone Cats (1947)
- The part where a trash can lid falls on Wellington's head, causing him to impersonate a Chinaman, was cut.
Drip-Along Daffy (1951)
- Porky's last line, "Lucky for him, it is a one-horse town" (after Daffy is shown as the town's new sanitation officer) was deleted. It's been debated online whether this was cut to get rid of the scatological implications or because of time constraints (since the short was running at PAL speed rather than NTSC). As of 2019, Boomerang airs this short uncut.
The cuts here were made when the short went from being part of the Daffy Duck Thanks-for-Giving TV special to being reformatted as its own short, and are also the same cuts made when this short aired on ABC, Nickelodeon, The WB, and even most home media releases (though Cartoon Network's and Boomerang's versions actually leave in the "That's All, Folks" end card where Marvin tells the audience not to worry about the Earth being annihilated because it's just a cartoon):
- Dodgers telling Marvin he's under arrest was cut.
- Dodgers referring to several locations in New York City that he’ll miss after Marvin tells him of his plan to blow up the Earth was deleted.
- Porky using a straitjacket gun to capture Marvin the Martian was cut.
- The real ending where Marvin (still wrapped in the straitjacket) aims his missile at Earth and fires it, then tells the viewers that the missile will take three days to reach Earth, giving everyone time to get their affairs in order before everyone gets annihilated was removed.
Feather Dusted (1955)
- The "Fort Pale-Face" sequence was cut, going from the "Cops and Robbers" sequence to the pirate sequence.
The Fifth-Column Mouse (1943)
- The part in which the gray mouse refuses the cat's deal of all the cheese that the mouse wants in exchange for leading the mice population to appease the cat, but the cat forced him to accept the deal, followed by, "NOW, GET GOING!" was deleted, because it showed the cat briefly putting on a mock Japanese face and the gray mouse giving the Hitler salute.
The Fighting 69½th (1941)
- The part where, after the black ants head back to the trenches with a hot dog, a blackfaced ant with white lips and a Rochester-esque voice, goes above the trenches to get mustard was cut.
For Scent-imental Reasons (1949)
Prior to 2003, this short aired uncut. From 2003 to 2010, the following edits (which, coincidentally, were similar to the edits made when this short aired on ABC) were made:
- The scene where Penelope locks herself in the glass case and Pepe lures her out with a faked suicide was removed.
- Pepe stating that Penelope's "committing suicide to prove her love for him", but nevertheless must prevent it, was removed (a similar scene in 1961's "A Scent of the Matterhorn" was not edited when aired on Cartoon Network and Boomerang).
As of 2011, the short has returned to airing uncut.
Fowl Weather (1953)
- Hector imagining Granny shooting him dead after discovering that Tweety's missing and Sylvester hasn't eaten him was removed (though the earlier scene of Granny mimicking her shooting Hector with her umbrella wasn't cut). As of 2013, this short airs unedited on Boomerang.
Freddy the Freshman (1932)
- The shot of the Jewish bird cheerleaders chanting and a mincing homosexual rooster strutting in to cheer as well was cut when this short aired on the compilation show Late Night Black and White.
Fresh Hare (1942)
- The end gag where Bugs breaks out into singing "I Wish I Was in Dixie" after Elmer tells him that he's entitled to one last wish and the entire scene inexplicably turns into a blackface performance of "Camptown Races" was cut, ending with a dissolve to the dubbed version end card just as Bugs sings "I wish I was in Dixie/Hurray, hurray..."
Frigid Hare (1949)
Despite being one of the 12 Bugs Bunny cartoons that didn't air during the 2001 June Bugs that advertised that every Bugs Bunny cartoon ever made would air, this short eventually aired on Cartoon Network and Boomerang with some minor edits:
- Bugs calling the Inuit hunter an "Eskimo pie-head" was cut (though this scene was initially left uncut when the short first aired on a special Looney Tunes Show compilation dedicated to Chuck Jones following his death in 2002).
- Bugs' final line about how, since the polar days are six months long, he won't have to go back to work until July of 1953, was cut for being outdated.
From A to Z-Z-Z-Z (1954)
- The scene in Ralph's Western fantasy where he's shooting at American Indians attacking him was cut.
From Hand to Mouse (1944)
- The scene where the mouse disguises himself as a Zulu native was cut, although the part where the mouse disguises himself as an Indian chief was not cut.
