Nightmare Fuel: The Simpsons
You wouldn't think that a show starring a cartoonish family could be scary enough for its own page, right? Wrong
In order for Nightmare Fuel tabs to survive, a new writing style is going to be used, nicknamed Example Lobotomy. Basic rules: just list facts as they are, don't just say "character X" or "the X scene" (such zero context examples will be zapped), spoiler policy to be determined on a case-by-case basis, italics to be applied to works' names only and not to give emphasis on what tropers say. "X scared me" is already implied by the mere addition of that example by the troper.

Regular Episodes (and The Movie)
- Accidental Nightmare Fuel would qualify with earlier seasons' animation because of how crude and childish it looked as seen in Some Enchanted Evening (both the TV cut and the unaired version on the first season DVD).
- Bart Gets Famous: Lisa fantasizes about being incredibly successful and then impaling Bart on a trophy and when Bart tries to snap her back to reality, she doesn't want to because she's so happy.
- Bart of Darkness: The bit where the axe-wielding not murderer Ned Flanders slowly walks up to the attic where Lisa is, humming, "Mary Had A Little Lamb".
- "Bart Sells His Soul": where Bart sells his soul to Milhouse, in one of the darkest episodes of the series as noted by many. Bart becomes a Creepy Child pretty soon throughout the episode, eventually culminating in him threatening Ralph Wiggum.
"I need a soul, Ralph. Any soul. YOURS!"
- Bart the Murderer: The nightmare sequence from "Bart The Murderer", where the "dead" Skinner says, "YOU KILLED ME BART!".
- Bart Vs. Thanksgiving: Bart's nightmarish Imagine Spot where he thinks his family, appearing borderline demonic◊, won't forgive him for what happened with Lisa's centerpiece.
- Black Widower: During Selma and Sideshow Bob's wedding, Bart imagines Sideshow Bob as The Grim Reaper saying "I do".
- Blunder Years, The: Homer was hypnotized to age twelve. In the flashback when he pokes the stick into the drain to figure out where the water went and the decomposing (maggots and everything) corpse washes out and lands on top of him: it was Waylon Smithers Sr.
- Boy Scoutz 'n the Hood: The end where Ernest Borgnine and the other Junior Campers get attacked by an unknown someone or something hiding in the woods (though the fact that they were at an "abandoned summer camp" coupled with some tell tale sound effects, can allow a reasonable guess to the assailant's identity).
- Brother From The Same Planet: During a Nightmare Sequence earlier in the episode, Homer realizes he forgot Bart and dreams that he drove up to where Bart was supposed to be waiting and all there is left is a (spiky-headed) skeleton.
- Following that, when Homer actually does pick up Bart, Bart is left speechless in anger as Homer attempts to pass off a very shoddy apology about how "they were both wrong". Bart slowly turns to Homer and imagines his eyes and the flesh on his face melting off like wax, until Homer asks "NOW HOW 'BOUT A HUG" in a horrifying voice. While some consider this a Big Lipped Alligator Moment, in context this scene conveys just how angry Bart feels from his own point of view. He loathes Homer so much at that point he sees him as this disgusting, horrific monster◊.
- Made worse by the fact that the above image is associated with the "Dead Bart" creepypasta.
- Cape Feare: Bob's prison tattoo of Bart's severed, bloody head on a skateboard saying, "Ouch, man!"
- Homer twice scaring Bart (who's already fearing for his life because of Sideshow Bob) before bed. Particularly, the siloutte of Homer's head◊ as he's holding the knife, with glowing yellow eyes.
- Children of a Lesser Clod: Ralph getting trapped in Homer's scabbing knee injury.
Homer: It knows you're afraid.
- Eight Misbehavin: after meeting the mascot of Shøp, the following exchange occurs.
Alan Wrench: "You put it together yourself! All you need is me, Alan Wrench!"
Homer: "He's named after what he is."
Bart: "Hey, cool costume!"
Alan Wrench: [Robotic voice] "It's not a costume. They found me in a meteor!"
Marge: Where do you keep your sparkplugs?
Alan Wrench: [Normal voice] "Sparkplugs? Third aisle." [Robotic, to Bart] "Help! I need tungsten to live! Tungsten!"
- Future-Drama: Professor Frink's skeleton is shown hanging in his lab in the future, implying that he committed suicide and that no-one either noticed or cared enough to bother to look into his disappearance.
