Bart-Mangled Banner
After receiving an injection from Dr. Hibbert, Bart becomes temporarily deaf, which makes him impervious to being bullied, until he accidentally moons the American flag during a donkey basketball game, prompting everyone in town to accuse the Simpsons of being unpatriotic under the new "Government Knows Best" Act.
