->'''Peter''': I don't need to hear how my parents...\\
'''Drax''': Why? My father would tell the story of impregnating my mother every winter solstice.\\
'''Peter''': That's disgusting.\\
'''Drax''': It was beautiful. You Earthers have hang-ups.
-->-- ''Film/GuardiansOfTheGalaxyVol2''

Do you have parents? Are your parents human? Do you have one or more siblings who are not your twin/triplet/etc?

If you have answered "yes" to any of these questions, then it's entirely likely that your parents have had sex. Unless you were a test tube baby... and, even then, IVF is generally only done after couples have been trying to conceive naturally for a sufficient period of time, or are a same-sex couple lacking the opposing parts. [[HappilyAdopted Or if you're adopted]], in which case, there was still a pair of human beings that conceived you. A theoretical possibility is [[UsefulNotes/{{Jesus}} divine conception]], but we're going to go out on a limb and say that two people put Tab A into Slot B to bring you into the world.

Disgusting, isn't it?

In fiction, it's common enough to see a child react with curiosity to their parents in a PrimalScene. As they get older, however, the very ''thought'' that their parents might be getting it on is enough to send them searching for some BrainBleach.


* A recent DirectTV ad plays on this, with the son going home to be comforted by his parents after getting a high cable bill, only to see them in the middle of a group of elderly couples engaging in slow massages. Which results in the son driving away with tears in his eyes, which in turn has him driving into "a pizzeria that makes really good baked ziti."

[[folder:Comic Books]]

'''Warda:''' You're a gross old man!!\\

* ''Comicbook/{{Supergirl}}'':
** Downplayed in ''Comicbook/SupergirlRebirth''. Supergirl ''really'' doesn't like hearing her foster parents flirt when she's around (or when she is ''not'' around. She can hear them from anywhere, literally). They are not concerned about her squicked reaction, though.

'''Fred:''' What the hell kind of question's that?\\
'''Linda:''' Haven't you ever heard of protection?\\
'''Fred:''' I had a gun nearby. Didn't help.\\
'''Sylvia:''' Remember that afternoon you kind of surprised us, when your dad and I reconciled? Well, I think that's when...\\

'''Sylvia:''' Sex?\\
'''Linda:''' I was gonna say "a baby", but yeah, the other thing, too.

[[folder:Comic Strips]]
* Two characters in ''ComicStrip/{{Zits}}'' had the stories of their conceptions told to them, with horrible reactions.
** Jeremy was in his room playing "Stairway to Heaven" on his guitar (he always liked the song for some reason), when his mother mentions that he probably likes the song so much because he was conceived to it. Within minutes, he's rinsing his ears out and boiling his guitar string.
** Hector's parents let slip that a batch of blueberry muffins burned during his conception. The very sight of a blueberry muffin results in severe nausea thereafter.

[[folder:Fan Works]]

* There is a MeetTheRobinsons fanfic where Lewis [[ItMakesSenseInContext ends up swapping dating stories with his]] KidFromTheFuture Wilbur and mentions that one of the girls he dated prior to Franny (Wilbur's mother) helped him realize how much he liked kids; Wilbur comments on how disturbing he finds that. Lewis points out that he needs to like kids for Wilbur to exist; Wilbur counters "There are many things necessary for my existence that I don't like to think about." [[CrowningMomentOfFunny Lewis can't respond because he's laughing so hard.]]
* In ''Fanfic/MassEffectEndOfDays'', a human boy born to an Alliance AI and a human (ItMakesSenseInContext) hears his mother discussing sexuality with Legion. Reaction... predictable.

