Hands out its annual Halloween treats on the "Treehouse of Horror XV" special featuring three deliciously frightful mini-episodes. In "The Ned Zone," Ned Flanders gains the power of foretelling people's deaths after suffering a head injury, and is shocked to discover that he will be the one to kill Homer. In the second short, "In the Belly of the Boss," Maggie is shrunken inside a vitamin capsule in a freak science accident and is swallowed by Mr. Burns. The final Halloween scare, "Four Beheadings and a Funeral," is set in Victorian London, where Master Detective Eliza Simpson and her faithful sidekick, Dr. Bartley, attempt to catch The Muttonchop Murderer, a Jack the Ripper-esque serial killer.