- The Great Louse Detective: Near the beginning of the episode, Homer has an Asian masseuse walking on his back, when she suddenly starts SINKING into it like it's quicksand, trying to pull herself free as she cries for help. The scariest part about that whole scene is Homer's completely nonchalant tune as he tells her not to struggle or she'll sink faster. Then it cuts to the next scene and is never talked about again. Has that happened to other people before? What happened to the lady?
- Homer vs. Lisa and the Eighth Commandment: What better way is there to instill the fear of eternal damnation into the viewer than with a vision of your family, blissfully ignorant of their surroundings, suddenly watching their stolen cable TV within the bowels of hell?
C'mon, Lisa. Watch a little cable with us. It won't cost you a thing. EXCEPT YOUR SOUL!
- Homer's Enemy: Frank Grimes' complete mental breakdown and slow descent into insanity throughout the episode.
- Homer Goes to Prep School: The Gainax Ending where a meteor is shown heading for Springfield and it's covered with zombies.
- Homer the Moe: The jukebox in Moe's bar gets stuck, leading Homer to imitate Fonzie by smashing it. Of course, he cuts his hand and bleeds out in spectacular fashion (it was pretty much a "Reality Ensues" take on what Fonzie does on Happy Days). Now you know why that scene has been cut on UK's Channel 4.
- Homer's Triple Bypass: if Lisa hadn't been there and hadn't read up on cardiology, Homer would've died at the hands of the ultra incompetent Dr. Nick Riviera.
- I Am Furious (Yellow): Homer Hulking Out. Becomes Nightmare Retardant when Bart says, "Thank God his pants stayed on."
- Kamp Krusty. The dilapidated buildings and canoes are certainly scary enough for the kids (not to mention the idea of three school bullies-cum-local teenaged thugs — one of which is actually a father, though Kearney does love and care for his son more than the other kids — being assigned as counselors), and there's also plenty of Adult Fear at the idea of your kids being sent to such a death trap with an In Name Only Money, Dear Boy connection to a popular children's celebrity.
- Last Exit to Springfield has the series of pictures of what Lisa could look like without braces. Tooth through the skull? Definitely nightmare fuel.
Bart: Cool, she'll be a freak!
- Last Tap Dance in Springfield: Homer gets laser eye surgery, but forgets (read: doesn't want to spend any further money) to use his prescribed eye drops immediately after. Both eyes are instantly engulfed by thick, foot long crusts. The whole thing is made less disturbing (or more, if you think that Homer is being kidnapped) with the scene of Kearney and his hoodlum friends taking Homer to buy Jack Daniels and smokes, and then completely forgotten about after act one.
- Lisa's First Word: The clown bed Homer made for Bart when he was a toddler.
- Lisa's Pony: Lisa's scream when she finds her horse in her bed (in a Shout-Out to The Godfather).
- Little Big Mom: The wild deer turning feral and about to murder Lisa until she's unintentionally saved by a ranger.
- My Sister, My Sitter: Bart doing everything he can to upset Lisa, getting injured and trying to make his injury worse, eventually falling unconscious… followed by Lisa’s nightmarish odyssey to get him to a doctor, resulting in the whole town thinking she’s on drugs and killed Bart.
- ''New Kids on the Blecch": Yvan eht nioj, yvan eht nioj, yvan eht nioj...
- The entire concept of the episode counts too, with a military general forcing minds into a boy and as a means of spreading pro-military propaganda and additionally, the plan to destroy a building.
- Papa Don't Leech: Homer dreaming about suffocating Grampa after a car accident. It was meant to be a funny parody of a similar scene from an episode of The Sopranos, but it was still disturbing and a sign that the days of the Simpsons writers doing the kind of dark humor that emphasizes the "humor" part are done.
- "The Parent Rap": The scene where Bart drags a tethered Homer across the baseball field and a dazed and bloodied Homer says to him "Come on, hug me."
- 24 Minutes: Bart carves the phrase "death before homework" into his arm with a knife. That's right, a child willingly injuring himself with a sharp object in a slow and painful fashion. One of the darkest moments in the series.
- Reality Bites: Snake is spanning a wire over a road with the intention of decapitating Homer when he comes driving along. Luckily, that doesn't work out. What it does accomplish however is completely severing off Kirk van Houten's arm! (In a later scene, we briefly see him with his arm now complete again in a bandage - but still...)
- Rosebud: The ending, where we see, in a distant future, men (or rather, several Homer clones) are slaves to apes, Mr. Burns is still alive in some strange robotic life support machine, and Smithers's head is grafted onto a robo-dog's body, followed by the disturbing music that plays whenever there's chaos or a riot on the show.
