B.I. Bartificial Intelligence
In this Spoof of A.I. Artificial Intelligence, Bart winds up in a two-week 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 wakes up from his two-week 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 to become a cyborg, returns home and saws David in half with a chainsaw when David tries to use Homer as a shield, and Bart cuts through both of them. 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. Marge reluctantly says she'll call work and tell them Homer can't make it in, much to his delight.
Survival of the Fattest
In a parody of The Most Dangerous Game, men from Springfield arrive at Mr. Burns' mansion to go hunting. Unbeknownst to them, they are the prey to be hunted and broadcast on television. 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 newscasters.
In a parody of , the Buffy the Vampire Slayer episode "Halloween" and the classic Twilight Zone episode "The Masks", the citizens of Springfield dress in their Halloween costumes for a costume contest that involves courage, bravery and happiness. The winner is declared to be a strange old witch with a green skin and a black-and-red suit. 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 As a result, her reward is rescinded because she is not in actual costume and is sentenced to four weeks in jail as a punishment for admitting a secret silliness. In anger of such harsh punishment, she turns everyone into their costumed characters, just before being put into custody. The only person who can reverse the spell is Maggie, who was costumed as a witch. Maggie turns them all into pacifiers with their normal heads instead, flying off on a broom to seek help after this mistake she made. The segment ends as Moe and a transformed Dennis Rodman talk to the audience about the importance of reading, before Maggie returns and casts another spell, presumably turning everyone back to normal.
