YMMV / The Simpsons S 7 E 18 The Day The Violence Died
Ass Pull: A rare intentional and Played for Laughs example, with Bart and Lisa being beaten to the punch from saving Itchy and Scratchy Studios by their lookalikes who weren't even once foreshadowed and abruptly come out of nowhere.
Memetic Mutation: The scene where Lionel Hutz adds punctuation to his newspaper ad to reverse what it promises ("Works on contingency? No, money down!") is used frequently in response to politicians who have been accused of backflipping on previously stated policies.
Suspiciously Similar Song: The music that plays during Itchy and Scratchy Meets Fritz the Cat is very similar to Earth, Wind & Fire's "Shining Star," particularly the moment when Itchy smokes a cigarette and lights Scratchy on fire.
