Isn't it cute when a kid knows more than you'd think? Isn't it even cuter when they know more than you'd think about something that you'd prefer no kid knew at all? Especially if the kid is too young to be in the Competence Zone. It's a pretty sure-fire way to get a laugh, especially if adults have spent the whole episode trying to keep the kid from finding something out, and the kid knew it all along.
To anyone young enough to understand or who can remember what it was like to be young, it's funny because the child shows a complete disregard for the unsaid treaty between children and adults: Kids can learn things as long as they pretend they haven't and don't ever mention it. It works on numerous levels.
This trope often isn't exploited in full in live action media, because if a child actor actually says the darndest things, the Moral Guardians will complain. Instead, they say mildly darned things. Other media will exploit this more fully.
See also The Talk. For a more general example of kids talking outside of their expected age range, see Little Professor Dialog. If the kid is performing a song they know that wasn't... written for a kid to sing, then it's Age-Inappropriate Art. Sub-Trope of Troubling Unchildlike Behavior. Compare and contrast Not in Front of the Kid.
- Quaker Chewy Granola Bars used to be advertised as being able to stop children from saying the darndest things. One of their ads had a little boy walking up to a bride and informing her that his mother can't believe that she (the bride) wore white.
- A popular Norwegian advertisement shows a mother awkwardly trying to explain to her son that his goldfish, Doffen, is tired and needs a vacation. Cue the boy's sister showing up asking what's going on, the boy casually remarks "Doffen has died" and leaves the room.
- An ad shows a child meeting his dad's boss, and after a moment saying "Daddy, his nose isn't brown."
- This Volkswagen advert.
- Much of the jokes in Crayon Shin-chan are of this type. Though mostly in the American dub. In the original dubs, all kids but Shin-chan (And a bit of Nene, the preschool equivalent of a Covert Pervert) are perfectly innocent, and (especially in the manga) it's hinted that Shin-chan doesn't know what he's talking about most of the time.
- Kirimi Nekozawa from Ouran High School Host Club. For some reason, her minders decided to read her shoujo manga, which leads her to say things like "There's debauchery going on here, isn't there?" In the manga (and the English dub), she goes so far as to call the Host Club a "reverse harem."
- The Magical Girl Lyrical Nanoha Lyrical Almanac Gag Series in Megami Magazine uses this for a punchline in one comic◊ as Vivio somehow misinterprets her Fate-mama's having her own place to return to as, well...
Vivio: Wait, does that mean Fate-mama... is a gigolo?
Fate: What!? No!
- The backstory for Mobile Suit Gundam Wing's Duo Maxwell gives him a non-swearing example of this. During a conversation with the priest and nun who raised him, he says he doesn't believe in God, but he does believe in the God of Death, because as he puts it, "I've never seen any miracles, but I've seen lots and lots of dead people!" The nun admonishes him gently, but the priest laughs and admits the boy has a point.
- A regular source of humor in the Gag Dub of Ghost Stories.
- Zig-zagged with the Nyan-Nyans from Fushigi Yuugi. Yes, they are Physical Goddesses and Really 700 Years Old, but for the major part of the series they look like little girls no older than 10 and have the mentality of such. But then they open their mouths...
Nyan Nyan:[to Nuriko, as her sisters heal Miaka, Tamahome, and Hotohori] Let me heal you!Nuriko: Thank you, but I'm not hurt...Nyan Nyan: I'll heal your perversion!Nuriko: [punches the offending Nyanyan into the stratosphere]Nyan Nyan: Ai yaaaaah!!!
- Persona 4: The Animation:
- Right after the school festival, Nanako gives us this gem, courtesy of the festival's fortune teller who is really Margaret.
Nanako: Man whore! She said you're one big man whore!
- And later in that same episode, the boys are caught "peeping" on the girls during the hot springs episode.
Nanako: Big bro... are you and Teddie... horny?
- Right after the school festival, Nanako gives us this gem, courtesy of the festival's fortune teller who is really Margaret.