- Selma's Choice: Selma takes Bart and Lisa to Duff Gardens after Homer falls ill from food poisoning. The trio are on this "It's A Small World"-esque ride called, "The Little Land of Duff," with robot kids from all over the world singing, "Duff Beer for me/Duff Beer for you/I'll have a Duff/You have one too..." Bart dares his sister to drink the water. Lisa is then forced to drink it by Selma and Lisa begins tripping — first, she sees the Little Land of Duff robots fading away, then Lisa begins rambling, "They're all around me! No way out! NO WAY OUT, I TELL YOU!", and finally, Lisa sees Selma as a Medusa-like creature with multiple eyes and a snarling mouth for a shoulder. Lisa then screams and tries to beat Bart and Selma with an oar. Also counts as a CMOF.
- Separate Vocations: Snake attempting to run over and kill Bart with his car, while Bart screams in terror and covers his eyes as he braces for being hit.
- Simpsons Bible Stories: The Apocalypse, especially since the Simpsons go to hell, while the Flanderses go to heaven.
- The Summer of 4 ft. 2: Lisa imagines literary characters coming to life inside a library and enticing her inside. When Alice tries inviting Lisa to a tea party, she then immediately starts warning Lisa to get away before the Mad Hatter pulls a gun to her head.
- Tale Of Two Springfields, A: A badger mauls Homer and it appears it tore open his stomach.
Homer: What am I, a tailor?
- Team Homer: Mr. Burns (high on ether), drilling Moleman's head off-screen.
"Oh no, my brains."
- There's No Disgrace Like Home: Homer's hellish vision of his dysfunctional family compared to the family of another worker.
- A Totally Fun Thing That Bart Will Never Do Again: The breakdown of civilization on board the ship after ten days due to Bart's prank to extend the family's vacation forever, with no regard given to the consequences of his actions whatsoever. Made even more grimly ironic as the cruise started out as the funnest thing ever, but descended into a floating hellhole. It's even implied that some passengers have reverted to cannibalism.
- Trilogy of Error: The scene where Marge accidentally cuts Homer's thumb (and with blood squirting out) is surprisingly dark for a Simpsons episode that isn't part of the Treehouse of Horror series.
- When Flanders Failed: Homer's evil laugh after he wins the wishbone contest. That is, until he starts choking on his hamburger. (His wish: The Leftorium going out of business.)
- Who Shot Mr Burns Part 2: When Mr Burns can only say Homer's name after waking from his coma, it makes everyone think he shot him, not helped by the time the mob finds him, where he's practically strangling Mr Burns whilst ranting at him to tell everyone that he didn't do it. Further made worse, as Mr Burns chooses that moment to snap out of his daze and ask who the hell he is, causing Homer to completely snap, grab a nearby gun and hold it to Mr Burns's head, visibly shaking with rage.
Homer: Say it, Burns! SAY I NEVER SHOT YOU...before.
- Not to mention the ending where it's heavily implied that Maggie shot Mr. Burns intentionally as she starts shiftily looking around, all while a Scare Chord goes off and her pacifier sounds are replaced by gunshot sounds.
- "The mark of evil upon Cain's face in "Homer and Ned's Hail Mary Pass".
- The Springfield Files, with its ominous nighttime shots, spindly alien, and liberal use of the X-Files theme, is pretty damn creepy at times.
- The story Bart makes up to scare the other kids during lunch in one episode, about the murderous cafeteria cook Dark Stanley who killed the children who made fun of him and cooked them into a soup. The bizarre switch in animation during this segment doesnt help. Even worse its implied by some dialogue at the end that Dark Stanley was real!
Examples of Treehouse Of Horror living up to its name
- Treehouse of Horror:
- The Bad Dream House segment's possessed house, with blood running down the kitchen walls. Not to mention the evil spirit of the house and the way it makes the family try to kill eachother. The worst part is that it worked until Marge managed to snap them out of the spell.
The House: Lisa... Lisa... the butcher knife, Lisa...
- The episode's rendition of The Raven, by Edgar Allan Poe. The poem is narrated by James Earl Jones, with the scariest part being when Homer's character opens the chamber door to see who is knocking, and all he finds is "darkness there, and nothing more", accompanied by a shot of an impossibly long hall just stretching away into darkness.
- The sheer terror on Homers face at the knocking on the window. A better illustration of the fear Poe described as "fantastic terror never felt before" is hard to imagine.
