Brain Bleach/Live-Action TV/Mystery Science Theater 3000

Mystery Science Theater 3000 is rife with aghast reactions to events on the screen. Examples include: "Tom: I'm being punished for something, I know it. What did I do? I DIDN'T ASK TO SEE THIS MOVIE!"
 * Eegah

"Crow: Mike, I'm going to ask you to kill me now... Mike, please kill me."
 * I Was a Teenage Werewolf

"Crow: How can we make a sketch when we have to watch...uh...uh...uh...MANOS! THE HANDS OF FATE..."
 * Manos: The Hands of Fate

"Tom: Mike, if I run out of vomit can I have some of yours?"
 * Hobgoblins

"Crow: To be dead...To be nothing...To watch Neptune Men no more..."
 * Invasion of the Neptune Men

"Crow: [mocking the narration] There was no dignity for anyone who worked on this film!"
 * Monster a Go-Go!

"Crow: Now I need years of powerful Adlerian therapy. Tom: They hung his head! This is worse than Seven."
 * "Robot Rumpus", a Gumby cartoon short preceding The Screaming Skull, after the Bots seeing a robot's head hung on a wall:

"Servo: Smolkin's naked sometimes, Mike. Mike: (cringing) Damn you, Servo!"
 * Boggy Creek II: And the Legend Continues..., and the reaction to the farmer's poo-stained trousers, ending with Tom's panting.
 * And in The Undead, Servo sadistically shares something about Crusty Gravedigger Smolkin.

"Mike: (disgusted) What gets into some civilizations?!"
 * There's also Mike and the 'Bots' cries of horror whenever the camera pans down during Prince of Space, revealing that the Chicken-Men of Krankor are going commando.

"Joel: BABY OIL?! AAAAAAAAAAAHHHHH!!! Hoyt Axton: (singing the background music) My, my, my, my, Mitchell... Crow: My, my, my, my GOD no!!"
 * And during the sex scene between Linda Evans (yay!) and Joe Don Baker (oh sweet merciful Bahamut) in Mitchell:

"Tom: Joel, I demand you take my head off."
 * The sequence begins with a bizarre shot of a bulge slowly sliding down the inside of Joe Don Baker's trouser leg. It turns out to be his snubnosed Colt revolver, but for a second...
 * Even worse, the implication in context is that it was dislodged by Joe Don Baker's...no.
 * Attack Of The The Eye Creatures. The final scene with the the Covert Pervert Scrappy Military Officers:

"Crow: Wh-wha-WHOA! That took my soul, right there!"
 * Soultaker. Robert Z'Dar's crotch is thrust in Crow's face.

"Servo: I don't know how, but I just became sterile! Mike: (utterly defeated) Oh my, what a...what a handsome man."
 * The Giant Spider Invasion. The cast screams upon seeing filthy Wisconsin hick Dan Kester in his stained pajamas.

"Mike: Aaaaand the movie ramps up the repulsion. Crow: Yeah. This movie hates us, doesn't it?"
 * Making matters worse, Dan then chases his nubile niece around a table threatening to spank her.

"Crow: This is supposed to be an epicac, right?"
 * Space Mutiny. Leah's seduction of pudgy, balding middle-aged guard Murray, screaming when he takes off his pants.

"Servo: Please, Mike, cover my eyes. Crow: That's it. I'm gonna be a monk. (Crow and Servo make gagging noises as they kiss.)"
 * The Sinister Urge, written by Ed Wood, featured a scene in which porn director Johnny Ride gave mannish porn mogul Gloria Henderson a long kiss.

"Crow: Now, wait a minute -- how did she turn into a bat? The only contact she had with him was in the hotel, and... [long, awkward pause] ...Oh my God. Tom: Gahh! Crow: Oh my God! I get the shower first! Tom: No, me first! Mike: Urgh."
 * It Lives by Night. Comes into play at the end of the movie along with a healthy heaping of Fridge Horror:

"Servo: Turn it off! Turn it off! Turn it off!!!"
 * Not all the examples come from the experiments. One host segment of Bride of the Monster featured Tom Servo dressed in a nurse's outfit while Joel used an invention to see what Crow was dreaming of: a sexual fantasy with Tom dressed in the same nurse's outfit. Tom's reaction was identical to VanDorn's in Hardcore.

"Mike: So...we can contact the Mads when we like...but...I don't think I'm going to do that anymore."
 * A similar occurrence happened when Mike decided to contact the Mads without permission, resulting in them stumbling into a disturbingly domestic, loving scene that left Mike, Crow, and Servo with their mouths widely agape.

"Crow: Part of me will never be back. Part of me is gone forever."
 * The Horror of Party Beach. The bots' reaction to Mike dancing in tiny bikini briefs.

"Kevin: "I remember now that hillbilly... teenage..." Mike: "Oh, no!" Kevin: "I don't want to tell the name, because some of you freaks out there will try to find that film. And that's just wrong! I don't remember how we got it, but we got it out of the place as fast as possible. It was about child brides, and it was..." Mike: "That should give you a clue about the title." Kevin: "Stop! Psshh! Psshh!" Kevin: "And it was all said in crackabill, like they actually hired people who lived there rather than actors. And I had a good cry after that one. And then a shower." Mike: "You should take a shower right after that.""
 * The tradition continues on in Riff Trax.
 * For example, in the Riff Trax of Attack of the Clones, Kevin tells Mike during the Greasy Spoon scene regarding slovenly cook Dexter, "Mike, I invite you to think about his underpants." Mike understandably reacts in horror: "Why, Kevin?!" Kevin subverts the trope by telling him that so long as he's thinking about Dexter's underpants, he's forgetting the rest of the movie. Mike's response. "[sigh of relief] You're right. Ah, his underpants..."
 * Special Mention goes to Child Bride. When watching this movie, the producers decided that they would never use it in their show. There's a hilarious moment in one interview.