- In episode 5 of season 2's Yuru-Yuri, while waiting for Himawari, Sakurako makes another A-Cup Angst joke about her. Kaede, Himarwari's kid sister, arrives at the front door and asks if she hates boobs. Sakurako says she doesn't, and then Kaede innocently says she'll share her boobs with Sakurako. Later, she brings some milk for her in an attempt to increase her bust size. Sakurako holds back hitting her since she doesn't know any better.
- In episode 10 of Bokura Wa Minna Kawaisou, Chinatsu tells Ritsu she should go out on a date with Usa. This causes the latter to suffer a Color Failure, and both Shirosaki and Mayumi are shocked by what the 9-year-old is saying. Ritsu, being completely Oblivious to Love, vehemently denies having any feelings for him and claims he's not interested in her, when in reality, everyone knows he likes her. Made worse when Ritsu accidentally mentions Hayashi, his female friend from middle school, going to the restaurant a lot, prompting Chinatsu to mention Ritsu is jealous of that other girl.
- This is what constantly gets Ebichu in trouble: she doesn't know everything about human sexuality, but she knows far more than is safe for anyone who is otherwise a complete child — as evidenced by the repeated scenes of her bursting in on her mistress and her mistress's boyfriend in the middle of sex, screaming about how they're doing it wrong ("If you're enjoying it so much, why do you keep saying 'No' and 'Stop'?!" or "That's the wrong hole, stupid!").
- When Anzu coaches her Hanamaru Kindergarten classmate Koume in confessing to a boy, it results in Koume screaming "Take me!" As Anzu explains to her shocked teacher, "that's how my Mama confessed to Papa."
- Shino from Seitokai Yakuindomo is a high school student who is physically incapable of going five minutes without making a sex joke. You'd think this was a result of her being a teenager, but no. Flashbacks to when she was in elementary school reveal that she's always been like that.
- Subverted in Runaways with Cute Bruiser Molly, twice:
- In the very first story arc, Karolina drags Molly out of the room just as the Runaways are about to witness their parents making a human sacrifice. Later, when they are discussing it, she solemnly tells them that she knows exactly what they're talking about: S-E-X.
- In the 1907 arc, when child bride Klara explains about her "marital duties," Karolina looks horrified and Molly says, "He makes you do chores?" Karolina then looks vaguely relieved that the idea of sex as marital duty has not yet reached Molly's precocious consciousness. But in the next issue, Molly tells Klara that "It's not even a sin, it's illegal. There's TV shows where they catch guys even..." It's been previously established that Molly's apparent naivete is a pretense she keeps up so that others will keep their guard down around her. In this case, she may even have been trying to break the tension.
- Used brutally when she was kidnapped by a time-traveling Geoffry Wilder trying to avenge his deceased son Alex who manages to call her out on her use of her young age as disarming mechanism and tells her to drop the act. She glares. And then she tells the man "Alex turned out just like you. He was a complete failure." Damn... just damn...
- In Demon Knights, a young girl thanking Exoristos for saving the village from dragons adds "But you dress like a tart."
- The six-year-old protagonist of Squee! objects when his classmate Pepito invites him to dinner:
Father: Your mother and I already made plans to go out, so, like it or not, you're going. I'm hoping they try to keep you.
- Journey into Mystery combines this with an Expospeak Gag from Kid Loki, who has bought a smartphone and discovered the Internet. (He's a reincarnation of, well, Loki, but he has the memories of a child and looks about ten... and being a devious little Child Prodigy godling he's an excellent source of this trope.)
- In All You Need Is Love four-year-old Duck Sherlock Penber shares with his mother the following observation about Mello:
Duck: Look, mommy, his pants are tighter than yours!
- In Scootaloo's first appearance in the Ask Serious Rainbow blog, Serious had been about to insult her stepmother but cut her curse short when Scootaloo came in. Scootaloo, finding out the topic was her stepmother, promptly finished the curse by calling her a 'royal cunt'. Serious just chuckles and asks if Scootaloo was watching George Carlin again.