- Treehouse of Horror II: when Homer is turned into a robot right after Mr. Burns slices open Homer's head with a pizza cutter: "Dammit Smithers, this isn't rocket science! It's brain surgery!". And then Burns puts Homer's brain on his head, while quipping: "Look, Smithers, I'm Davy Crockett!". The ending of the short has Homer waking up with Burns's head on his shoulder was worse, complete with a joke teaser for "next week's episode".
- The ending to "The Bart Zone" got me: near the end of Bart's nightmare, Bart and Homer share a heartwarming father/son moment, but when Homer kisses Bart on the cheek, it cuts right back to reality where Bart screams in an extreme close-up. Then the camera moves inside his mouth to create a black screen for the commercial break.
- Treehouse of Horror III: the Zombie Apocalypse Halloween segment "Dial 'Z' for Zombies" was scary by itself, but the ending makes it worse even though the family has destroyed the zombie plague. When they sit nicely in the chair and they watch TV. Marge said that they have to be happy that they didn't change into mindless zombies, but Bart interrupts them for watching TV: a guy falls on screen, and a laugh track plays only for Homer to moan, "Man. Fall down. Funny".
Homer: ...I didnt even pull the cord that time...
- Treehouse of Horror IV: "Terror from 5 and 1/2 Feet" was a homage to The Twilight Zone's own "Nightmare from 20,000 Feet", ending with Skinner putting Bart in a mental hospital due to him "misbehaving on the bus" despite Bart trying to warn them all about a gremlin he saw through the bus' windows. As a final insult to poor Bart and the psychological damage he went through, the gremlin appears in the back window of the ambulance he's in, while holding Ned's decapitated head◊ which is saying "Hidely ho, Bart!". But it wasn't a clean decapitation, as Ned's very spine was clearly hanging out of his ragged neck.
Bart: Atleast now I can get some rest...
*The Gremlin appears, holding Neds severed head*
Ned: HIDELO-HO, BART!!!!
*Bart screams in terror*
- "Bart Simpson's Dracula", which parodies Dracula with Mr. Burns as the vampire. The twist at the end being that Marge is the head vampire.
- Before then you have Bart willingly pulling a trap just to slide on it. Only to see the vampires waiting for him◊. A female vampire promptly pulls him off and pins him to the floor. We then get a quick first person view of the vampires surrounding him.
- Then Burns flies in and, though we get a little humor in him not remembering Bart's name, it quickly goes back to scary when he goes in for the bite◊. Just the way how he somewhat growls as he's about to do it.
- Vampire Bart nearly biting Lisa.◊
- The ending, where Devil-Flanders loses the case to win Homer's soul, and in retaliation turns Homer's head into a donut. If you pause during this scene and put it through slow-motion, you can clearly yet briefly see Devil-Flanders turning into a screaming skeleton as he does.
- Treehouse of Horror V: The Simpson family is infected by a mist that causes people to turn inside out. And then they break into a song and dance about it. If that's not demented enough, Santa's Little Helper drags Bart away to eat him. All set to a re-lyric-ized version of A Chorus Line: "The family dog is eying Bart's intestine...". That aside, the main plot of that short was even worse, as it involved the teachers of Springfield Elementary eating all of the students, and Marge telling them to defend themselves ("saying 'don't eat us' is up to you!") when they told her.
- The view down at the meat grinder had blood splatter fanning out from the "collection vat", immediately following an absolutely demented look on the Skinner's, the teachers', and Lunchlady Doris' faces when they began advancing on them.
Skinner: I'm going to enjoy devouring you, Bart Simpson...
- Right after becoming sane again, Homer's final line of the "Shinning" segment (parodying The Shining) serves as a nice bit of Fridge Horror: as soon as he notice he can't change the channel, he mutters, "Urge to kill... rising...".
- Same segment, the 'No TV and No Beer make Homer something something...' bit- some of the faces Homer pulls are quite spooky, and his eerie calm tone as he tells Marge 'Give me the bat!' is a little chilling. Then you factor in how many people are killed by their spouses, and this sequence can hit quite close to home.
- The 1984-esque Treehouse short where Flanders is a supreme overlord as a result of Homer messing with his toaster (he accidentally turns the toaster into a time machine and changes the future by stepping on prehistoric bugs), specifically the part where a lobotomized Moe shows Homer "you get to keep the little piece they cut out",◊ or even worse, where a lobotomized Marge says "It's bliiiiiiiiiissssss..." shortly afterwards. More generally, the nicest guy in Springfield playing the Big Brother role is unsettingly ironic.
