The first segment is titled "The Others." It opens with the Simpson family living in a haunted house. The family is oblivious to the fact that they are being haunted by the spirits of the previous owners, who are portrayed as a ghostly family. The ghosts, led by a spectral version of the father, are frustrated that the Simpsons are living in their home. They attempt to scare the Simpsons away, but the family remains unfazed by their ghostly antics. The ghosts become increasingly desperate, trying various methods to frighten the Simpsons, including moving objects and creating eerie sounds. However, the Simpsons continue to go about their daily lives, completely ignoring the supernatural occurrences. Eventually, the ghosts realize that they are stuck in the house and cannot leave, leading to a humorous confrontation where they express their frustration at being unable to scare the Simpsons.

The second segment is titled "Freaks, No Geeks." This segment parodies the classic film "Freaks." It begins with a carnival setting where Bart and Lisa are part of a freak show. Bart is portrayed as a "human pin cushion," while Lisa is a "human saxophone." The carnival is run by a sinister ringmaster who exploits the children for profit. As the story unfolds, Bart and Lisa discover that they have been transformed into freaks due to a curse placed on them by a witch. They must find a way to break the curse and return to their normal selves. The siblings band together, using their unique abilities to outsmart the ringmaster and the witch.

Bart and Lisa work together to defeat the witch, ultimately breaking the curse and returning to their normal lives.

The third segment is titled "The Telltale Head." This segment is a retelling of Edgar Allan Poe's "The Tell-Tale Heart." It begins with a young Bart Simpson who is feeling guilty after he steals the head of a statue from the town square. The statue is of Jebediah Springfield, the town's founder. As Bart tries to hide the head, he becomes increasingly paranoid, believing that the statue is watching him. He hears a constant heartbeat that grows louder and louder, driving him to the brink of madness. Bart's internal struggle is depicted through a series of surreal and darkly comedic sequences, showcasing his descent into guilt and fear.
