History NightmareFuel / KingOfTheHill

* The cliffhanger at the end of "As Old as the Hills", where Peggy opts at the last minute to skydive after her reservations previously once she feels jealousy from Didi having a child. [[OhCrap Then her parachute fails to deploy.]] The episode ends with Hank watching her, screaming at the top of her lungs, slamming into a field in the distance before he turns to the screen in horror. [[spoiler: Thankfully the beginning of the next episode reveals she landed in soft mud, but this still broke her back and it actually takes her several episodes to recover.]]

* Hank's BigNo in "Luanne's Saga" on seeing Boomhauer kiss Luanne.

* "Pigmalion": the HalloweenEpisode, in which pork and [[LiteCreme pork-product]] mogul Trip Larson (voiced by Creator/MichaelKeaton) falls in love with Luanne, tries to turn her into the product's mascot and tries to turn them into pork products on a ConveyorBeltODoom, all because of his schizophrenia. Luanne gets out okay. Trip, however, [[KarmicDeath ended up hacked to pieces]] after an electric shock clears his schizophrenic mind -- and makes him realize too late that he's on the kill line.

* Hank's "BWAH!" in "Luanne's Saga" on seeing Boomhauer kiss Luanne.

** The anger of his anger management classmate Big Jim, especially when he starts yelling at Dale before barking and frothing at the mouth like a dog, freaking everyone (including Hank) out, which causes him to suffer a stroke and die. He died angry, indeed.
** Later at Jim's funeral, Hank remembering all the times he's gotten angry and realizing the inevitable outcome if no progress is made.

-->'''Hank:''' That's a clean burning Hell, I'll tell you what!

King Of The Hill is a pretty laid-back cartoon, but it is made by the same guy who introduced the world to ''WesternAnimation/BeavisAndButthead'', so there are some moments that come off as nightmarish.

* Hank's "BWAH!" in "Luanne's Saga" on seeing the "Luannehauer" pairing.

-->'''Hank:''' That's a clean burning Hell, I'll tell you hwat!

-->''"That could be '''''me''''' lying there..."''

-->'''Peggy:''' Honey, Trip had a mental breakdown and is now a sausage. That's ''not'' a better place.

* When Bill becomes interested in a dog-dancing contest in "Dances With Dogs", he [[TooDumbToLive attempts to train a savage Rottweiler]] that attacks him almost instantly. Even when the dog is sedated, we see its dream of mauling Bill.

** Bill's depression hits its apex and he starts trying to take his own life. After his bungled attempts do nothing other than annoy the others, Hank tells Bill that Lenore is never coming back and smashes all of the "presents" he had gotten for her, causing Bill to snap and lose all feeling.\\
\\
The next day, Hank returns to Bill's house and finds Bill dressed in drag and adopting Lenore's personality. He keeps up the act until the Christmas party, in which Peggy tried to invite the real Lenore to the party, who declined the invitation over the phone.\\
\\
Once the disturbed guests start heckling Bill, Hank puts on a dress to try and ease the tension, causing Bill to run outside in tears. Hank pretends to be Lenore and tells Bill why "she" left him, allowing Bill to get his closure. Everything ends on a good note, but it still doesn't ease the creepiness in the middle.

* Chip Block the ventriloquist dummy can be nightmare fuel to those who have a fear of said dolls, as it looks genuinely creepy. Bobby spinning its head around while introducing it to Dale doesn't help. Not to mention Dale's (exaggerated) flashback shows him as a kid receiving the same dummy as a Birthday present, with everyone (including the dummy) laughing evilly is rather disturbing. And the Bobby(!)dummy is rather creepy too, if not just for the uncanny valley.

* "Pretty, Pretty Dresses" is probably the most disturbing episode of the series.
** Bill's depression hits its apex and he starts trying to take his own life. When that doesn't work, Hank tells Bill that Lenore is never coming back and smashes all of the "presents" he had gotten for her, causing Bill to snap and lose all feeling.\\

* The Propane explosion at Mega-lo-mart at the end of season 2.

** During the episode itself, Bobby begins using Luanne's practice female dummy head (the titular "Plastic White Female") as a practice tool, but it soon becomes an obsessive crutch. On a stormy night, Bobby breaks the lock on the cupboard that Hank stowed the head in. We see Hank becoming increasingly angry, and his immediate response is to take the head by force and saw it in half, despite Bobby and Luanne's protests to stop.

* The Mega-lo-mart bomb at the end of season 2.

** Later at Jim's funeral, Hank remembering his angriest moments throughout the series via flashbacks and realizing he may suffer the same fate if he doesn't control his temper.

** Later in the same episode, the flashback montage of Hank's anger throughout the series.
** ...All of which are nothing compared to the anger of his anger management classmate Big Jim, especially when he starts yelling at Dale before barking and frothing at the mouth like a dog, freaking everyone (including Hank) out, which causes him to suffer a stroke and die. He died angry, indeed.