A Gander at Mother Goose (1940)
- The parody of Little Hiawatha where Hiawatha shoots an arrow in the air and gets confronted by an angry eagle who got hit was cut.
Gift Wrapped (1952)
- Both Cartoon Network and Boomerang (along with the former WB network) left the "dynamite in the cage" sequence intact that was cut on ABC, but used to edit out the entire Hopalong Cassidy sequence (because of the American Indian stereotyping and gunfire), fading out into the train sequence instead. Despite being cut from the cartoon proper, the clip show cartoon "Tweet Dreams" was shown on Cartoon Network with the scene from "Gift Wrapped" uncut while Boomerang currently airs "Gift Wrapped" uncensored.
Ghost Wanted (1940)
- Airings on Cartoon Network and Boomerang in the United States cut a short scene of Big Ghost suggesting Little Ghost smoking cigarettes and a shot of Old Ghoul Cigarettes, although the scene where the Big Ghost smokes the cigarette and blows out a puff of smoke that reads "BOO" is left in.
Gonzales' Tamales (1957)
- Most international Cartoon Network and Boomerang feeds cut Sylvester's line, "I'll getcha if I have to eat every one of these things" as he's going through the box of hot peppers in search of Speedy Gonzales. Contrast with Cartoon Network America, which aired the short uncut once, but pulled the cartoon due to complaints about the Speedy Gonzales series being offensive to Mexicans.
- Cartoon Network's Latin America channel cuts the part where Sylvester tries and fails at getting Speedy with a hand grenade (for both the use of explosives and the song La Cucharacha being sung, which includes a reference to marijuana) and Sylvester's "I'll getcha if I have to eat every one of these things" line.
Goofy Groceries (1941)
Barring its appearance on The Bob Clampett Show, three scenes featuring black stereotyping were cut:
- A scene of black children diving and swimming in a sink
- A short scene of a black boy rushing into a house and hanging a "Quarantine: Measles" sign during the gorilla attack
- The end where the stick of dynamite in Jack Bunny's hands explodes and turns him blackfaced, where he comments, "My, oh my! Tattletale gray!" a la Rochester from The Jack Benny Show.
Goopy Geer (1932)
- When Cartoon Network aired this as part of their late Sunday night compilation show, Late Night Black and White, the part where the gorilla says, "Yessir! Yessir" as he's walking through the restaurant was cut.
Hare Ribbin' (1944)
- The popular ending where the Russian Dog, distraught over Bugs' "death", wishes he were dead too, and Bugs obliges by giving the dog a gun so he can shoot himself in the head was cut, barring its appearance on The Bob Clampett Show and on two consecutive New Years' Day Looney Tunes marathons (one in 2009 and another in 2010). The Bob Clampett Show also made mention of the "director's cut" ending (where Bugs shoots the dog through the mouth) which has never aired on television, but has been released on some home media prints.
Hare Splitter (1948)
- When Cartoon Network aired this cartoon as part of the infamous 2001 June Bugs special (the one that banned 12 Bugs Bunny cartoons for having racial and ethnic stereotypes in them), a rather innocuous part (possibly for time reasons) where, after the novelty-carrot-induced explosive kiss between Bugs and Daisy Lou, Daisy Lou responds with "What a man!" while Bugs responds with "What a woman!" was edited out and immediately went to the scene of them happily jumping around the room before the iris-out. On Cartoon Network's other installment shows (such as The Looney Tunes Show and Bugs and Daffy) and current airings on Boomerang, the "What a man!"/"What a woman!" scene was left intact.
The Hasty Hare (1952)
- For reasons unknown (possibly time constraints), a rather innocuous part is cut where after the Friz Freleng-esque astronomer sees Bugs' spaceship with the stars, planets, and moons attached to it, he writes a note and leaves, then it cuts to a close-up of the note and it reads, "I resign! When I begin to see things like this, it's time to take up turkey farming." The CN and Boomerang version (American feed; international feeds have this uncut) just has the shot of the astronomer staring in shock after seeing the spaceship, then it cuts to him walking out of the observatory before being questioned by Bugs.
The Heckling Hare (1941)
- Though neither Cartoon Network nor Boomerang aired the original ending where Bugs and Willoughby fall down another cliff, with Bugs yelling, "Hold on your hats, folks! Here we go again!" (an ending that has evidence that it was planned, but actual footage of it may or may not have been made), both networks (along with TBS and TNT) cut out Willoughby saying "Yeah!" as the cartoon ends to cover up the fact that the cartoon has a missing ending.
