Sidekick for a Day is an episode of Taz-Mania directed by Douglas McCarthy. It first aired 27 Nov 1993.
Plot[]
Bull fires Axl and replaces him with Taz. Axl disapproves of the way Taz performs his sidekick duties, but keeps falling for Bull and Taz's traps. Bull never notices when they catch Axl; he is more concerned with teaching Taz lessons for improper sidekick behavior, although every time he tries to administer a "lesson," Taz gives him one first.
When Bull finally sees Axl caught in a trap, he immediately cuts him down. He says the whole thing was one big lesson and Taz was in on it. When Bull asks Axl to show him what he's learned, Axl gives him a lesson of his own.