- During the opening credits at the cemetery, we expect to see some "Amusing Tombstones", but instead we get Moe hanging himself from a tree (complete with a neck-snapping sound) and then suddenly opening his eyes, which can be disturbing. And there's also that guillotine operated by Bart.
- Treehouse of Horror VI: The A Nightmare on Elm Street parody, when Willie's tongue snakes out of his mouth and strangles Martin Prince. After Martin dies, we hear a familiar, out-of-place haw-haw from Nelson, and Lunch Lady Doris accidentally takes Martin's corpse into the kindergarten part of the school. Martin doesn't exactly leave a handsome corpse either: his bulging eyes and gagging grimace are permanently affixed onto his face.
- In that same segment, Willie's initial death in the flashback was unbelievably horrifying, what with Skinner shutting him up with "Willie, please! Mr. van Houten has the floor!", as Willie, screaming for help, burns to a crisp during a PTA meeting.
- At the end dream sequence, when Bart thinks he has finally killed Willie, he's rising out of the quick sand as a giant spider.
- Treehouse of Horror VII: "The Thing and I". Due to a discovery of the "evil gene" at Bart and his siamese twin's birth, Dr. Hibbert suggests to take the newly-separated baby who has it and lock them up in the attic. Ten years later, the kids decide to investigate this and it ends up with the other twin, Hugo, trying to "re-sew" himself to Bart. Luckily, the family and Hibbert arrive and stop this before it happens. But then, to make that moment of saving moot, it is revealed that Bart is the one with the "evil gene", and he is forced to switch with his twin's position. It's a good thing that this is only a cartoon, because, if this segment had occured in real life, Homer, Marge, and Dr. Hibbert would end up going to prison for child cruelty, Bart, Lisa, and Maggie would go to child services, and Hugo would probably get taken by scientists in the hopes of "rehabilitating" him into normal society. Does anyone even remember the "Genie" case from the 1970s?
- This episode also has Bob Dole and Bill Clinton (two contemporary Real Life people, regardless of one might think about their politics) suffocating in outer space. Completely naked.
- Treehouse of Horror VIII: In the short "Fly vs. Fly" (Whole Plot Reference to The Fly), when Bart was messing around with Homer's teleporting machine and Santa's Little Helper and Snowball get in the way, that may have been another good example of crossing the line between parody and horror. On the parody side, Bart inadvertently made the Simpsons version of CatDog. On the horror side, he also made a creature that, for the sake of identification, will be called "ButtButt".
- There's one scene, in the beginning of the episode in question, where Fox Censor (the Fox censor) proudly announces that thanks to his editing tonight's Simpsons episode is rated TV-G. But as he says this, a hand with a knife appears out of the on-screen rating icon◊ and stabs him in the back repeatedly, raising the rating with every stab (culminating in TV-666). The resulting blood splatter, following tradition, spells out the title card.
- The Homega Man, when Springfield getting nuked (for real this time) resulted in a disastrous aftermath, including the mutation of the survivors in the short's second half. There were some deleted scenes that were considered to be "too much" (mostly due to content, like Homer dancing naked on an altar at the abandoned church was changed to Homer dancing in the front row — still naked) even when the episode had Homer watching a Chris Farley/David Spade movie among the bodies of nuclear bomb victims.◊
- There is also a scene wherein Homer destroys the head of a corpse sitting in a car. If you look closely, you may recognize that this is (or rather was) Millhouse's dad...
- Treehouse of Horror IX: Bart and Lisa are transported into an Itchy and Scratchy cartoon via a supercharged remote, especially when a bunch of piranha eat most of Bart's flesh.
- In "Starship Poopers", Maggie was revealed to be an alien and the daughter of Kang and Kodos - even going through stages of alien mutation such as sprouting fangs, developing tentacles, and walking up the wall. The Simpsons go on the Jerry Springer show to try and solve the crisis, but they end up fighting with Kang and Kodos who zap members of the audience with a ray gun. At the end Marge says that going on Jerry Springer didn't solve anything and Homer adds "Let's go home!"; then, suddenly, Maggie says in a deep menacing voice "Very well. I'll drive!" and lets out an Evil Laugh.
- The opening sequence for the ninth THOH episode is the first to be a properly "halloween-ized" version of the opening sequence thanks to some purposefully screwed-up timing: Bart falls off of Homer's car and snaps his neck, then Lisa runs into the car on her bike and gets launched head-first through the garage wall, and at the end, Homer runs from Marge and Maggie in the car, as they beep the horns and he gets impaled by the hood ornament.