Here Today, Gone Tamale (1959)
- In the rare times this short aired (since neither Cartoon Network nor Boomerang air Speedy Gonzales cartoons due to complaints of the character being a Mexican stereotype), the scene of Fernando handing his sombrero to his friend and putting a gun to his head in despair, after the mice are barred from getting on the cheese boat by Sylvester, was cut.
Holiday for Shoestrings (1946)
A scene featuring two stereotypical East Indians was cut on the American version of Cartoon Network and Boomerang (both edits come off as odd, since there have been countless scenes featuring East Indian-looking snake charmers uncut in other shorts and the Porky Pig short "Porky in Egypt" had a scene of an Egyptian fakir who sat on a bed of nails and did a fire-eating stunt):
- A fakir elf using the back of a shoe-sole as a bed of nails
- A snake-charmer elf playing the pungi while the boot's shoelace rises like a charmed snake and laces itself neatly.
Horton Hatches the Egg (1942)
- The scene of the Peter Lorre fish saying, "Well, now I've seen everything" after seeing Horton on the boat cut off after "Well, now I've seen everything" to remove the fish taking a gun out and blowing his brains out (this edit doesn't apply to the Bob Clampett Show version of this short).
I Like Mountain Music (1933)
- When this aired on Late Night Black & White, the short scene of Zulu natives flapping their oversized lips in tune with the music was cut. The cut also appeared when Cartoon Network aired a redrawn colorized version of the short as part of the anthology series, ToonHeads (on a rerun of the episode "Midnight at the Bookstore" that got rid of the Frank Tashlin cartoon, "You're an Education", and replaced it with "I Like Mountain Music").
I Taw a Putty Tat (1948)
- The scene of Sylvester posing as a Swedish maid so he can get Tweety, only to grab a stick of dynamite and end up in blackface and sounding like Rochester from The Jack Benny Show ("Uh-oh. Back to the kitchen. I smell something burning") was cut.
I Was a Teenage Thumb (1963)
- Unlike the 1998 ABC version and the Nickelodeon version, the American versions of Cartoon Network and Boomerang did not cut out the "you ass" in the line, "Morty, you ass! This fish is full of people." Rather, both channels deleted the scene containing the line. The "you ass" line does air uncut on Cartoon Network and Boomerang channels outside of America.
Injun Trouble (1938)
- Outside of airings on The Bob Clampett Show, the sequence where Injun Joe chops a Statue of Liberty from a tree was shortened so that way we only see Injun Joe and Porky come down the other side.
Into Your Dance (1935)
- An early scene with a quartet of blackface minstrels singing "Go Into Your Dance" as everyone enters the show was removed.
An Itch in Time (1943)
- The end where the cat says, "Well, now I've seen everything" and shoots himself after seeing the hobo flea carry Elmer and the dog off on a blue plate special was cut to remove the cat shooting himself (this edit does not apply to the version featured on The Bob Clampett Show)
Jeepers Creepers (1939)
- On Cartoon Network's American feed (barring its appearance on Late Night Black and White and The Bob Clampett Show), the end where the ghost gets blasted in the face with exhaust from Porky's squad car and ends up in blackface was cut with a quick black-out after Porky's car blows exhaust in the ghost's face, even though the version of this short that Cartoon Network America aired was a redrawn version where the ghost was yellow and opaque and a redrawn version exists where the blackface scene is left in, only the blackface was recolored as purple to make it less offensive. In contrast, overseas Cartoon Network channels have aired a computer colorized version, which leaves the offending scene intact, but, curiously, doesn't colorize the blackface ghost (except for the tongue).
Knight-Mare Hare (1955)
- The short scenes of Bugs Bunny tying a blindfold over his eyes as the knight charges into him and the brief scene of Bugs still standing as the knight charges into him before Bugs sticks his foot out and makes the horse trip and the knight fly off his horse and into the tower were cut because Bugs had a lit cigarette in his mouth on both occasions.
The Last Hungry Cat (1961)
- Back in the early 2000s, the only scene cut from this short was the part where, after Sylvester falls through the groove through the floor he made while pacing, we then see Sylvester nervously chain-smoking and downing two cups of coffee. In the mid-2000s, the cartoon returned with an additional cut: the part where Sylvester runs to the bathroom, takes a bottle of pills from the medicine cabinet, and swallows most of them (while rubbing the rest under his arms and on his head). Boomerang currently airs this short with both scenes of drug abuse censored.