- Sam's little brother, Mike in Sixteen Candles, about his sister, Ginny, who's getting married:
Mike: She got her period. Should make for an interesting honeymoon, huh?His father: Where are you learning that stuff?Mike: School.His father: Good. Gettin' my money's worth.
- From Airplane!: "I take it black, like my men."
- From the 1998 remake of The Parent Trap:
Annie as Hallie: I don't mean to be jerky when you're trying to be all mushy and everything, but I know what mystery my dad sees in you.Meredith: You do?Annie as Hallie: You're young and beautiful and sexy and, hey, the guy's only human. But if you ask me, marriage is supposed to be based on something more than just sex, right?
- For that matter, both the twins are quite eloquent for 11-year-olds throughout the movie. It's just that this is the only time adult subject matter gets this treatment.
- Much of what Short Round says in Indiana Jones and the Temple of Doom. "Maybe he like... older women."
- From Drop Dead Fred:
Mom: And the prince took the beautiful young girl in his arms and said, "will you marry me?" "Yes", she whispered, "I will be your princess".Young Elizabeth: Did they live happily ever after?Mom: Of course, Elizabeth.Young Elizabeth: How do you know?Mom: Because she was a good little girl. If she had been naughty, the prince would have run away.Young Elizabeth: What a pile of shit!
- From The Wedding Singer:
"Hey, Linda! You're a bitch!""He... he may have Tourette's Syndrome, we're looking into it..."
- From Lethal Weapon: "My Mama says policemen shoot black people!" Mel Gibson was laughing so hard in that scene.
- Eric in Mystery Team Take this scene in a gentleman's club:
Jason: What are you doing here?Eric: My mom works here.(Blank stares)Eric: What? It's better than shaking your shit on the street.
- Inverted in Kick-Ass when Big Daddy is stunned by daughter Mindy's birthday request for a cuddly, fluffy puppy and a Bratz movie star makeover Sasha. She then lets him in on the joke, amending her request to a Benchmade model 42 butterfly knife.
Mindy: I'm just fucking with you, dad.
- Darian to the Big Bad Marcone in The Last Boy Scout: "Eat shit, you fucking redneck!"
- 14 year-old Poppy in Fired Up calls Bianca a "lesbotron". There are ad-libbed alternative readings in the credits, one of which is bleeped out, but could be "you fucking dyke!"
- Leprechaun: "Fuck you Lucky Charms!"
- A defining trait of Wednesday in the The Addams Family movies.
- Iron Man 3: In the middle of a panic attack, Tony's kid sidekick says "if you're a mechanic, why don't you build something?" Tony instantly calms down. What's interesting is that we actually see him testing Tony's PTSD earlier, pushing the limits of acceptable behavior a lot as Tony does.
- A Running Gag in Kindergarten Cop is the little kid who says, "Boys have a penis, and girls have a vagina."
O'Hara: (to Kimble) I see you've covered the basics.
- The scene where the kids talk about what their dads do for work is full of this.
Rina and Tina: Our mom says our dad is a real sex machine.
- The scene where the kids talk about what their dads do for work is full of this.
- In Hocus Pocus, Dani's mocking of her big brother Max's lack of sex life isn't limited to repeatedly saying that he's a virgin:
Dani: (to Alison) Max likes your Yabbos. In fact, he loves them!
- A funny line from Zootopia has an adorable baby hippo, clutching the hand of their mother (who Judy has just given a parking ticket), turning to Judy Hopps and saying in the cheeriest voice imaginable "My mommy says she wishes you were dead."
- In Demolition Man, in an archived story about one of John Spartan's defused hostage situations:
Reporter: How can you justify destroying a seven million dollar mini-mall to rescue a girl whose ransom was only twenty-five thousand dollars?Girl: Fuck you, lady!Spartan: Good answer.
- In American Pie when Kevin and Vicky are about to do it in Stifler's house, his little brother pops out of the closet and says "you guys are gonna fuck, aren't you?" - and Kevin pushes him out of the room all the while he keeps chanting "fuckers", which they find Actually Pretty Funny.