-->''"Today's life lesson: seeing your parents have sex is gross, even if you're a god."''
** Later lampshaded by [[TopGod Fate]]:
--->''"... and children, lest you want to [[PrimalScene see your mothers naked]], I'd turn away."''
* In ''[[https://archiveofourown.org/works/8793565/chapters/20159878 How the Light Gets In]]'', Thea is horrified when she walks in on Dean about to go down on Laurel. They're both a ParentalSubstitute to her, so it counts as this. A thoroughly amused Sara then makes the situation even worse for Thea.
-->'''Sara:''' It's been like half a year, dude. Of course they're gonna fuck tonight. Probably more than once. In different positions and everything.\\
'''Thea:''' Oh, god. Please don't talk about them ''fucking'' in ''different positions''.\\
'''Sara:''' Okay, they’ll just stay in the one position.
-->'''Dean:''' Did you think we were sexless beings?\\
'''Thea:''' Yes!\\
'''Dean:''' Oh. Right. Well, okay then. You're right. We don't have sex. In fact, we're virgins. Mary was an immaculate conception. Better?
** Sara then starts to talk about the time she [[PrimalScene walked in on her parents having sex]], only to be cut of by Laurel
--->'''Laurel:''' Oh, please don't tell the hide and seek story again. I want to have sex tonight. I don't want to think about my parents.\\
'''Sara:''' Eh, point taken.

* ''Film/MrWoodcock'': The protagonist sneaks into his mother's house and, when he realizes she's come home, quickly hides under the bed. Guess what she and her boyfriend promptly start doing?
* Crops up a few times in ''Film/KevinAndPerryGoLarge''; in one scene, Kevin walks in on his parents, and later he alleges that they've only done it once, in order to give birth to him.
* ''Film/BillAndTedsExcellentAdventure'' uses the "give him money to go get himself ice cream while we do it" variant. Also gives Ted a way to annoy Bill over the MayDecemberRomance between Bill's dad and a girl just slightly older than Bill himself. Of course, Bill is presumably also put out because his parents are kicking him out of his own bedroom to do it, which is perfectly understandable.
* In ''Film/TheSMJudge'', the protagonists are a judge and his wife. One of his enemies tries to destroy his career by publicly using their sex life against him. One tactic used by this enemy is to force their daughter to watch a video of them having BDSM sex. This makes her break all contact with her parents. Not because of the scandal or the BDSM, but simply because they had a sex-life, period. "[[http://www.youtube.com/watch?v=u9HMnSJNDrY&t=1m00s You are my parents, and parents don't have sex!]]"
* In ''Film/YouDontMessWithTheZohan'', Zohan starts sleeping with his host, which horrifies her ManChild son Michael. He only makes it worse by revealing TooMuchInformation to Michael numerous times.
* Happens in ''Film/NextFriday'' when Craig's dad Willie is taking him to his uncle Elroy's until [[BigBad Deebo]] is found. During the drive, Willie says it'll be nice to have the house empty so that he and Craig's mom can "walk around butt-naked again," then he excitedly describes the naked fun they'll be having, which Craig does ''not'' want to hear about.
* Played straight and inverted in ''Film/GuardiansOfTheGalaxyVol2'': Drax broaches the subject when the group meets Peter's father, Ego the Living Planet ("How could he make a baby with your mother? He would smoosh her!") Peter is understandably squicked, but Drax isn't fazed, explaining proudly that his own father would tell the story of his conception every Winter Solstice, and tells Peter that humans have strange hang-ups.

* "The one thing you do not want to think about while eating that at some point, your ''grand''parents had to have sex."
* "If you have a biological younger sibling whose birthday is approximately 9 months after your own birthday, then it's entirely likely that your parents had sex and conceived your younger sibling during one of your birthdays."