Life with Feathers (1945)
- The part where the lovebird thinks of different ways to commit suicide (shown as crudely drawn pencil sketches of the bird shooting himself, jumping off a building, laying down on some active train tracks, and letting a cat eat him) after his wife has thrown him out is cut (American feed only).
Lights Fantastic (1942)
- The scene featuring Chinese people frantically reading Chinese print on a movie marquee and speaking in Chinese very fast is cut. The previous scene, showing people boarding a rickshaw tour bus, was also edited, but instead of being cut, it was cropped so the Chinese rickshaw drivers are barely shown. However, the scene with the Dr. I.C. Spots eye test where the announcer says, "If you can read this, you are Chinese" followed by a shot of Chinese lettering wasn't cut.
- During the end scene with the Egyptian cigarette ad, the last frame of the billboard where it shows a cheesecake picture of a redheaded woman posing in a green swimsuit is cut. While it may seem like an innocuous cut done due to time constraints, frame-precise pausing reveals that the woman's green swimsuit is translucent enough to reveal her naked body (Cartoon Network actually aired this scene uncut -- though the scenes featuring Chinese stereotypes were still edited -- on a late-night showing of The Acme Hour. The edited version was often seen on daytime and evening versions of compilation shows like Bugs and Daffy, The Looney Tunes Show, and Toonheads)
Martian Through Georgia (1962)
- The scene of the Martian running through an abstract hell of people yelling and screaming, holding his ears to block out the noise, and tearfully putting his space gun to his head, with the narrator encouraging him to commit suicide if he truly feels that no one loves him was cut. However, unlike the versions shown on ABC, Nickelodeon, and The WB (which used a fake black-out to eliminate the entire scene), Cartoon Network and Boomerang left in the Martian running through the chaos of people panicking and holding his ears, but paused on the shot of the Martian fearfully wincing to cover up the offending scene of the Martian about to blow his brains out, and the narrator's line, "If you're a monster, what are you going to do? Commit suicide? Why not? If nobody loves you..." was cut down to "If you're a monster, what are you going to do? Nobody loves you..."
Meet John Doughboy (1941)
- The entire sequence of the fast moving jeep driving around a battlefield and stopping to reveal Rochester as the driver and Jack Benny in the back was cut on the rare times it aired outside of The Bob Clampett Show.
Mexicali Shmoes (1959)
- In the few times Cartoon Network and Boomerang have aired this short, the end gag where Jose captures Slowpoke Rodriguez was edited to remove the part where Slowpoke shoots Jose in the face with a gun just as Manuel tries to warn him that Slowpoke Rodriguez keeps a gun on him.
Mexican Joyride (1947)
- Much like the Speedy Gonzales cartoons, this rarely aired on the American versions of Cartoon Network and Boomerang because of the Mexican stereotypes. However, when this short aired on The Looney Tunes Show in the early-to-mid-2000s on Cartoon Network, all scenes of the bull holding a gun to his head to commit suicide (after Daffy tricks him into believing he gambled away all his money and that there's no way out except suicide) are cut.
Milk and Money (1936)
- A small scene of black stable hands leading the horses to the start of the race was removed.
The Mouse-Merized Cat (1946)
- The scene of Babbit hypnotizing Catstello to act like Rochester receiving a telephone call from Jack Benny was cut (though there was a time in the late 2000s when Cartoon Network aired this scene uncensored. Whether this was a mistake or a sign that their censors were lightening up on allowing objectionable content isn't known).
The Old Grey Hare (1944)
- Excluding appearances on the first "June Bugs" marathon and The Bob Clampett Show, Cartoon Network and Boomerang (in the United States, Canada, and Latin America) airs the USA Turner dubbed version which has the original shaking end card (after old Bugs gives old Elmer a stick of dynamite after burying him alive) replaced by the 1947-48 Merrie Melodies card which doesn't shake (though the explosion sound is still heard).
Patient Porky (1940)
- Much like Nickelodeon's version, this cartoon was cut to remove all the scene featuring Rochester, the black elevator operator.
Peck Up Your Troubles (1945)
- The part where Sylvester holds the gun to his head and attempts to shoot himself after the "angel" woodpecker gives him the gun was cut to remove the short scene where the gun goes off and Sylvester ducks out of the way before blasting the woodpecker in his rear end (American feeds only; international feeds are uncut).