- "Hell Toupee" makes a classic little kids' comeback sound fearsome:
Apu: (upon realizing that Snake's hair possessed Homer) Snake? But you're dead!
Homer/Snake: I know you are, but what am I?
- Treehouse of Horror X: The last episode of the 1999 Treehouse of Horror which had the Y2K end the world and two rocket ships, the good people go to Mars, the bad to the Sun. Bart and Homer get stuck on the bad one, and at the end of the short Bart and Homer escape the rocket ship to die faster, only to suffer Explosive Decompression offscreen.
- Treehouse of Horror XI: Goldilocks' fate in the fairy-tale halloween clip has her get mauled by the three bears. She struggles to get out of the house (was locked in by Bart and Lisa, who fled just a moment before). The scene then shoots from the outside of the house and all we can hear are her screams until she dies, and we only see blood coming outside.
- Later in that segment, when the witch is thrown into her own oven, Tress Macneille provides some bloodcurdling screams that while played for laughs, can be pretty upsetting.
- Other "highlights" are Homer accidentally scalping Rapunzel, and Bart and Lisa finding the skeletonized remains of their parents' two former kids. (Who look exactly like them. Including the skulls having the same spiky shapes that are usually considered to be their hair.)
- Treehouse of Horror XII: "The House Of Whacks", when the Simpsons installed the house with Ultrahouse with Pierce Brosnan's voice, who did all the housework for them until things took a turn for the worse when it fell in love with Marge. Homer ended up in a whirling garbage disposal (splattering the kitchen with blood as a result), complete with Homer's terrified scream. Additionally, one of Ultrahouse's other voices was Dennis Miller, infamous for causing murder suicides.
- Homer actually survives the garbage disposal - but the back part of his brain gets exposed as a result for being fed head-first and stays that way for the rest of the segment. Thank God the man's head is so hard.
- In the opening sequence, when the Simpsons are going to Mr. Burns house for trick-or-treating, they're so freaked out by the "accidental" Halloween decorations that they run through the gate, which slices them in the style of an egg slicer and their pieces run all over the place. Mr. Burns did it by having Smithers electrocuted on the power line for a cheap laugh. And he calls it his lucky decoration.
- Actually, it was an accident. Burns wanted Smithers to put the decoration on the top of his weather vane so people could see it. Smithers leaned out on the ladder too far and fell, sliding down the power line and electrocuting himself and causing the chaos. Burns thought the Simpsons running off scared was because they saw the decoration. You want something scarier than that, though? The decoration coming to life and flying at the camera, complete with bat shriek.
- The ending of the Whole Plot Reference of Harry Potter, "Wiz Kids": Slithers (snake Smithers) eating Lord Montymort (Burns-Voldemort)'s corpse. As a whole.
- Treehouse of Horror XIII: This◊ is why you shouldn't get someone to return your stolen power tools for you.
- Treehouse of Horror XIV: In the "Reaper Madness" segment, Homer becomes The Grim Reaper and must kill Marge, but instead kills Selma. Despite the lack of continuity-related consequences, in the consequent "Frinkenstein" segment Homer says "I wish I was Death again. That was cool."
- "Frinkenstein" by itself was scary: Frink's dad is made into a Frankenstein's monster expy and goes on a body-part-collecting rampage.
- Treehouse of Horror XV: the end of the segment "In The Belly Of The Boss", which has a shrunken Homer regrowing while still in Mr. Burns. Then, the Simpsons' family is shown eating a fancy dinner with Homer's face covered in Burns' flesh (with Homer complaining he needs a hole for eating "and a couple of other holes too.")
- Treehouse of Horror XVI: the segment where everyone turned into what they were dressed as for Halloween, including Homer becoming a headless ghoul and poor Disco Stu, who had the unfortunate idea of dressing up as 70s-era Steve Martin, who was known for having a phony arrow through his head.
- Treehouse of Horror XVII: the end of "Married to the Blob". The poor people of Springfield gratefully rush through the door of what appears to be a new homeless shelter, and straight into the jaws of a gigantic, ravenous Homer. This gross-out moment becomes chilling social commentary considering that Mayor Quimby organized the whole thing in order to allow the newly mutated Homer to "benefit society" by cleaning up the streets.
