THE SIMPSONS TRICK-OR-TREAT FOR SPINE-CHILLING TALES ON "THE SIMPSONS" SUNDAY, FEBRUARY 26, ON FOX

Aron Ralston ("127 Hours") Make Guest Voice Appearance

In the spooky opener of the 22nd annual installment of "Treehouse of Horror," Homer takes a dangerous dive into an isolated canyon on Candy Peak, but when a crashing boulder traps his arm, he channels Aron Ralston (guest-voicing as himself) to save himself. In "The Diving Bell and Butterball," the first of three hair-raising Halloween tales, a venomous spider bite leaves Homer paralyzed, but when Lisa discovers Homer's ability to communicate through natural gases, he is able to express his love for Marge. The killer spells continue in "Dial D for Diddly," when Ned Flanders, devout preacher by day, transforms into a cold-blooded vigilante by night. In the final terrifying tale, "In the Na'Vi," Bart and Milhouse are sent on a mission to obtain a sacred extract on a distant planet. They morph into the land's indigenous one-eyed avatars, but when Bart finds love and an eternal mate abroad, he is caught in planet warfare in the "Treehouse of Horror XXII" episode of THE SIMPSONS airing Sunday, Feb. 26 (8:00-8:30 PM ET/PT) on FOX.
