Bart decides to sell his soul to Milhouse for five dollars. Meanwhile, Moe transforms his dank, depressing Tavern into a family restaurant called Uncle Moe's Family Feedbag. When he stops finding Itchy & Scratchy funny and can no longer activate the automatic doors at the Kwik-E-Mart, Bart realizes that he really has lost his soul. Determined to recover it, he tracks Milhouse down at his grandmother's apartment and begs for his soul back. Milhouse tells Bart that it's too late, because he has already traded the soul for a handful of Alf Pogs. Over at the restaurant, Moe is exhausted by the constant smiling, good will and hospitality necessary to meet the demands of his new customers. Bart waits all night outside the comic book store to buy his soul back, only to learn that it has already been purchased. Depressed, Bart goes home and prays for the return of his soul. Just then, it is given back to him--by Lisa, who bought it the day before.