- In Robocop 2, Detroit has deteriorated to the point where gangs of violent and foul-mouthed kids are going on crime sprees. Then there's Hob, who is crueler, smarter and more ambitious.
- Done three times in Jerry Maguire:
Ray: You said "fuck".Jerry: I know. I'm-Ray: I won't tell.
- The first time, it's Played for Drama; when one of his clients (a hockey player) gets his fourth concussion, and Jerry downplays the seriousness of his injury, the hockey player's young son, Jesse, angrily responds, "Fuck you!", and flips the bird at him. This leads to Jerry's Heel Realization.
- Second, when Jerry is visiting Dorothy, he's talking with Ray, and Ray keeps pestering him to go to the zoo, at which point, Jerry, who's drunk, says, "The fucking zoo's closed," and immediately regrets it.
Marcee: Why don't you be the first man in your family not to use that word, and then we'll let you live.
- Later, when Rod's family is watching him on TV, and Rod scores a touchdown, Rod's son Tyson yells out, "That's my mo-fo!", which does not please his family.
- A country pastor is walking in the fields when he runs into a tiny girl leading an enormous bull on a rope.

"Oh no, Reverend, his dick is much too small!"
- Sefalet's left-hand mouth says things no child should say in Dirge for Prester John. And she has no control over it.
- Subverted in one book of the Myth Adventures when Skeeve ends up taking care of a precocious little girl because he won her in a card game. She says Darndest Things at horrible times and adult characters have their hands full explaining things to her. Turns out, she's an adult of a species that always looks like children and she's a character assassin who was saying those things deliberately to ruin Skeeve's business.
- In The Nightingale (Kristin Hannah), Sophie rebuffs Vianne's attempt to console her, by claiming that no, she won't see Sarah in heaven, because she was Jewish. Sophie makes it clear that she sees this as a patronizing comment from Vianne and does not appreciate it. Vianne is too shocked by this response to reply.
- Wax and Wayne has Marasi — a female rookie cop — questioning a little boy on the street about a suspect...
Marasi: We're looking for a man.Kid (leering): If you need a man, I'm right here.Marasi: Oh please. You're... what, nine?
- Older Than Radio example with The Emperor's New Clothes: "But he has no clothes on!"
- In the Monument 14 Trilogy, grade-schooler Max has all kinds of hilariously candid stories about his family. Dean suspects that he's lived a very interesting life, to put it mildly.
- My So-Called Life: When fifteen-year-old Angela begins hanging out with an effeminate Puerto Rican boy, her mother Patti objects. Danielle, who delivers the final line here, is Angela's nine-year-old sister:
Patti: I find Rickie a little confusing.Angela: Okay, so maybe he's bi. Who cares? His cousin can still drive.Patti: What? He is what? Do you hear these terms she's throwing around? Bi?Danielle: It means bisexual.
- In the Leave It to Beaver TV series, Wally tries to upbraid his little brother for falling for a panhandler's story. When he calmly states that he knew perfectly well the panhandler was making it up, Eddie demands to know why Beaver gave him money. "Because nobody ever told me a story like that before."
Beaver: Have you ever kissed any other married woman besides Mom?Ward: Why Beaver! Why would you ask a question like that?Beaver: I'm just wondering.Ward: Well, actually son, no.Beaver: I guess you were scared to, huh?Ward: Yeah, that's as good a way as any to sum it up I guess.Beaver: I guess a guy could into a lot of trouble doing that, huh?Ward: (looking off into the distance, mumbling) He sure could... uh, buh Beaver, I've got to finish this plug son, so you run off and play.
- In another episode Beaver asks Ward if he's a married man. Ward assures Beaver that he is. Beaver asks if June is a married woman. Ward assures Beaver that she is.
- Done repeatedly on Two and a Half Men. Jake would hear or see something at his uncle Charlie's house that his father, Alan, didn't want him to be exposed to. Alan would then launch into some bizarre explanation in an attempt to protect Jake's "innocence". We then learn that Charlie and Jake were just messing with Alan and that Jake already knew what was going on.