* Happens in ''Literature/{{Memory}}'' by Creator/LoisMcMasterBujold. Ivan freaks out when he learns that his mother has gained a boyfriend in Simon Illyan.
-->'''Ivan:''' They're old, Miles! It's, it's, it's... ''undignified''. Or something. Scandalous. She's high Vor, and he's, he's... ''Illyan''.
:: Though one has to wonder if he'd be coping better if she was seeing someone other than the Imperial Spymaster.
* In ''Film/{{Sybil}}'', the title character is described as having spent her nights until she was about ten in a crib beside her parents' bed, never being given an opportunity to leave the room while they had sex. It's considered among the many, many abuses she endures that causes her [[SplitPersonality disassociation]].
* In ''Literature/SeinLanguage'', Jerry Seinfeld says that nobody wants to visualize their parents having sex and that if he found out he was adopted, this would be great news because that would mean it was possible that his parents were just really good friends.
-->''I mean, sex is a great thing and all but you don't want to think that your whole life began because somebody maybe had a little too much wine with dinner.''

[[folder:Live-Action TV]]
* Awkwardly subverted once on ''Series/AmericasFunniestHomeVideos'' when a couple announced to their 3 children that they were going to soon have a new sibling, one of the boys (who looks to be about 6 or 7 years old) exclaims, "Way to go, '''dad'''!" and gives his dad a high-five.
* ''Series/BreakingBad'': During a fit of spontaneous sex, Walt and Skyler hear Jr. walking into the house. They try to sheepishly play it off as he approaches their room, but halfway there, he realizes what is going on, gets disgusted, and leaves.

* ''Series/That70sShow'' had an episode in which Eric [[PrimalScene walks in on his parents during sex]] (unbeknownst to them) and spends the rest of the episode entirely unhinged.

At the end of the episode, Donna tells him of a time when the same thing happened to her - [[spoiler: except they were doing it ''[[BrainBleach in the hammock]]''.]]
* ''Series/CornerGas'':
** In an episode, Brent accidentally records his parents begin to act out a sex fantasy on the gas station's security camera. Afterwards he rips the camera out of the wall and denies that it was ever there.
** Also, this conversation, when Oscar doesn't want to go to the doctor.
--->'''Oscar:''' A guy my age goes to the doctor and everyone's gonna assume he's gonna get one of those little blue pills. Everyone in town is gonna be saying how I can't get it-\\
'''Brent:''' ''[grossed out]'' Dad!\\
'''Emma:''' What's he talking about?\\
'''Brent:''' Viagra.\\
'''Emma:''' Oh, for Pete's sake! ''[{{Beat}}]'' Well, if you're going there anyway, you might as well ask...\\
'''Brent:''' ''[even more grossed out]'' Ohhh, Mom! ''[leaves]''
* On ''Series/TheBigBangTheory'', the gang has gotten a hold of one of the prop rings from ''Film/TheLordOfTheRings'' movies and are holding it together, with the last one standing getting the ring. Howard and Rajesh try to psych Sheldon out by invoking this about his beloved grandmother.

