History Recap / TheSimpsonsS7E6TreehouseOfHorrorVI

* ThirteenIsUnlucky: The story of "Nightmare on Evergreen Terrace" starts "on the thirteenth hour of the thirteenth day of the thirteenth month" with a meeting to [[LampshadeHanging discuss the misprinted calendars]] bought by the town.
-->'''Homer:''' "Oh, lousy Smarch weather."

* TheEndOrIsIt: Subverted in "Nightmare on Evergreen Terrace": Right after Lisa says [[SequelHook that she doesn't thinks Willie is gone for good]] Willie walks up to them and makes scary faces -- but now that he no longer is in the dream world, [[VillainDecay he's a whole lot less threatening]] to a comically humiliating degree.

* YourMindMakesItReal: Towards the beginning of "Nightmare On Evergreen Terrace", Bart thinks the whole thing was AllJustADream, until he pulls down his comforter showing his scars from Willie's attack. Later at school, Lisa and other kids show signs of attacks by Willie. And when Willie kills Martin, we see Martin gasping and convulsing in real life before dropping dead.

* AmbiguousSyntax: "'Do not touch Willie.' Good advice."

* OnlySaneMan: In ''Nightmare on Evergreen Terrace'', Homer is the only one to vote for the free fire extinguisher refills.

* RealityEnsues:
** In "Nightmare on Evergreen Terrace", Bart and Lisa try to stay awake so Willie (playing a Freddy Kruger {{expy}}) won't get them in their dreams, but know it's impossible. Bart volunteers to go into his dreams to combat him while Lisa stays awake to wake him if he runs into trouble. When he does and calls for Lisa to wake him, Lisa appears in his dream to do so. Bart points out the obvious problem there, which Lisa claims she was just resting her eyes before realizing her mistake.
** In "Homer³", Homer ends up in a literal 3rd Dimension realm and accidentally causes a black hole. Bart tries to save him but they're on the opposite ends of the hole with Bart telling Homer he'll have to jump. Thing is, the hole is way too big for that idea to even be possible and sure enough when Homer attempts it, he promptly falls into it being nowhere near close enough for Bart to grab him.

* AttentionWhore: In "Attack of the 50-Foot Eyesores", the ad company executive claims this is true of the giant advertising mascots and advertisements in general, and that they need attention to live; if people stop paying attention to them, they lose their power. (And indeed, isn't that how advertising works?) Of course, it's hard for the townsfolk ''not'' to give attention to a group of monsters destroying the city, but Lisa and Paul Anka are able to convince everyone to ignore them.

* AluminiumChristmasTrees: When Homer is trapped in the Third Dimension, he asks everyone if they saw the movie ''Film/{{Tron}}''; no one did[[note]]except for Chief Wiggum, though he quickly denies it[[/note]]. This caused many fans to believe that Homer made up the film until the release of ''VideoGame/KingdomHeartsII'' over a decade later, which includes a world based on the film, and then ''Film/TronLegacy'' in 2010, which caught many ''Simpsons'' fans by surprise.

** A 3-dimensional cone hits Homer, which he throws into the floor and accidentally pierces the fabric of the space-time continuum, causing it to form a worm hole and collapse into black hole.

* UnwittingInstigatorOfDoom: Homer does this ''three times in the same episode'':

** A 3-dimensional cone hits Homer in the butt, which he throws into the floor and accidentally pierces the fabric of the space-time continuum, causing it to form a worm hole and collapse into black hole.

* UnwittingInstigatorOfDoom: If Homer hadn't messed with the thermostat, Willie wouldn't have died and sworn vengeance against everyone.

* WritersCannotDoMath: Averted. There are some very clever math jokes in "Homer&sup3". There is also an ASCII formula, which, when decoded, says, "Frink rules!".

** Even when Willie bursts into the PTA meeting screaming for help, Kirk Van Houten would rather grumble about school cafeteria menus. Earlier, the parents also turned down the replacement of a broken door knob costing 12 dollars and a free refill of an empty fire extinguisher, implying that they turned them down the last time as well, either of which could've saved Willie's life and prevented the events of the segment from taking place.

* RogerRabbitEffect: The episode ends with [=3D=] Homer being transported into the real world (if you can call Los Angeles real). If you pay attention to the people around him, they seem very well aware that the strange, yellow man walking down the sidewalk isn't normal. None of them seem to do anything more than stare, however, and Homer freaking out over being in the real world is cut short when he goes inside an erotic bakery.

-->'''Homer''': (leans into frame) We'll be right back. ([[{{Troll}} shit-eating grin]])

* WritersCantDoMath: Averted. There are some very clever math jokes in "Homer&sup3". There is also an ASCII formula, which, when decoded, says, "Frink rules!".

* UngratefulBastard: The Lard Lad doesn’t calm down when his donut is returned, but rather continues the rampage.

* DeathByInaction: Because the parents sat there and did nothing, Groundskeeper Willie burns to death.