- Intentionally invoked by The Man Show, with a kid they hired as "The Man Show Boy", who would go around town saying things to people they wouldn't expect a kid to know.
- In The Fresh Prince of Bel-Air episode "Be My Baby Tonight", 13-year-old Ashley asks Will to tell her everything he knows about sex. He is appalled as she goes on to say that she knows all about eggs, sperm and fallopian tubes. He says, "Am I going to have to wash your mouth out with soap, young lady?"
- In The New Normal, Shania calls Jane a bigot, and unfriends her.
- In a season 3 episode of Good Luck Charlie, Charlie managed to scare off all of Amy's baby shower guests after revealing her mother's true feelings towards the guests.
- Mad Men:
- While visiting her dad's office, Sally Draper, about seven, tells Joan Holloway "You have big ones. My mommy has big ones, and when I grow up I'm going to have big ones too." (She later drains a glass of his booze too.)
- In the Season 4 episode "The Chrysanthemum and the Sword", Sally asks her babysitter, Don's neighbor, if she and Don are "doing it", and says she knows that the man pees inside the women.
- An occasional source of humor on The Sopranos: the adults swear constantly, but when a child (especially their own) does the same they're appalled.
- In the Veronica Mars episode "Green-Eyed Monster", Wallace mentions to his mother he's going to be giving Jackie a hand with her trigonometry. He's not being very subtle with his entendres, but it is still a shock to him and his mother when his little brother Darrell pipes up, "Are you hitting that?"
- Played with amusingly My Wife and Kids, Michael and Jay attend Kady's school play. The children at the end shout to the audience "You put the peanut in the peanut hole!", a line which none of the parents seem to get. It's only in the evening when Michael (in bed with Jay, no less) figures it out:
Michael: "You put the peanut in the peanut hole", I get it!Jay: I still don't get it.Michael:You will...(moves in closer to Jay and turns the light off)
- Jimmy Kimmel thought it would be funny for parents to record themselves telling their young kids that they ate all the Halloween candy. Here's the result.
- On Everybody Hates Chris, the babysitter they have in one episode is a teenage mom. Tonya tells the babysitter's mother "My mom told me she would kick me out if I had a baby 'cause she ain't raisin' no babies. Why didn't you kick her out?"
- The 4400: In "Tiny Machines", Maia inadvertently reveals to the Marked in control of Tom Baldwin that NTAC are on to him when she tells him that Meghan has been coming over at night to talk to Diana all week.
- EGM had two articles where kids of the new millennium were asked to play games from before their time and interviewed on their opinions. The results were precious.
EGM: Who's that chick Mario is rescuing up there (in Donkey Kong)?
Brian: It's Princess Peach.
Kirk: It's a hooker.
Niko: She looks cut in half.
Tim: Oh wow — she's one of those pole dancers.
- As a side note, that's Pauline, not Peach.
- The comic strip Calvin and Hobbes did this frequently, as Calvin knew just enough about the adult world to get into trouble. In one strip, Calvin lectures his father that everybody must do their part for the economy; in other words, his allowance should be raised so there is more money in circulation. His father says, "I've got to stop leaving the Wall Street Journal lying around." Later strips used Calvin's incredibly-non-six-year-old worldview to make political or societal statements. Even more incredibly, he did it without ever becoming preachy or heavy-handed.
Calvin: Why would it be worth four dollars a minute to talk on the telephone to goofy ladies who wear their underwear on TV commercials?
Mom: When were you watching that?!
Calvin: Um... it was on...uh...during my morning cartoons.Calvin: Do you have any kids, Uncle Max?
Max: Me? Nope, I'm not even married.
Calvin: Oh. ...What difference does that make?
Max: Kid watches a lot of TV, does he?Calvin: Boy, what a day! I went to school, played outside, and did my homework. I'm exhausted. You know what time it is now?
Dad: Uh, 7:35.
