The annual ThreeShorts HalloweenEpisode starts with [[MeaningfulName Fox Censor, the FOX network censor,]] editing this year's Halloween special to a TV-G rating (removing all the NBC-style sexual innuendo and CBS-style action violence), but the TV rating bug fights back by stabbing Censor until it reaches TV-666.

!!The Homega Man

A parody of ''TheOmegaMan'' (aka the second movie adaptation of ''I Am Legend''). France threatens to destroy Springfield in response to a racist "frog legs" joke Mayor Quimby made, and Marge convinces Homer to look into getting a proper bomb shelter just in case. As it turns out, while he's inside one to examine it, the French see their threat through with a neutron bomb, and he emerges to discover he's apparently the last man in Springfield.

He indulges in all the town's leftover pleasures until a mob of Springfieldians mutated by the bomb (including Moe, Dr. Hibbert, etc.) arrive to make a meal of him. A car chase through town ensues, and Homer winds up back at his own house to discover his family alive and well -- the house's multiple coats of lead paint created "the perfect bomb shelter." The mutants are touched by the reunion and Marge suggests the two groups can be friends -- but it's a ruse to ensure the mutants' guards are down, as she and the kids promptly kill the mutants with shotguns. "Now ''that's'' the Marge I married!" exclaims the impressed Homer.

!!Fly vs. Fly

A parody of both TheFifties and TheEighties versions of ''TheFly''. The Simpson family attends Professor Frink's garage sale and Homer winds up buying a matter transporter. He promptly puts its two pods to good (to him, anyway) use and forbids Bart from trying it out for himself. In the middle of the night Bart tries to send Santa's Little Helper through it; instead both it and Snowball II go through at once. When Bart sees the result -- two hybrids, one combining dog and cat front ends and one combining dog and cat rears ("Ewwww, you can be Lisa's!") he's intrigued by what would happen if he and an ordinary housefly buzzing past went through together...

Expecting to come out as "Superfly", Bart is disappointed to find that he and the fly's heads have been proportionally swapped. Still, the undaunted Bart!Fly heads out to cause mischief while grotesque Fly!Bart is reluctantly accepted by the other Simpsons. When Bart!Fly realizes that Fly!Bart's usurped his place in the household, he reveals himself to Lisa and she agrees to help him reverse the process. Fly!Bart attacks them both, but Lisa manages to knock it into the transporter with Bart!Fly and both are restored to normal. Homer, seeing what the transporter has wrought, grabs an ax and vows to do what he "should have done a long time ago" -- and chases Bart around the house for playing with the machine.

!!Easy-Bake Coven

A parody of ''Theatre/TheCrucible''. In 17th-century Springfield, Marge is accused of witchcraft. She pleads innocent, and it's decided to toss her off of a cliff to reveal the truth -- if she's innocent, she'll fall to her death, if she's guilty, she'll be able to magically escape. As it turns out, she ''is'' a WickedWitch, and flies off on her broomstick to her family and the townsfolk's horror. At their mountain hideaway, Marge reunites with her sisters/fellow witches Patty and Selma, and soon they head out to find some delicious kids to eat.

The Flanders family finds themselves a target of the witches' intent, but before the threesome can haul off Rod and Todd, Ned and Maude offer them ''gingerbread'' kids instead. The witches find the cookies sufficiently tasty and spare the Flanders children, wishing they hadn't filled up on kids at their previous stops. According to Captain [=McAllister=], placating witches with treats was the origin of trick-or-treating, and the following year kids all over town happily go door-to-door for goodies. Homer, on the other hand, decides to egg a house -- which Lisa points out is his own. So he accuses ''her'' of being a witch and a mob promptly runs her out of town.

!!This episode contains examples of:

* AccidentalMisnaming: When Marge tells her sisters about being exposed as a witch, one of them comments that this means she finally left "Durwood", and Marge corrects them about Homer's name. But they don't care, of course.
* AngryFistShake: In "Fly vs. Fly", Fly!Bart tricks a spider into thinking that he's caught in its web. When he's about to be eaten, he slaps the arachnid and flies away. The spider watches him in anger, shaking its four legs in synchronized movement, probably swearing revenge.
* ApocalypseAnarchy: Homer really enjoys being the last man alive. He goes dancing to the church, completely naked.
* BodyHorror:
** The effects of Bart crossing into the matter transporter with the fly's head on his body.
** The mutants in "The Homega Man," who appear to be rotting. Wiggum at one point says that it "really brings a tear to your eyesocket" just before his eyeball falls out.
* BurnTheWitch: What accused witches are sentenced to in old Springfield until they are deemed fit to return to society again.
* DroolHello: Done by Bart!Fly in "Fly vs Fly".
* GoshDangItToHeck: The FOX censor, [[CensorshipBureau appropriately enough]], utters these each time he is stabbed.
* HalloweenEpisode
* Magazine/{{MAD}}: The title "Fly vs Fly" is a parody of Mad Magazine's "Spy vs. Spy", written in the ''Spy'' logo font.
* MeaningfulName: The FOX Network censor literally named Fox Censor.
* ShoutOut: Homer is watching a Creator/ChrisFarley[=/=]Creator/DavidSpade movie at church, most likely ''Film/TommyBoy'', as Homer gleefully says "Oh, Spade... why did you put Farley in charge of the bees?".
* TheUnfavourite: Lisa in "Easy-Bake Coven"; Homer even goes so far as to [[OffingTheOffspring accuse her of witchcraft]] just because [[DisproportionateRetribution she told him he was egging their own house]].
* ThreeShorts: As per usual.
* WickedWitch: Marge, Patty, and Selma in "Easy-Bake Coven".
* WouldHurtAChild: In the second and third shorts, Homer attempts to kill one of his children: Bart for messing with his transporter in "Fly vs. Fly"; Lisa for witchcraft in "Easy-Bake Coven".
* YourMom: Literally one of the names listed in the end credits, which, in Halloween specials, are usually [[CreditsGag gag names]].
