Trivia / The Simpsons S 29 E 4 Treehouse Of Horror XXVIII

• Refitted for Sequel: There were on and off plans to parody The Exorcist in a Treehouse episode for decades before it happened in this episode. The first plan was to have Lisa possessed in the opening of "Treehouse of Horror VI"; later, Homer was possessed in a fakeout ending of "Treehouse of Horror XVI".