* ''Series/BuffyTheVampireSlayer'':
** In "Earshot", Buffy is inflected with demon blood that allows her to read other people's mind. She then accidentally reads her mother's mind and... well:
--->'''Buffy:''' ''(extremely outraged)'' You had sex with [[TheMentor Giles]]?! You had ''sex'' with ''Giles!?!'' On the hood of a police car?! ''TWICE?!!''
** Averted in an earlier episode, where Joyce shows Buffy her high school yearbook.
--->'''Buffy:''' Mom, I'm old enough to know that you've had sex. I'm ''not'' old enough to know that you had Farrah hair.
** And in Season Five, when Joyce comes home from a date, Buffy notes that her date didn't kiss her good night. Joyce decides to have some fun.
--->'''Joyce:''' Oh, no.\\
'''Buffy:''' What?\\
'''Joyce:''' I left my bra in the car.\\
'''Buffy:''' Mom!\\
'''Joyce:''' Just kidding! ''[Buffy sighs with relief]'' I left it in the restaurant.\\
'''Buffy:''' Mom! ''[runs upstairs, hands over her ears]''\\
'''Joyce:''' ''[calling upstairs]'' On the dessert cart!
* In ''Series/{{Blossom}}'', her parents nearly sleep together after being divorced for years. Blossom and Tony discuss it afterwards. Tony admits they just like to think their parents had sex only three times (one for each child). Blossom says she likes to think they just did it twice, and Joey was sent to Earth by aliens.
* Deliberately invoked by Frank in an episode of ''Series/EverybodyLovesRaymond''. Ray and Robert hide in their parents' closet trying to scare Frank, but Frank finds them and scares them instead by pretending to have sex with Marie.
* One episode of ''Series/ArrestedDevelopment'' has Michael convincing his mother to visit his father in a conjugal trailer. While Michael is mildly discomforted by the discussion, his brother GOB reacts with outright disgust when Michael talks to him about it. GOB is later detained against the window of said trailer during their visit.
* ''Series/WizardsOfWaverlyPlace'', played straight fairly often, but a notable example is when Alex is told by her mother that her father is her 'big cuddly bug' and finds it grosser than the idea of going out with her older brother. It MakesSenseInContext, kind of...
* Referenced in ''Series/TimeGentlemenPlease'', in regards to Christanity and the virgin birth:
-->'''Guv''': No man likes the thought of his parents having sex, but to base an entire religion around the idea that they never did is taking it a bit too far!
* ''Series/HowIMetYourMother'':
** Ted's mother and her second husband don't seem to have a problem talking about this around him, eventually leading him to lose it at their wedding.
** In a later episode, Marshall has a freakout when he sees his mother having sex. Lily tells him to calm down and that his mother is only a woman with needs, at which point he tells her that she'd been screwing Lily's father. Lily immediately throws up.
* Inverted in ''Series/GameOfThrones'', after Margery Tyrell marries King [[spoiler:Tommen]] Baratheon, she starts spreading stories of his impressive sexual prowess around town, much to Cersei's disgust.
* In ''Series/{{Psych}}'', Shawn accidentally walks in on his (divorced) parents while they are having sex. After Shawn rants about the incident, Gus insists that his parents never had sex, his rationale being that he was "a perfect little miracle" and that his sister was adopted. Later in the episode, in a spirit of mockery, Shawn introduces Gus as "Immaculate Conception" as a part of his RunningGag of always introducing Gus using bizarre names.
* In ''Series/LifeInPieces'', Tyler is horrified when Tim starts describing to his son how he thought he'd lost his virginity in high school but had the experience "disqualified".
-->'''Tim:''' We were on this couch at Uncle Dave's beach house.\\
'''Tyler:''' I don't think I want to hear this story.\\
'''Tim:''' It's time I told someone and I want that someone to be you.\\
'''Tyler:''' No! It doesn't have to be!
* In ''Series/ModernFamily'', The Dunphy children walk in on their parents having sex, they eventually realize that it's a good thing that they love each other so much and get them a lock for their door, which unfortunately has a very audible click.
* A recurring theme in ''Series/{{Friends}}'' with Judy and Jack Gellar: Ross and Monica accidentally seeing their sex tape; Monica later seeing the "live show" version; Jack cheerfully discussing the list of celebrities he's allowed to sleep with with Ross, oblivious to his son's discomfort.
* On an episode of ''Series/JoanOfArcadia'', Joan (along with her brothers Kevin and Luke) gives her parents (Helen and Will) a pass for a weekend at a spa so they can have their "married couple" weekend - which she doesn't want to know the definition, or the details, of (she's freaked out enough when Helen reminds Will about playing "strip Scrabble").
* Mild example in Series/CallTheMidwife: Tim gets grossed out by his parents kissing.
-->'''Timmy:''' Do you have to do that?\\
'''Shelagh:''' No, but it bothers you and that keeps us entertained.
* On ''Series/{{NCIS}}'', Tony [=DiNozzo=] gets this when he walks in on his father doing it...in Tony's bed.

