Treehouse of Horror XV

S16 E1: This year’s thrillogy features “The Ned Zone,” in which a knock to the noggin of Ned Flanders uncannily enables him to foretell the future — or does it. Also included are in “Four Beheadings and a Funeral”, a knife-wielding killer roams Victorian London, and “In the Belly of the Boss," a fantastic journey (okay, voyage) through what can charitably be called the body of Mr. Burns.