Pied Piper Porky (1939)
- The Rochester mouse's line referring to Pied Piper Porky's flute, "This thing's no good, boss! Full of holes!", is edited to mute out "boss".
Plane Daffy (1944)
- The ending when Hitler's henchmen (Hermann Goerring and Josef Goebbles) agree with the "military secret" that Hitler is a stinker cuts to Daffy saying "They lose more darn Nutzis that way!" to remove the part where the henchmen shoot themselves in the head.
- Despite editing that scene from the short proper, Cartoon Network once showed a clip of the offending part on the animation history anthology show ToonHeads, on an episode centered on World War II cartoons. It was featured in a montage near the end, where narrator Leslie Fram explains that a lot of the outdated references and outrageously offensive stereotypes of Germans, Italians, and Japanese people have prevented a lot of wartime cartoons from being shown on modern American TV and, in some cases, distributed on home video (and those that do are usually edited to remove them, especially on television airings).
Porky the Fireman (1938)
- The part where a panicky white man screaming "Help! Help! Get the net ready!" as he falls comes out of a dark cloud and becomes a lazy black man was cut to remove the latter part of that scene (yet the scene of Porky dumping smoke into a fishbowl and the fish inside becoming blackfaced was never edited on Cartoon Network's version).
Porky's Baseball Broadcast (1940)
- The scene where Porky mentions "the scalpers" having a big day, followed by a scene featuring American Indians chasing after baseball patrons with tomahawks was cut, beginning in 2001 and has been that way on the channel (and Boomerang) ever since. Prior to that, the "scalpers" scene was uncut on both the original black and white version and the computer-colorized version.
Porky's Hero Agency (1937)
- The scene of the Gorgan's guard telling Porky that he's next to be turned to stone followed by Porky picturing himself as a piggy bank as the guard advances on him threateningly, is cut (barring its appearance on The Bob Clampett Show), most likely because the Gorgan's guard looks as if he's in blackface.
Porky's Prize Pony (1941)
- A very brief shot of the black stablehands leading horses out before the start of the races was cut.
Porky's Road Race (1937)
- The Stepin Fetchit caricature slowly leaving the start line was deleted in the computer colorized version, though some airings of this short were uncut.
Prince Violent (1961)
- Aired as "Prince Varmint" due to Cartoon Network acquiring the free-to-air TV version that aired on The Merrie Melodies Show with a newly-made title card that has Bugs in Viking garb sitting on the side of a castle rather than the original title card, which has the title on the sail of a Viking ship.
The Queen Was in the Parlor (1932)
- When this short aired on Late Night Black and White, the scene of the knights saying, "The Queen?" in succession was cut to remove the shot of a Jewish knight saying, "The Queen? The Queen!"
Rebel Rabbit (1949)
- The scene during the montage of Bugs destroying America where Bugs trades Manhattan back to the Native Americans and is shown walking through it wearing a feathered headband and smoking a peace pipe before asiding to the audience, "They wouldn't take it back unless I t'rew in a set of dishes." was cut post-2001. Prior to that, Cartoon Network did air it uncut during an after-midnight showing of Bugs and Daffy.
The Rebel Without Claws (1961)
- In an inverse to the version shown on The WB (where the Confederate general's "Damn Yankees" had "damn" removed and Tweety's "I tawt I taw a damn Yankee tat!" was completely cut), Cartoon Network's version faded to black just before the Confederate general mutters, "Damn Yankees!" and left in Tweety's line, "I tawt I taw a damn Yankee tat!", but cut the "damn" out of it, making for a mildly obvious audio edit.
Roman Legion-Hare (1955)
- For reasons unknown (possibly time constraints), Cartoon Network's and Boomerang's airing cuts out Bugs's line near the end of the cartoon (after Nero and Sam are chased to the top of the column by the lions), "Well, like the Romans say, E. Pluribus Uranium."
Rookie Revue (1941)
- The shot of the Suicide Squad (a trio of depressed soldiers) unhappily eating hash from a bowl (along with the narrator's line at the end of that shot: "And so, their appetites appeased, the Army is ready to carry out the orders of the day", which was cut for continuity reasons) is cut on the rare times Cartoon Network and its sister channel Boomerang have aired this cartoon.
