A Clockwork Yellow

Years later, Moe is attacked at home in a style similar to his gang's former ways, and asks Homer to bring the gang back together. Lenny and Carl, who have become policemen, join them. They attack a masked orgy, similar to the Stanley Kubrick film , and several other of his films are parodied in a fight sequence. Kubrick is then shown in an editing room and asks for the entire film to be reshot.

The Others
In a parody of , The Simpson family find unexplained frosty chocolate milkshakes, blood that says "HELP ME" on the mirror, and that their TV only shows the long-running Fox sitcom Married... with Children.

After a ghost attacks him in his sleep, Homer summons the ghosts, who are the family's 1987 selves from The Tracey Ullman Show. Homer is attracted to the ghost Marge, who prefers him to the former grumpy ghost Homer, so the jealous living Marge kills herself to become a ghost. The ghost Homer becomes jealous and bludgeons the living Homer to death with a toaster. Bart fakes suicide to join the ghosts, tricking Lisa into actually killing herself. Her ghost then murders Bart as revenge. Groundskeeper Willie takes the children's corpses to make stew, and it is implied that he murdered Maggie. Homer chooses his modern-day wife over the older ghost. The next morning, at the breakfast table, Lisa asks if there could ever be any other incarnations of the Simpsons, and a range of Simpson families based on other animations is then shown, including ,, , , , , the animal forms of the Simpson Family, Minions from , the Simpsons' LEGO forms from Brick Like Me, the Simpsons from the Sylvain Chomet couch gag, and even the popular FX series Archer. The segment finishes with the 1987 version of Homer unsuccessfully trying to photograph a good portrait of the two families together, a direct homage to the short "Family Portrait" from The Tracey Ullman Show.