* Notably averted in Music/TheLonelyIsland song "Mother Lover", where a pair of friends played by Andy Samberg and Justin Timberlake go into detail about their plans to seduce the other's single mother as a Mother's Day gift.
-->''We both love our moms, women with grown women needs\\
I say we break em off, show em how much they really mean''

* Lucie Miller in the AudioPlay/BigFinishDoctorWho audio ''Death in Blackpool'' has similar feelings about her {{Parental Substitute}}s, the Doctor and Auntie Pat (who aren't):
-->'''Lucie:''' What would they be doing in a cupboard?\\
'''Billy:''' You'll ''never'' guess...\\
'''Lucie:''' Oh God, no.\\
'''Billy:''' Worse than that.\\
'''Lucie:''' What could be worse than ''that''?

[[folder:Stand-Up Comedy]]
* Creator/JeffFoxworthy had a few short bits on the subjects. In one routine, Jeff recalls that when he first found out what the physical act of sex entailed, he couldn't imagine his parents doing that to each other.
-->'''Jeff Foxworthy:''' I could never picture my mother screaming "give it up, you pot-bellied stallion!"
* Comedian Christian Finnegan ends a bit on sex with the knowledge that your parents had sex. On a live recording, he goes into very explicit detail about making love with "your parents" as the subject. By the end, some audience members can be audibly heard ''begging'' him to stop.

[[folder:Video Games]]
* In ''VideoGame/MassEffect3'', Liara's reaction to her father ([[spoiler:[[CoolOldLady Matriarch Aethyta]]]]) telling her that her mother had a "hell of a rack" is a grossed-out "You don't need to tell me ''everything.''"

This scene is revisited every time the player unlocks a new class, with the ending revealing that [[spoiler:their parents weren't having sex, but getting drunk and high and arguing over you]]. At the end of the game, [[spoiler:[[BigBad Mitch Conner]] reveals he orchestrated the plot out of revenge for his father, who got "fucked".

-->'''Ruby:''' ''[disgusted at the thought of that conversation]'' Eww, gross.

'''Old Man Death:''' Heh, even today your grandmother is a ''remarkable woman''.\\
'''Zeuxippe:''' ''Eeew!'' ''Grand''pa!\\

-->'''T-Rex:''' MOM did that?
* One early strip of ''Webcomic/KevinAndKell'' has Rudy walking in on his parents roleplaying ''Literature/LittleRedRidingHood''. To expand, they're a [[InterspeciesRomance wolf and a rabbit]], though the wolf was playing Lil' Red.
** Ralph's head literally imploded when he learned the picture of the 'hot babe' he had leaked onto the internet was of his mother, back when [[IWasQuiteALooker she was quite the looker]].
* In ''Webcomic/AndShineHeavenNow'', [[Manga/{{Hellsing}} Integra]] is horrified at the thought of hearing her father's teenage exploits as told in a novel.

* In ''WebComic/{{Shortpacked}}'' Mike basically banked on this trope to try to get Amber to leave him once and for all, by manipulating events so her mother had sex with the sex addict Jacob, recording it, and playing the tape for Amber. While Amber ''did'' throw up after hearing the tape, she later expressed disbelief that Mike thought she'd leave him because she heard her mother (who's middle aged and had been abused in her marriage) ''finally'' have a fulfilling sexual experience. As for the vomiting? [[spoiler: Turns out that was MorningSickness.]]
* Goes several ways in Webcomic/QuestionableContent:
** Subverted by Marten, who is completely unable to be surprised by his parents, one of whom is a fetish model and one of whom runs a gay nightclub. He mostly doesn't want details, and does get weirded out when he finds out his girlfriend had masturbated to some of her photos.
** Clinton is utterly grossed out when he stops by his mom's house and finds her with a 20-something guy who he used to tutor. His sister, Claire, is enthusiastic.

* {{Inverted}} in ''WesternAnimation/AmericanDad'' in "Bullocks to Stan", where Stan's boss is dating his daughter.