- Treehouse of Horror XVIII: Ned turns into the devil and teaches the children a lesson using his "heck house" ride. Some citizens of Springfield are seen suffering fates appropriately suitable for the sin they're committing: Groundskeeper Willy being attacked by his own tractor for wrath, Homer bursting inside-out and turning into spaghetti for gluttony, Moe taking a stripper's money and then getting kicked in the crotch for lust, greed, and envy (the "envy" part is Moe envying the crotchless who don't have the "fortune" of feeling pain from getting kicking in the groin), and Homer again ("I thought I got killed by that magic spaghetti...") getting ground through his hammock into huge square chunks of meat for sloth.
- The Halloween episode with the play on ET. Homer smothering the alien with a pillow and murmuring "Shhshhshh" while doing so, like he's putting a child to bed.
- Also, the title card and the opening credits, where they are made out of characters from various Fox shows, with House and American Idol among others (originally Family Guy's Peter Griffin was supposed to be in there, but the scene was redone to exclude that).
- Treehouse of Horror XIX: Krusty being fed through a woodchipper in "How to Get Ahead in Dead-vertising". His constant agonized screaming, ending with a pile of an organs in the end.
- Homer strangling Prince with his own guitar (shaped like the symbol he named himself in the 1990s), then stabbing him, and breaking it over his head. The other two deaths (George Clooney getting sucked into quicksand and Neil Armstrong getting hit with a golf club after a needlessly complicated Rube Goldberg-like chain of events) were funny because of how cartoony they were in nature; this...was just sick.
- Homer's head exploding after Krusty shoots it.
- Treehouse of Horror XX: In "Don't Have a Cow, Mankind" (a "28 Days Later"-meets-"Children of Men" parody), Krusty's burgers had mad-cow disease inserted into them and turned the rest of Springfield into ravenous zombies, after eating the commercialized product. Made even creepier by the complete lack of background music.
- In the same episode, the "There's No Business Like Moe Business" segment, Moe serves Marge Homer's blood after being impaled on his beer-culturing machine. However, this segment stands out as it tries to give a canonical explanation for the non-canonical body count of the Halloween episode, namely the segment's nature as a theatrical play.
- This also happens at the end of Treehouse of Horror XXII.
- At the beginning of Treehouse of Horror XXI, Poofessor Frink points a DVR remote at himself and presses fast forward, causing him to age rapidly and turn to dust.
- At the beginning of Treehouse of Horror XXII, Homer gets his right arm stuck under a boulder, and then he can't reach his secret candy-stash. The only way to get himself off the boulder is to gorily chew off his own arm. He also ends up chewing off his right leg and his left arm. It doesn't help that this Halloween episode aired the day before Halloween (in one of the rare times since the show's Golden Age that a Halloween episode didn't have to wait until after baseball season [around November] to air).
- In "The Greatest Story Ever Holed" from "Treehouse of Horror XXXIII", Sideshow Mel getting his skeleton sucked out of his skin by the black hole.
- In the Paranormal Activity parody "UNnormal Activity", Homer consoling Lisa by stating that sometimes a horrible being from Hell haunts a family at night and then kills them.
- The Halloween couch gags are pretty nightmarish as well. How bad can they be? Let's see...
- The family runs to the couch as skeletons. As a small Shout-Out, Marge has a white streak in her hair, like the Bride of Frankenstein. (THOH III)
- The family burst out of the floor as zombies and sit on the couch. (THOH IV)
- The family run in as ghouls with severely mismatched body parts. They make it worse swapping them around. (THOH V)
- The family drop down from the ceiling one by one in nooses, Maggie included. She still sucks her pacifier, though. (THOH VI)
- The Grim Reaper sits on the couch. As the family rush in, they fall over dead, one atop another. The reaper uses Homer, who dies last, as a footrest. (THOH VII)
- The family sit down as usual. Metal helmets fall on their heads, and they are shackled in before they're given the chair (in this case, couch). (THOH VIII)
- After the Halloween opening where nearly all of the family is dead, Freddy Krueger and Jason Voorhees are shown sitting on the couch waiting for the family to show up. Freddy wonders where they are, but Jason takes it in stride and switches on the tube. (THOH IX)
- The family is shown in guises from past Halloween specials as they watch Kang and Kodos' intro. Homer is a jack-in-the-box, Marge is a witch, Maggie is in her half-alien form, and Bart has a fly's head. The only exception is Lisa, who has an axe in her head. When she asks what aliens have to do with Halloween, Maggie yells "Silence!" She then pulls out a ray gun and disintegrates her. (THOH X)
- How about the intro directed by Guillermo del Toro for XXIV? Zombies have overrun Springfield, Ralph is killed when the head of Jebediah's statue falls on him, Bart is scared out of a derelict and seemingly abandoned school by a crazed Stephen King, Homer is hideously mutated by the uranium stick he drops into his safety suit and his pursued by Carl as Blade, Alfred Hitchcock causes angry birds to attack Miss Krabappel, Chtulhu has risen and towers over the town, Maggie drives a black car around the town and kills Milhouse by knocking him off a bridge and gets devoured by a feral Blinky The Mutant Fish, and Marge has become a gigantic insect creature.
