[2] In this episode, Bart denies committing a prank but is put on trial while Mr. Burns decides to be a superhero.
[3][4] While performing at an Easter celebration, the Springfield Elementary band members inadvertently launch hundreds of eggs from their instruments, ruining the townspeople's clothes and splattering the streets.
Smithers, fearful for Burns' safety, stages numerous crimes for his boss to thwart, using Homer, Lenny, Carl, the Crazy Cat Lady, and other citizens as paid fake villains for Fruit Bat Man to "defeat".
As Marge washes the town's clothes, she and Lisa notice that Groundskeeper Willie's kilt is stained with only one egg, which appears to have been crushed into it by hand.
Realizing that Willie is the culprit, Lisa confronts him; he confesses to committing the prank due to his hatred of the Easter holiday (as he is a Scottish Old Believer Presbyterian) and shreds the kilt to destroy the evidence.
Before the end credits, there is a trailer for the "Dependables", a spoof that casts several of Springfield's elderly residents as a superhero team.
The producers offered former United States Attorney General Janet Reno to appear as herself in August 2012.