Calvin: It's Miller Time.Calvin: Why do you live in this house with Mom instead of an apartment with several scantily clad female roommates?Rosalyn: It's my job to watch you, and that's what I'm going to do, even if I have to strap you to a chair. Got it?
Calvin (saluting with one hand and clicking his heels): Jawohl, mein Fuhrer!
Rosalyn (grabbing Calvin by the shirt): Care to repeat that little comment?
Calvin: I said I'm not going anywhere. Leggo.
- For a seven-year-old, Mafalda certainly knows a lot about politics. So do her friends, to a degree.
- This trope is a standard one for Peanuts with the characters frequently displaying a vocabulary and grasp of concepts you'd never expect kids to have:
Linus: [Doing the classic finger gestures with this rhyme for Sally]: "Here's the church...here's the steeple...open the door...and see all the people!"Sally: "It looks like a rather small congregation."
- This is presumably the appeal of the boy's companies (such as the Children of Paul's) who operated during the sixteenth century. The comedies of John Lyly are a good example.
- Persona 3 has a fun example. New Year's day has the guys in the team admiring the girls in their kimonos. The resident cute little boy Ken asks if the girls are cold. When questioned why it's because Junpei says that they wear nothing underneath. Cue Yukari stomping on Junpei's foot and asking if he told Ken anything else. (This may be better in Portable when it's possible to have a romantic relationship with Ken)
- Solatorobo contains a mild case. While Elh manages to confuse Red and Chocolate about being female, one of the orphans immediately realizes she's a girl and asks her why she dresses like a boy. Red replies that it makes it easier to play, volunteering a flustered Elh for babysitting duty. Only question is, how exactly did the kid know that...?
- The first Dark Brotherhood quest in The Elder Scrolls V: Skyrim has you killing the vicious woman who runs the orphanage. The children cheer you after the deed, but one girl very calmly acknowledges that killing one person can solve a lot of people's problems and that she is "wondering at the possibilities."
- Fallout 3: Most children—unsurprisingly, given that the series is known for its Black Humor. Little Lamplight, in particular, has some kids using all but the most taboo swear words in every sentence.
- Grand Theft Auto: Liberty City Stories: A seven-year-old calls in to Chatterbox and has a brief conversation with Lazlow. Then...
Caller: Lazlow, do you know what "Fuck me harder" means?
- Kinder: The children's ages range from 2nd grade up to 6th grade, and they are all aware what is going on with adults. Yuuichi speaks rather nonchalantly about his father's repeated cheating on his mother, and Shunsuke admits he realized at a young age that his mother was his father's mistress, and not his lawful wife, as he initially thought. And Sayaka herself runs on this trope. At one point, Sayaka and Ryou are playing 'adultery between a boss and his secretary', where Sayaka is blackmailing Ryou over incriminating pictures she took.
- In The Last of Us, Ellie surprises Joel in that she is a wise-talking, swearing, clever girl (who is also handy with a gun or two and not afraid to complete dangerous tasks). There's also her reaction to a gay porn magazine she finds:
Ellie: Light on the reading, but it has some interesting photos.Joel: Now, Ellie, that ain't for kids...Ellie: Whoa... how- how the hell would he even walk around with that thing?Joel: Get rid of that! Just-Ellie: Hold your horses, I wanna see what all the fuss is about. Oh... why are these all stuck together?Joel: Ummm...Ellie: I'm just fuckin' with you. *throws magazine out the window*
- The Cyantian Chronicles: Tae, during a conversation with Kea. Tae and Kea together, at points. Kibi, who is smarter than many adults. Collin and Quinn, during Akaelae.
- Ghastly's Ghastly Comic: Tentacoo wape!
- Christine, Sonichu and Rosechu's daughter from Sonichu does this in the Christmas special whilst dressed as the Virgin Mary for a school play. "I am the Virgin Mary. That's my story, and I'm sticking to it." (Incidentally, she's a little kid. Although most people who know about the author seem to think he has no idea what the line actually means.)
- Jay Naylor's Better Days often invokes this to deliver a moral so objectivist it would make Steve Ditko puke himself.