- The Treehouse of Horror XXV segment "The Others," which had the present-day Simpsons being haunted by their Tracy Ullman-era selves before dying and joining them as ghosts, had a particularly unnerving moment in which Groundskeeper Willie drags off the bodies of the (modern) Simpson kids to make stew with. When Lisa asks "Wait, who killed Maggie?" Willie has a shifty-eyed look on his face.
Even couch gags aren't safe from the occasional moments of Nightmare Fuel.
- In one couch gag, the Simpsons sit down to watch TV, when "Homer" pulls his face away to reveal it's Sideshow Bob, who then pursues Bart with a knife. The intense music doesn't help.
- Another couch gag features the Simpson family sitting down, only to discover too late that it's the lure of an angler fish (a la Finding Nemo) that devours them and swims away.
- A particularly disturbing one features the Simpson family rushing to the couch as usual, only to suffer Rapid Aging and crumble into dust.
- "Clown In the Dumps" has a couch gag guest directed by Don Hertzfeldt, and yes, it's just as weird and disturbing as all of his other shorts. Watch it here.
- "ALL HAIL THE DARK LORD OF THE TWIN MOONS."
- "ALL ANIMALS CAN SCREAM."
- "Marge's Son Poisoning" begins with a particularly nasty couch gag, wherein all the couches and seating furniture come to life, and attack the citizens of Springfield. The Simpsons are menaced and pursued by their couch, which has sprouted More Teeth than the Osmond Family. Sherri and Terri are devoured by their beanbag chair. Moe fends off the advancing bar stools and booths in his tavern. And Homer, rather idiotically, attempts to seek shelter in the local couch store, only for all the couches present to lunge and pile on top of him. Given what transpires, and the eerie music that ends it, many have wondered if this was meant to precede a "Treehouse of Horror" episode.
- "MoneyBart" features an infamous couch gag, courtesy of Banksy, where the cheery world of The Simpsons cuts back to show a dark and dreary sweatshop, with poor souls who are made to mass-produce Simpsons merchandise. Animators toil away to create cells for the cartoon, with noticeable piles of bones and toxic waste around them. The stuffing for Bart Simpson dolls is manufactured from kittens that are fed into a woodchipper. A sickly unicorn is chained and has its horn used to puncture holes in DVDs. And to top it all off, the shot cuts back to reveal the sweatshop is located inside the 20th Century Fox logo, redesigned to resemble a prison.
- The "Game Over" screen to Bart vs. the Space Mutants. Bart is thrown in jail with an expression of horror on his face.
- The Itchy & Scratchy level in Bart's Nightmare has the cat and mouse duo chasing Bart with hammers, flamethrowers, bazookas and giant butcher knives. On top of that, household items come to life and also try to kill Bart including giant out of control vacuums, exploding telephones and an oven that shoots fire.
- It may only be for about 5 seconds or so but This bumper for the Every. Simpsons. Ever. marathon can be a tad unsettling...those who can't tell, it's the Simpson family merged together into some sort of hideous hybrid...and it's looking at the viewer...and then smiles.
- The arcade game:
- Defeating the Krusty Balloon boss. It expands until it nearly fills the entire screen. Then, it explodes, taking out the platform underneath it!
- The zombies from the Springfield Discount Cemetary, then the chained ghosts that chase the Simpsons into the Krusty the Clown grave.
- Pretty much everything from Dreamland, made to represent the bowels of the worst nightmares from the family. You fight off giant saxophones, Bart-vampires that shoot electricity and Homer's gigantic bowling ball at the end. Said bowling ball also explodes when you defeat it.
- Behind-the-scenes example: In the commentary track for "When Flanders Failed", they mention how one drawing of Bart came back from Korea looking really horrifying. Bart was supposed to look beaten up, but the Korean animators went overboard and made Bart all bloody, dirty, and overly bruised. Needless to say, they didn't use such a drawing in the episode.
