History NightmareFuel / KingOfTheHill

* In ''Megalo Dale'', Dale is hired to do some exterminating at the Mega-lo-mart on Hank's good word, but as he starts looking into the supposed infestation, he becomes convinced it's actually Chuck Mangione living in the store. Hank, Bill, and Boomhauer end up going to the Mega-lo-mart at night to help Dale deal with the actual rat problem at the store. Hank eventually gets tired of trying to talk sense into Dale and tries to call his rivals into doing the job he was supposed to do. Then, suddenly, the music stops, and Hank doesn't notice that something has just severely scared the guys into a state of shock. Hank says the phone isn't working, and then he sees what the guys have: someone has just blocked off all the exits with vending machines. Then they start to hear trumpet music and the lights systematically go out.

* Bobby's subplot in "King of the Ant Hill." He collects a queen ant in a jar, smells her pheromones and is compelled to obey her commands to bring her sugar. Later she orders him to return her to the lawn and when he initially refuses she says ''something'' that makes him back down. When he does return her to the lawn she orders the entire colony to swarm him. They cover him completely ([[EyeScream even running over his eyes, as seen in a POV shot]]) and he begs Hank and Dale to help, terrified to move and risk getting stung.

* "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.

* Peggy's hellish nightmare in "Are You There God? It's Me, Margaret Hill". In the episode, Peggy pretends to be a nun at a Catholic school in order to become a full-time teacher, only to find out how she may have inadvertently damned her students to Hell by failing to teach them properly. In her nightmare, a demonic version of Monsignor Martinez breaks into the classroom and opens a portal to Hell. He pushes two or three children into the fire before Peggy pleads with him to stop, confessing her lies. There is a HopeSpot when the flames extinguish... before Hank steps in and fixes the propane tanks being used to make the heat.

*** The scene when Luanne hears noises behind one of the doors in Trip's house, and a crazed pig comes at her and scares Luanne out of her mind.

** Even worse, the episode is [[PopCultureUrbanLegends said to have had its original airing end with Trip's bloody corpse sliding back on a hook behind Peggy and Luanne. Subsequent airings removed this scene for obvious reasons, Fading out before the body was shown.]]

** In the recovery that follows, however, Peggy goes into a sharp depression with time thanks to being almost entirely immobilized and helpless, besides her toes. It elicits a very AdultFear that a completely unforeseen consequence could potentially ruin your life, and she's damn lucky she gets to recover in the first place.
** Near the end, everyone is hit with a moment of AdultFear when G.H. ''stops'' crying. This causes Hank and Cotton to panic and run inside, but the moment ends when it's revealed G.H. stopped crying because Peggy rocked him to sleep with her toes.

* In "Hillenium", Hank comes ''very'' close to dying when he doesn't ventilate his garage while putting varnish on a grandfather clock he'd bought. We see him progressively inhale more and more, until he is basically drunk on the fumes, giving a babbled "Oooops..." when he brushes varnish over the entire face of the clock, before falling to the floor of the garage (and thankfully not apparently getting a head injury from that), drooling and swiftly slipping into unconsciousness. It gets worse though, when Peggy announces she's taking Bobby and Luanne Christmas shopping, [[AdultFear completely unaware her husband is in danger]]. Hank thankfully just has a messed up dream involving Whack-A-Mole and his fears over Y2K that led to all this, then manages to regain consciousness and drive his mower out through the garage door, just as the family arrive home. Still, [[FridgeHorror imagine if Hank hadn't done that and the family didn't check on him until it was too late...]]

*** The scene when Luanne hears noises behind one of the doors in Trip's house, and a crazed pig comes at her and scares Luanne out of her mind.

* "Jon Vitti Presents Return to La Grunta" contains an unusual example of violent sexual harassment for this type of show. Hank gets Luanne a job at a golf course, because she wants to earn money for herself. At first she's excited by her new independence and pleased with the generous tips. But it quickly becomes apparent to Luanne, who is usually an InnocentFanserviceGirl PlayedForLaughs, that one customer has more perverse thoughts on his mind, and doesn't hesitate to act on them (to the apathy or amusement of his friends). It's a darkly realistic depiction, especially given her child-like naivete; she just freezes with a scared expression whenever he starts groping her. When she gets back from her job, she suddenly HatesBeingTouched to the point where a twelve year old tapping her on the shoulder to get her attention makes her blow up. The worst part is probably when Luanne tries to dress in unflattering clothes on the job to stop drawing attention, to no avail. [[LaserGuidedKarma Hank manhandled the guy when he found out]] and presumably reported him, but it doesn't detract from how uncomfortable the rest of the episode was.

* "Pretty, Pretty Dresses" is one of the most disturbing episodes of the series.
** 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.
* "Hank's Cowboy Movie" has a brief moment that gives us the ''[[SarcasmMode delightful]]'' image of a monkey biting off and swallowing the head of a live mouse.
* "Manger Baby Einstein" shows the destruction of the Manger Babies at the hands of Dale, their stuffing exploding from their seams in a dryer as Luanne screams in horror.
* "Dream Weaver": Dale's daydream of everyone laughing at him. It's not scary per se, but some of the distorted laughing faces during it, especially Hank's, are pretty [[https://knowyourmeme.com/photos/84858-happy-hank freaky looking.]]
* "Bobby Goes Nuts": Hank getting kicked by Bobby after he smacked Bobby a few times. The scene afterwards is a little uncomfortable with the dialogue.

** In the recovery that follows, however, Peggy goes into a sharp depression with time thanks to being nigh-completely immobilized. It elicits a very AdultFear that a completely unforeseen consequence could potentially ruin your life, and she's damn lucky she gets to recover in the first place.