- Jason has a very awkward time playing Santa.
"My mommy says you're a pagan representation designed to steal glory from Christ and I should tell you you're gonna burn in Hell forever. I want a Barbie."
- Kestrel has just as bad a time as the Easter Bunny.
My mom says you can't be too careful at events like this. They let just anyone show up and she says if I'm not careful, I'll catch an airbourne disease, like atheist or negro.
- Jason has a very awkward time playing Santa.
- This xkcd strip, in which a child finds "Daddy's Sports Illustrated Swimsuit Issue" - and has seen so many inappropriate things on the internet that they're shocked that the girls have clothes on. "Parents, talk to your kids about popup blockers."
- Kids in Scary Go Round (and other Bobbinsverse comics) are prone to this sort of behavior, as here.
Humphrey: Daddy said I should hide my piggy bank while you're here. But he said it wouldn't be for long.
- Whateley Universe: In combination with You Need to Get Laid in Raises the Sun (Part 1):
Youre stiff like that guy Daddy talked about at the Palace. The young six-year-old piped up. Before anyone could say anything, she continued. You need to ... oh, yes, go to a strip club and relax, as Daddy said about that guy. Pausing once again, with James repressing a snicker, and a slight glare from Kiko to her husband as he cringed slightly, she then burbled on. Though whats a strip club?
From the mouth of babes, eh?
- '80s All Over spoofs this in the November 1983 episode with an Imagine Spot of sorts in which an "11-year-old" Scott Weinberg profanely complains about the perceived Bait-and-Switch of The Smurfs and the Magic Flutenote . Co-host Drew McWeeny jokes that Scott's dad must have been shocked to hear that!
- Early South Park was based almost entirely around this trope. For extra funny/cute/disturbing points, any kids younger than the core cast's 8-10 bracket are almost always voiced by actual kids in the same age range (meaning Ike is always voiced by a real toddler and the Kindergartners are voiced by 4-5-year-olds).
- Commentary for the 10th season episode Smug Alert has Trey Parker and Matt Stone saying they did the episode primarily so that they could have the child voicing Ike say "Tripping Balls."
- The movie focused heavily on this too, but later episodes it seems the adults have given up (in the case of some, like Counselor Mackey and Randy Marsh, they have their own issues to deal with).
- Yakko, Wakko, and Dot. Yakko's physically about 14, Wakko's physically 10, and Dot's physically 8. And yet, some of the things they say are a bit...
"Let me know when those costumes get heavy, ladies!"
- This gem from The Adventures of Jimmy Neutron: Boy Genius, which deconstructs the Fridge Logic of a 10-year-old genius with an extensive knowledge of human biology when Jimmy tells his parents that he wants a baby brother:
Hugh: (Spit Take) Baby making is very... complicated, believe me.Jimmy: Dad, Dad, it's not complicated. Really, really, it's —Hugh: You don't know —Jimmy: It's basically conception, right?Hugh: (Sticks fingers in ears and hums "la la la la")Jimmy: ...then a nine-month gestation period...Hugh: La la la la...Jimmy: ... and then you have...Judy: Sweetie, a new baby just isn't in the cards right now.Hugh: That's enough! OK! Ha-ha, I want pie! Anyone else want pie? I want pie!
- Avatar: The Last Airbender: Meng, a pre-teen girl, calls Katara a floozy under her breath when she learns Aang (whom Meng had a crush on) prefers Katara.
- From The Legend of Korra, seven-year-old Ikki sees nothing wrong with letting Asami know that her friend Korra is in love with her boyfriend.
- On one episode of King of the Hill, Hank jokes with Bobby about girls having cooties, only for him to ask what cooties are. Hank explains that it's the disease that you get from girls, only for Bobby to reply, "Oh, you mean like chlamydia?"
- Quoted verbatim in the couch gag of The Simpsons episode "The Cad and the Hat" where Homer enters a parody of South Park with the four boys spouting constant bleeped profanity.
- On The Critic, Alice Tompkins' daughter, Penny, got a fair amount of mileage off of this.