Scaredy Cat (1948)
Cartoon Network and Boomerang (American feed only) have aired two versions of this short, each with violent parts edited:
- One version has the Blue Ribbon Merrie Melodies title card and cuts the scenes where Sylvester threatens to shoot himself with the gun from Porky's drawer if Porky does not let him stay to protect him from the mice and the scene where Porky bends over to pick up a scared Sylvester and nearly misses being shot by a mouse in a black hood.
- A rarely shown 1998 dubbed version, with the original opening and credits, which first aired on a 4:00 am showing of the Cartoon Network compilation show Bugs and Daffy in 2003 and aired again on a New Year's Day marathon of Looney Tunes cartoons on January 1, 2010, has the original title cards and credits and reinstates the scene where Porky bends over to pick up a scared Sylvester and nearly misses getting shot by a mouse in a black hood, but still edits the scene where Sylvester withdraws a pistol from a drawer and threatens to kill himself with it and fights with Porky over the gun. In contrast to the usual "dissolve-edit" version that aired frequently on Cartoon Network, the newly edited version cuts from Porky asking Sylvester to leave his bedroom to Sylvester crying and Porky chastising him for being a crybaby before relenting, and crops the shot of Porky chastising Sylvester for crying so the gun behind Porky's back is never shown. As of 2011, this newly-edited version is the version that used to air on Cartoon Network and now airs on Boomerang.
The Scarlet Pumpernickel (1950)
- The end where Daffy acts out the suicide of The Scarlet Pumpernickel by shooting himself in the head is cut, but Cartoon Network aired two versions of the short that edited the same scene:
- The first version ended the cartoon with an iris-out after Daffy says, "Is that all?!" This version aired when Cartoon Network showed it on their "50 Greatest Cartoons of All Time" marathon. This is also the newly-edited version that airs on Boomerang as of 2014 (though it first appeared on Cartoon Network in July of 2013), though the iris-out is replaced with a fade-out.
- The second version (which aired after the "50 Greatest Cartoons of All Time" version) edited the scene by freezing on the shot of the kreplach costing $1000 and once Daffy says, "Is that all?", it jumps to Daffy's "It's getting so you have to kill yourself to sell a story around here" line that ends the short, making it obvious to even the most naive viewer that something was edited.
Scent-imental Romeo (1951)
- The entire part where Pepe opens a bottle of champagne and tries to serve it to Penelope was cut (which is odd, because overseas Cartoon Network and Boomerang channels left it uncut, Cartoon Network once aired "The Cats Bah" with a similar champagne scene uncensored, and the offending scene from this cartoon was used in a Cartoon Network Groovies music video called "L'amour A Une Odeur")
Screwball Football (1939)
- The part after the announcer says "And there's the gun that ends the half!" where a dim-witted referee nearly shoots himself in the head with the starter pistol he has in his hand was cut (though not the end gag with the baby gunning down the man who keeps stealing licks off his ice cream).
September in the Rain (1937)
- Like most popular prints shown on television, Cartoon Network's and Boomerang's version is shown without the scenes featuring African-American caricatures.
When the short aired on Late Night Black and White, the second half of the cartoon was severely edited to remove three scenes featuring outdated African-American stereotypes:
- The boy winding up a "Sambo Jazz Band" toy.
- A white baby doll falling into a bucket of coal and emerging in blackface to say, "Mammy!" to which a nearby Mammy doll responds, "Sonny boy!"
- The white doll from "Red-Headed Baby" and two black dolls (who look like Honey from the "Bosko and Honey" shorts and were also in "Red-Headed Baby") singing a chorus of the title song.
A Sheep in the Deep (1962)
- Much like CBS, the Cartoon Network and Boomerang version (barring the version shown on Boomerang's streaming service) only cut the part during Sam and Ralph's lunch break where Sam and Ralph smoke (though Ralph cleaning his pipe with his foot was left in).
The Sheepish Wolf (1942)
- The part where the black sheep with a Rochester voice warning the sheepdog about a wolf in sheep's clothing was cut on the American versions of Cartoon Network and Boomerang, but not the international versions.
