Full Story

School is Hell

School is Hell title card.

Principal Skinner has put Bart in detention for spreading rumors about a naked lunch lady. Bored, Bart blows dust off a desk, finding an Aramaic inscription. He brings Lisa to see it; she uses an app to translate it, which transports the pair to Hellroads, where they gain demonic features. Lisa is accepted into a group of mean girls, prompting snow to fall; Lisa is stunned that it would REALLY be a cold day in hell when she was popular. Bart is caught by a two-headed demon that appears to be a hybrid of Skinner and Chalmers, who skins him and tosses him into a classroom. The teacher is asking about how to torture a bank robber, to which Bart gives the ingenious idea of feeding the money to the robber, getting back his skin as a reward. Bart then comes up with the torture of forcing a man to wear an aquarium as pants, and have it filled with piranhas; the screams would power a fan which would release more piranhas.

Lisa finds Bart, showing him a map to escape hell. They use it and unsurprisingly arrive in Mr. Burns' office, where he tells them the Earth time and thanks them for choosing his portal. At home, Bart asks Homer and Marge to let him enroll in Hell. They meet with the principal, who states that Hell encourages and nurtures the students there, winning Marge over. Bart succeeds in all of his classes in Hell, which involve practicing torture and killing Jimbo Jones. He becomes an honor student. For his final test, he must torture Homer. Despite Bart's hesitation, Homer insists as this will make up for all the times he hasn't been there for Bart.

At graduation, the principal has Webster held hostage, as he hates that fact he changed "theatre" to "theater". "BeelzeBart Simpson" graduates as valedictorian, much to the joy of his family. A headless and badly maimed Homer proudly watches.

A Clockwork Yellow

A Clockwork Yellow title card

Moe has a Clockwork Orange-style gang in London along with Lenny, Carl and Homer. Homer falls for a girl (Marge) who convinces him to quit, and the gang falls apart. 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 Eyes Wide Shut, 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

The Others title card

In a parody of The Others, The Simpson family find unexplained frosty chocolate milkshakes, blood messages that say "HELP ME" on the mirror, and that their TV only shows the long-running Fox sitcom Married... with Children, and when Homer tries to change the channel, it only shows alternate versions of the sitcom.

After a ghost attacks him in his sleep, Homer summons the ghosts, who are the family's 1987 versions 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 by cooking her head in the oven 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 he might have killed 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, due to corporate greed.

CGI versions of the Simpsons enter the home, with a talking Santa's Little Helper, followed by anime versions of the Simpsons (Maggie = Pokémon, Bart = Naruto, Marge = Bleach, Homer = One Piece, Lisa = Attack on Titan, Santa's Little Helper = Spirited Away,), Adventure Time, South Park, the animal forms of the Simpson Family, Minions from Despicable Me, the Simpsons' LEGO forms from Brick Like Me, the Simpsons from the Sylvain Chomet couch gag, and even the popular FX series Archer. The different versions of the Simpsons all notice each other, coming to the conclusion that something has manipulated them into arriving at the same house in the wrong universe.

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, and the photo is ruined.
