Bugs is being hunted by a dog named Willoughby, but the dog falls for every trap Bugs sets for him until they both fall off a cliff.
Originally, the ending scene had Bugs and Willoughby fall off three cliffs. After the second tumble, Bugs then told the audience, "Hold on to your hats, folks. Here we go again!" during the third trip down. Schlesinger interfered with the production of this scene; the most popular story is that the "Hold on to your hats" line referred to a sexual euphemism (or punchline to a dirty joke) that was then in circulation (though a similar line had been allowed in "Daffy Duck & Egghead": "Hold your seats, folks, here we go again!"). Another possible story was that Leon Schlesinger objected to the end because he didn't like the idea that Avery possibly killed off Bugs Bunny, since the cartoon ended with Bugs and Willoughby falling off a cliff.
According to Martha Sigall, Schlesinger objected to how repetitive and overly-long the second fall was. He instructed Avery to cut it. Avery insisted that it should remain, but, as the boss, Schlesinger insisted it be removed. From Schlesinger's point of view, the dispute was over his right to do as he pleased with the films he was funding. From Avery's point of view, the dispute was over artistic interference.
Avery was suspended for four weeks for the dispute with his boss. The quarrel was reported in an article for The Hollywood Reporter on 2 April 1941. From Schlesinger's point of view the dispute was over his right to do as he pleased with the films he was paying for. From Avery's point of view, the dispute was over artistic interference. During his suspension, Avery was hired by Paramount, where he worked on the first three Speaking of Animals shorts and later MGM where he stayed for most of the 1940s and 1950s, creating such classic cartoons as "Red Hot Riding Hood" (and all the cartoons that feature the Wolf and Red the showgirl, such as "Swing Shift Cinderella", "Little Rural Riding Hood", and the now-controversial "Uncle Tom's Cabana"), "Blitz Wolf", "One Cab's Family", and cartoons featuring characters such as Droopy Dog and Screwy Squirrel.
- Most televised versions of this cartoon, specifically the versions shown on the Ted Turner-owned cable networks such as TBS, TNT, Cartoon Network, and Boomerang, cut out Willoughby saying "Yeah!" as the cartoon ends to cover up the fact that the cartoon has a missing ending (see "Lost Ending" for a detailed explanation). The version released on most home media versions (VHS, LaserDisc, the Golden Collection DVD set, and on the HBO Max streaming service) does not restore the lost ending, but does leave in Willoughby saying, "Yeah!" just as the short abruptly ends.
- In Super RTL (Germany, Austria and Switzerland) airings of this short, the Bugs and Willoughby falling gag is shortened.
- This is the second-to-last Bugs Bunny cartoon directed by Tex Avery to be released. The last, "All This and Rabbit Stew", was produced before this film. Additionally, it was the fifth cartoon for Bugs and the 55th cartoon Avery directed at Warner Bros.
- The Merrie Melodies opening sequence also featured the first usage of the Warner Bros. shield logo zooming in with a carrot-munching Bugs Bunny lying on top of it. Here, after the zoom-in and a couple of bites of his carrot, Bugs pulls down the Merrie Melodies title screen like it is a shade.
- Starting with this cartoon, the words "WARNER BROS." and "Present" are already on the screen, and would be for all future Bugs Bunny cartoons, excluding "Hold the Lion, Please" and "A Corny Concerto", until "Bugs Bunny Nips the Nips". However, beginning with "All This and Rabbit Stew", Bugs does not pulls down the Merrie Melodies title screen like a shade as in this cartoon; instead the WB shield title then fades to the Merrie Melodies title screen. After "Nips the Nips", the Bugs Bunny head would appear after the WB shield zooms in starting with "Hare Ribbin'".
- From 1941 to 1944, in this Warner Bros. shield logo zooming in with a carrot-munching Bugs Bunny lying on top of it, Bugs Bunny always bites on his carrot twice. The only exception of such is the 1944 Blue Ribbon reissue of "Hiawatha's Rabbit Hunt", where Bugs bites the carrot only once, and munches on it for a much longer time.
- 1945 saw a revamped version of the Warner Bros. shield logo zooming in with a carrot-munching Bugs Bunny lying on top of it, beginning with "Hare Trigger" and ending with "Hare Do". This version uses the modern Bugs Bunny design by Robert McKimson, and once again Bugs pulls down the Merrie Melodies/Looney Tunes title screen like a shade as in this one (though this time, another noticeable difference in the animation is that Bugs bites on his carrot only once and munches on the carrot for a much shorter time). Bugs' head would appear again replacing the WB shield in every Bugs cartoon from 1949 (except for "Hare Do") until the Termite Terrace studio closed.
- The European 1995 Turner print has the 1947-1948 Merrie Melodies dubbed ending card and keeps also the 1941-1955 ending music rendition of "Merrily We Roll Along". It has also Willoughby's line before the ending credits intact. The American 1995 Turner print has the 1937-38 Merrie Melodies dubbed card and replaces the 1941-1955 ending music rendition of "Merrily We Roll Along" to the rendition that was shown on the 1938-1941 Merrie Melodies cartoons.