Show Biz Bugs (1957)
Like most examples here, Cartoon Network and Boomerang (American feed) flip-flopped in airing this short both censored and uncensored. In the early days of the network, the short was uncut. However, come the late 1990s into the 2000s, two edited versions of the short cropped up:
- The ending with Daffy drinking a mixture of dangerous chemicals was initially edited with a frozen shot of Bugs looking on in shock to his right covering up the part where Daffy drinks gasoline, nitroglycerine, and gunpowder (contrast with the ABC and The Merrie Melodies Show version, where only the gasoline drinking is cut). This edit lasted until 2003.
- The 2003 version is similar to the versions aired on CBS, the WB, and the BBC, where the cartoon ends after Daffy gets blown up by the booby-trapped xylophone (only Cartoon Network's version didn't add applause like the BBC version did or scant audience laughter like the version shown on The Looney, Looney, Looney, Looney Bugs Bunny Movie).
As of 2011, Cartoon Network and Boomerang America have aired this short uncensored.
The Sour Puss (1940)
- Barring its appearance on The Bob Clampett Show, Cartoon Network has aired both a computer-colorized and a black-and-white version that cut the scene of the canary shooting itself in the head after seeing how happy the cat is about going fishing.
Southern Fried Rabbit (1953)
- Sam's introduction scene where he comes out of a trench, yelling "CHARGE!" was cut because it showed the Confederate "bars and stripes" flag (which is a highly controversial flag in American history).
- The entire scene of Bugs posing as an escaped slave coming back to the South, only to blow his cover by singing "Yankee Doodle", then placing a whip in Sam's hand, begging and groveling Sam not to beat him, and Bugs posing as Abraham Lincoln and chastising Sam about whipping slaves was cut, going from Sam saying, "So, scram, Yankee!" to Bugs diving into a hole in a tree.
Speaking of the Weather (1937)
- The short scenes containing Zulu natives running towards the camera and throwing spears were cut, although their hollering can still be heard in the background when the thug bounces on the spears thrown at him.
When this short aired during ToonHeads' special about lost, obscure, and rare Warner Brothers cartoons (on both Cartoon Network and first volume of the Looney Tunes Golden Collection), the following edits were done (when "Spies" aired as part of a regular episode of ToonHeads about Private Snafu shorts, this short was uncut, possibly because that episode aired late at night while ToonHeads: The Lost Cartoons aired during primetime, which calls for more family-friendly programming):
- The shot of a buck-toothed, bespectacled Japanese spy posing as a baby and saying, "Oh, I bet we find it out," during Private Snafu's opening rhyme was cut.
- When Snafu is in the phone booth talking to his mom about his upcoming mission, the original version shows another Japanese spy inside the phone listening in. On the ToonHeads edited version, the spy's appearance is digitally covered up with a black square (this edit is a bit hard to pinpoint, unless you have seen the original version or notice the digital editing job, as the black square does stand out a bit). While those two shots of Japanese spies were edited, one scene showing a Japanese spy in a fake phone booth next to the real one (alongside a German and an Italian spy) and a caricature of Hideki Tojo reading a magazine next to a caricature of Herman Goerring and Benito Mussolini were not edited in any way.
- The part where the alcohol Snafu consumes roils in his stomach and the fumes go to his head and melt the padlock and chain in his brain had the stomach roiling shortened, the fumes melting the padlock and chain sped up, and, for reasons unknown, the snippet of Raymond Scott's "Powerhouse" redubbed with a generic jazzy tune.
The Stupid Cupid (1944)
Two different censored versions of this cartoon (both of which cut the scene of the cat shooting himself in the head after the dog gets hit by Cupid's arrow and declares his love for the cat) exist on Cartoon Network, Boomerang, and on Latin America's Tooncast channel:
- The a.a.p. version (which aired on Cartoon Network before 1995 and currently airs on Latin America's Tooncast channel) removes the entire scene featuring the cat and the bulldog, making the cartoon go from the horse getting hit with Cupid's arrow and gleefully bouncing around the barnyard after kissing the female horse to Daffy bathing in a trough and Cupid Elmer about to target him.
- The 1995 dubbed version (which aired on Cartoon Network after 1995 and is the version that currently airs on Boomerang) leaves in the part with the cat and dog fighting, Cupid Elmer firing his arrow at the dog, and the dog suddenly sounding like Charles Boyer and declaring his love for the cat, but as soon as the cat shrugs his shoulders, the edited version fades into the scene of Daffy bathing in a trough and Cupid Elmer about to target him.
Swooner Crooner (1944)
- The Al Jolson rooster auditioning with "September in the Rain" was cut.