Penny: What's the matter, Mama?Alice: Oh, sweetie. You wouldn't understand.Penny: Are you afraid the man you love has left you for another?Alice: What?! Where'd you learn to talk like that?!Penny: It's "Men Are Scum" week on Ricki Lake.
- Much of Louise and Gene's humor on Bob's Burgers comes from this: Gene is rather innocent for his age and oftentimes doesn't recognize why something he's said is inappropriate. Louise, on the other hand, isn't innocent enough for her age, and deliberately says some of the things she says because she enjoys being The Gadfly.
Gene: Channel 9 News! They'll finger anything with a pulse!Bob: I'm pretty sure it's "Their finger's always on the pulse."Gene: No.Louise: My mom and dad are downstairs grinding the meat right now.Hugo: Uh-huh-
- Tina lies somewhere in the middle; being 13, she is old enough to have some academic understanding of such topics, but she lacks the social grace needed to avoid talking about them at inappropriate times, such as when she started talking about her erotic zombie night terrors during breakfast. To her father. Bob ends up begging her to stop talking.
- Transformers Animated has an epic moment from 8-year-old Sari Sumdac, who completely shatters Optimus Prime's innocence by telling him about the birds and the bees.◊
- 1960s-vintage Talk Show host Art Linkletter had a regular segment on his program House Party called "Kids Say The Darnedest Things" — later spun off into a show itself — in which he interviewed children to solicit these kinds of observations for their comedic value. (Being the 1960s, they were — generally — a bit milder than today's version.)
- Bill Cosby picked up this ball from 1998-2000, with the show Kids Say the Darndest Things, which has yielded at least one compilation book.
- The infamous Balloon Boy hoax was busted when during a news interview, the boy in question told the truth that "You guys said that, um, we did this for the show." when asked why he didn't come down from the garage when called.
- Not Always Right has a lot of these.
Me: Can I help you?Child: I dont get it.Me: What?Child: Are you old or just simple?Me: Excuse me?Child: Cause my mom said everyone who works at [supermarket] is either old or simple.(The mother comes running behind him, picks him up, and runs off.)
- Don't Butt in Line, if You Can't Pay the Fine. When politeness doesn't get a five-year-old anywhere, adult language does.
- The Daily Mail, a conservative British Newspaper, has a similar section among its letters page.
- Zigzagged on Supernanny - sometimes, the children who swear are simply repeating the words they heard their parents yelling; other times, they know exactly what they're saying and what the words mean.
- Bill Engvall says this about when he had to have The Talk with his son:
So I sat him down and said, "Son, I know you already know a lot of things, so why don't you do this: why don't you tell me what you know, and I'll just fill in the blank spots." About 30 minutes later, I'm sitting there with a pen and a pad of paper, going, "You can DO that?!?"

- Dara O'Briain mentions this happening in a story he told on the DVD of 'Craic Dealer' at about 47:22.
- Blake Lively says that when her daughter James first learned to talk, she had an unfortunate habit of turning words that start with 's' into 'sh'. So when she asks for someone to come sit with her...
"I have Amy Schumer as a daughter."
- Mara Wilson describes her mother telling her about sex when she was five years old. But she had to film Mrs. Doubtfire the next day and apparently ran around the set shouting "I know what sex is!" and variations of that. The crew and Robin Williams found it Actually Pretty Funny. Mara's mother did not.
- Eavesdrop on any group of children playing together and you're bound to hear something kind of messed up eventually. Kids swear and play games where they "kill" each other pretty much daily.
- Samuel L. Jackson has said that his typical Cluster F-Bomb rubbed off on his daughter from a very young age, and she would thoroughly shock other parents by dropping f-bombs at parties.
- During the filming of Logan, there was a scene where Logan (Hugh Jackman) had to shout at Laura (Dafne Keen) "SHUT THE FUCK UP!", which went on for 40 minutes, and after that he went to María, Dafne's mother, to apologize for that. María cheerfully replied that Dafne had just called him a cunt in Spanish.
