In a subplot, Bart and Lisa stay at the Springfield Retirement Castle with Grampa, and they discover a metal detector in his closet. While Bart uses it to look for pirate treasure, they uncover an alternate ending to "Casablanca". After playing the scene on a projector screen it turns out to be a very sanitized and typical Hollywood happy ending, where Humphrey Bogart and Ingrid Bergman's characters marry in the end. Bart, Lisa and Grampa all like it but one of the spectators, the Old Jewish Man, reveals that he was once a studio executive and tried to include this happy ending to the film. Disgruntled, he pays Bart and Lisa to re-bury the film reel, along with another reel of a killing spree ending to "It's A Wonderful Life".
