Homer's silhouette appears next to Alfred Hitchcock's iconic silhouette. He emerges out and warns viewers the following episode may scare certain viewers, especially Christian ones, an announcement mirroring what Marge did in the beginning of "Treehouse of Horror"s I and II. He requests for the television to be turned off before daring viewers, imitating a chicken. The TV screen eventually switches off, however, Homer and Marge can still be heard if not seen. The episode pans to a cemetery and eventually to the Simpsons' house, with the family doing their couch gag as skeletons.

The Simpsons are having a Halloween party, and they tell scary stories. The Halloween costumes include Homer as Julius Caesar, Marge as an ancient Egyptian, most likely Cleopatra, Bart as Alex DeLarge from A Clockwork Orange, Lisa as the Statue of Liberty, Milhouse as Radioactive Man, Martin as Calliope, Nelson as a pirate, Janey as a princess, Wendell as an astronaut, and Lewis as Frankenstein's Monster.