Tortoise Wins by a Hare (1943)
- The ending where the gambling ring shoots themselves after realizing that they've been trying to sabotage Bugs throughout the cartoon has been cut on Cartoon Network (barring its appearance on The Bob Clampett Show) and currently airs with this edit on Boomerang.
Toy Trouble (1941)
- The scene where the Bookworm accidentally turns on a blackface jazz band toy and Sniffles turning it off and telling him not to touch anything else or they'll be in trouble was cut.
Trap Happy Porky (1945)
- The opening, featuring a sign that reads, "Uncle Tom's Cabins -- Boarders Taken (For All They've Got)" was cut on American Cartoon Network and Boomerang. However, it has aired uncut on overseas Cartoon Network and Boomerang channels and, in 2009, at least one showing of this short on Cartoon Network's Looney Tunes compilation show in the United States has aired this cartoon with the opening establishing shot uncut (whether this was a mistake or intentional is not known).
The Weakly Reporter (1944)
- Two bridge scenes to gags, showing female stick figure soldiers incapacitating Nazi stick figure soldiers (one by hitting him with a rifle that has a rolling pin attached to it and another by shooting a girdle out of a cannon at a group of stick figure Nazi soldiers) were cut.
Which Is Witch (1949)
- Though Cartoon Network America banned this short from airing (as mentioned above, this is one of the 12 banned Bugs Bunny shorts scheduled to air on the 2001 June Bugs that advertised every Bugs Bunny short ever made), Cartoon Network Japan did air this short, but their version, much like CBS' version back in the 1980s, was cut to remove the entire sequence of Bugs being forced in the cauldron by Dr. I.C. Spots, then freaking out after Spots puts the pressure cooker lid on the cauldron (the scene of Bugs posing as a Zulu native wasn't cut like it was on Nickelodeon).
Wholly Smoke (1938)
Cartoon Network and Boomerang aired a redrawn colorized version that cut and altered some racially insensitive sight gags:
- The beginning of the "Little Boys Shouldn't Smoke" song recolored the four matches harmonizing a la The Mills Brothers from blackface to red face.
- The scene of the pipe cleaner sticking his head in a pipe and coming out looking and singing like Cab Calloway was cut rather obviously, as this version showed the pipe cleaner walking out and looking around, but immediately cut to the Cuban cigars scene.
- The Indian cigars dancing around Porky (which came after the Cab Calloway part in the uncut version) was cut, making the cut from the pipe cleaner scene to the Cuban cigars scene more jarring. However, the Indian cigars part was seen during the end montage to cover up the Cab Calloway part.
Wideo Wabbit (1956)
- Much like the version shown on the WB network, the post-2001 cut of this cartoon (pre-2001 was uncensored), edited the part where Elmer is on the "You Bet Your Life" parody called "You Beat Your Wife" (as the title is a reference to spousal abuse and domestic violence) by cutting out all references to the title in the dialogue (which made for very choppy and incoherent dialogue) and digitally removing the title on the podium (in contrast to the WB's flickering square that covered up the offending title, Cartoon Network's covering up of the title was more seamlessly done, thanks to the digital editing programs they had at the time that they used to censor offending imagery in the anime they showed on Toonami).
Wild and Woolly Hare (1959)
- The Injun Joe scene (where Injun Joe goes out to face Yosemite Sam by himself, gets shot, and the cowboy who held Injun Joe's beer before he left drinks it and tells the audience that he gets more free beer this way) was cut.
A Wild Hare (1940)
- Like most television versions of this cartoon, Cartoon Network and Boomerang aired the version where Elmer's second guess when Bugs plays "Guess Who?" with him is "Barbra Stanwyck" rather than "Carole Lombard" (who, two years after the cartoon was released, died in a plane crash).
The Wise Quacking Duck (1943)
- Cartoon Network's Arabian channel cuts the entire part where Daffy stripteases to distract Mr. Meek (since this scene is considered inappropriate in Arabic countries which uses Islam as its main religion).
Yankee Doodle Bugs (1954)
- The sequence where Bugs tells the story of how the Dutch sold Manhattan back to the Native Americans for a song, with one of the Native Americans taking the sheet music and running off yelling "Me rich chief! Me rich Superchief!" was cut completely (compare with ABC's version on The Bugs Bunny and Tweety Show, which just cut the part where one of the Native Americans runs away with the sheet music, yelling "Me rich chief! Me rich Superchief!").
