What do you do when Bart ruins Christmas? That’s easy: go on Jeopardy to try and win some cash for presents. This may have seemed like great logic to Marge in the episode “Miracle on Evergreen Terrace” in which Bart burns down the Christmas tree, lies about it, and gets the entire town of Springfield to give his family $15,000, but she clearly proved her lack of knowledge of game show trivia in this one. As a guest star, Alex Trebek lends his likeness — and classic game show manner — in one of the funniest episodes of the ninth season. He even gets in on the “community payback” toward the end of the episode.
