Season 12

This year's Halloween story sees The Simpsons as "The Munsters" (with everyone except Lisa getting killed), Homer as a wandering spirit on the hunt for a good deed in "G-G-Ghost D-D-Dad," Bart and Lisa as peasants in a fairy tale forest in "Scary Tales Can Come True," and Lisa inadvertently dooming mankind by rescuing a dolphin in "Night of the Dolphin."

While calling Animal Control over a badger taking residence in Santa's Little Helper's doghouse, Homer discovers that Springfield has two different area codes–and ends up leading a revolt that splits the town in two.

Krusty takes parenting lessons from Homer when, during an outdoor book fair, a girl tells Krusty that she is his long-lost daughter from a one-night stand with a female soldier who fought during the first Gulf War.

Lisa falls for the teenaged leader of a militant environmentalist group and tries to impress him by living in Springfield's oldest tree in order to keep it from being cut down.

When the Simpsons once again have financial problems, Mr. Burns pays Homer to play pranks on others and humiliate himself in public. Meanwhile, Smithers creates a Malibu Stacy-themed musical.

Homer decides to buy a computer after turning up to the Plant to find it closed by e-mail. He then creates his own website and it eventually gains attention when he posts gossip. Homer dubs himself as "Mr. X" to conceal his identity. When he reveals that he is Mr. X, he becomes drugged into a mysterious island where people who know too much are imprisoned after Homer starts writing conspiracy theories such as flu shots.

Homer and Bart become father–son con artists (after Bart is given money out of pity when Homer decided to not take him home), but soon find that they are the ones being had.

A snowstorm traps the students of Springfield Elementary inside, with them overthrowing Principal Skinner when he uses his Army skills to control them. Meanwhile, Homer tries to rescue the children–using Flanders' car.

While working as a human guinea pig (to pay off the family's lost savings after making a bad investment), Homer discovers the root cause of his subnormal intelligence: a crayon that was lodged in his brain ever since he was a boy. He decides to have it removed to increase his IQ, but discovers that being smart does not necessarily equal being happy.

Marge tries to rehabilitate a convict with remarkable artistic talent. Meanwhile, Homer uses a trash can to fix people's spines.
