Treehouse of Horror XVI

In this spoof of A.I. Artificial Intelligence, Bart winds up in a deep coma after attempting to jump out of a window into a swimming pool. The family takes in a robotic boy, named David, who quickly proves to be a better son. Bart soon wakes up from his coma and competes against David for the affection of the rest of his family. However, Bart is dumped on a road by Homer, who decides to keep David instead. When Bart finds a group of old rusty robots, he steals their parts at night to become a cyborg. Angry that Homer abandoned him, he then returns home and cuts through both David and Homer with a chainsaw after the robot tries to use Homer as a shield. Although the family is now together again, Homer is angry that he has to be fused with David's lower half, which soon collapses due to Homer's weight. Suddenly, the whole scenario is revealed to be a dream conjured by Homer's demonically possessed mind as he is being exorcised by a priest. Marge reluctantly says she will call work and tell them Homer cannot make it in, much to his delight.

In a parody of the 1924 Richard Connell short story "The Most Dangerous Game", men from Springfield arrive at Mr. Burns' mansion to go hunting. Unbeknownst to them, they themselves are the prey to be hunted, with Burns pledging that if they survive by noon the following day, they will be free to go home. The hunt is broadcast on live television as The World Series of Manslaughter, with Terry Bradshaw as a guest analyst. Homer manages to survive the night while the others are killed left and right, but Burns closes in on him in the morning. Just as he is about to be shot, Burns and Smithers are knocked out by Marge with a frying pan in each hand, who then hits Homer on the head for being away from home for 18 hours without calling, before they end up having make-up sex behind the astonished Bradshaw.

In a parody of The Twilight Zone episode "The Masks",[1] the citizens of Springfield dress in their Halloween costumes for a semi-annual contest party. The winner is declared to be a strange old green-skinned witch. When given the award and asked who she is, she is forced to admit that she is a real witch. As a result, her reward is rescinded because she is not in actual costume. In anger over losing her gift certificate, she turns everyone into their costumed characters, including transforming Homer into a decapitated human, Marge into a skeleton, Bart into a werewolf, Lisa into Albert Einstein, Dr. Hibbert into Count Dracula, Apu into R2-D2, Patty and Selma into two halves of a horse, Milhouse into a bulldozer, Nelson into a racoon (despite protesting that he is the Lone Ranger, and too poor to afford the hat), Hans Moleman into a mole (though he complains that he wasn't wearing a costume), Moe into Hugh Hefner, Principal Skinner into a GI Joe (without genitalia), his mother Agnes into a southern belle, Sherri and Terri into Tweedledee and Tweedledum and Mayor Quimby into Mayor McCheese. The only person who can reverse the spell is Maggie, who was dressed as a witch. After the townspeople are split over being reverted to normal or being left as costumes, instead of reversing the spell, Maggie turns them all into pacifiers with their normal heads and then flies off on a broom. The segment ends as Moe and a transformed Dennis Rodman (who was in Springfield working off a speeding ticket) talk to the audience about the importance of reading.
