Homer vs. the 18th Amendment.Alcohol is banned (thanks to a pre-existing law) from Springfield after Bart accidentally gets drunk at a town parade. Rex Banner is appointed to replace Chief Wiggum as police chief to enforce the new laws and stop Fat Tony from smuggling. Rex is successful, but then Homer starts to smuggle alcohol. Eventually, Homer ends his bootlegging ends and approaches Wiggum with a plan to expose himself and restore Wiggum's good name. Homer is about to receive punishment by being catapulted, but he is saved by an impassioned speech by Marge. The liquor ban's repeal is then revealed and the town celebrates by getting drunk.
