* [[https://www.youtube.com/watch?v=6Twylp9sJcg Sheldon's fake smile with his eyes wide open and showing all of his teeth]] was the page image here for a ''long'' time. It still has a home on TVTropes, over at 'TheUnsmile'.

* Something about Leonard's mother's voice is a bit chilling. She sounds how a female version of [[Literature/IHaveNoMouthAndIMustScream AM]] would. Think of Leonard's childhood. She is really is comparable to the likes of [[VideoGame/BioShock2 Sofia]] [[PsychoPsychologist Lamb]] and [[Franchise/SilentHill Dahlia]] [[SinisterMinister Gillespie]]. The way she {{Mind Rape}}s [[https://www.youtube.com/watch?v=nRoxCqCd77E Penny with that smile on her face]]: that's like Johan Liebert from ''Anime/{{Monster}}''... forget suicide, it's a wonder Leonard didn't turn into a serial killer!

* Howard's mother. We never see her, she [[NoIndoorVoice always shouts]], and according to Howard, he doesn't live with her, ''[[https://www.youtube.com/watch?v=7EBN0xlUGOg she lives with him]].''

* Howard's mother. We never see her, she [[NoIndoorVoice always shouts]], and according to Howard, he doesn't live with her, [[https://www.youtube.com/watch?v=7EBN0xlUGOg ''she lives with him'']].

* Stuart watching Howard and Bernadette while they sleep us just plain chilling.

* [[StepfordSmiler Bernadette]]. [[https://www.youtube.com/watch?v=8Rv8ph4oXEM Just Bernadette]]. At one moment, she would be cute, sweet, cuddly, the next moment she would use her scary voice to force you to do things.

** Far more horrific? Goodness, no. [[HouseOf1000Corpses The movie]] they discuss watching is 100% real. Sweet dreams.

* In Season 5, it's never shown what exactly was [[https://www.youtube.com/watch?v=W7JvTtpOjU0 crawling around]] inside the chair Penny picked up off the street. Its size, shape, and movements seem to indicate a mouse or a small rat, which would be scary enough, but the fact is [[NothingIsScarier we never find out for sure]].

* [[ShoutOut The]] [[TheTimeMachine Morlock scene.]] A dream within a dream, both with Morlocks [[https://www.youtube.com/watch?v=eKt9OIED57E that attack Sheldon no matter where he goes with the Time Machine]].

* In "The Hot Troll Deviation", Howard, using a recording of Sheldon saying "Penny", tricks Penny into opening the door by imitating Sheldon's signature knock. Penny then states she wouldn't have opened the door if she knew it was him after he gave him a teddy bear that turned out to contain a ''webcam''.

** The worst part is that its completely PlayedForLaughs, even when Leonard actually shows how much his mothers behavior upsets him. On top of that, [[https://www.youtube.com/watch?v=AMUBvRvzZtk his mother KNOWS that her behavior is abnormal and directly harmful to the development of her children, being an expert psychologist, but she has no interest whatsoever in changing]].

* In Season 5, it's never shown what exactly was [[spoiler: crawling around inside the couch Penny picked up off the street, and later picked up by Howard and Raj.]]
** [[https://www.youtube.com/watch?v=W7JvTtpOjU0 Given the characteristics of the]] [[spoiler: bulge and its movement]], probably a [[spoiler: mouse or other small rodent.]] Still scary?
** I assumed it was a rat. While pet rats are cute, [[http://upload.wikimedia.org/wikipedia/commons/f/f4/Ratking.jpg sewer rats are not]].

* In "The Hot Troll Deviation", Howard, using a recording of Sheldon syaing "Penny", tricks Penny into opening the door by imitating Sheldon's signature knock. Penny then states she wouldn't have opened the door if she knew it was him after he gave him a teddy bear that turned out to contain a ''webcam''.

* The two HUGE rats that attack Raj in "The Expedition Approximation."

* Literally, and in-show: for Penny (and Leonard), it's Howard and Leonard's explanation of how Sheldon might reproduce.

* When Howard digs out his childhood set of magic tricks from the closet, he discovers the "dove in the pan" trick [[{{Squick}} still contains the dove.]]

* Bernadette's fake laugh is one of the most terrifying moments in the series so far.

* When Howard is going into space the gang is sitting in the apartment watching the launch together. It's a heartwarming scene. It becomes Nightmare Fuel when you think about the Challenger disaster and consider what if it was your own friend/spouse in Howard's place.

* Howard's mother. We never see her, she [[NoIndoorVoice always shouts]], and according to Howard, he doesn't live with her, ''she lives with him''.

%%* The Chair of Death from "The Infestation Hypothesis".
* When Sheldon got even with Leonard for a scare prank. Not the prank itself, but the fact that the audience didn't see that coming.
* [[StepfordSmiler Bernadette]]. Just Bernadette. At one moment, she would be cute, sweet, cuddley, the next moment she would use her scary voice to force you to do things.

* Sheldon's dream at the end of "The Santa Simulation". Sweet moment with Santa: Awww. Santa turns it around and shoots up the apartment with a cannon... Um, yeah, definitely a nightmare. Sheldon's face at the end when he wakes up shows the poor guy is obviously terrified and there's no ending joke to diffuse the tension for the emotionally confused audience. The audience that just saw Santa. Try. To. Kill. Sheldon.
* The episode when Howard eats peanuts in order to keep Leonard away from his apartment for a surprise party. Howard's swollen face was TERRIFYING.
* Sheldon gets 25 cats replace Amy in his life. The episode is hilarious and cute but this line is jarringly disturbing.

* In the episode where the guys fight over a prop of [[Film/TheLordOfTheRings the One Ring]], Sheldon has a nightmare where he gets it and [[BodyHorror becomes]] [[MythologyGag Gollum]]. It isn't a pretty sight, and is currently the page image. [[SarcasmMode Sweet dreams]].

** Given the characteristics of the [[spoiler: bulge and its movement]], probably a [[spoiler: mouse or other small rodent.]] Still scary?

* Raj trapped in Mrs. Wolowitz's house.

* When telling stories about what life would be like if they never met Sheldon, Howard's story involves [[{{Film/Psycho}} his mother being dead and it's unknown if she died naturally or Howard killed her. He still has her body and treats it as if she is still alive.]]
