Krusty Gets Busted.While buying ice cream at the Kwik-E-Mart, Homer witnesses a robbery perpetrated by a man believed to be Krusty the Clown, host of the "Krusty the Clown Show", Bart's favorite program. Krusty is sent to jail and his show is taken over by his assistant, Sideshow Bob. Bart is certain that Krusty is innocent, and gathers evidence to support his claim, which he takes to "Krusty's bestest friend", Sideshow Bob. Bart realizes that the robbery was actually committed by Bob, who was trying to frame Krusty. Bob is arrested and Krusty thanks Bart for saving him.
