- In the Ace Attorney manga, Turnabout Showtime features an example in which it is not revealed that the person has made a mistake until very late in the trial. Raymond Spume yells at Julie Henson for "biting her nails during the show just like (she is) now!" when pulling the murdered Flip out of his costume. It turns out that Sparklestar's (the mascot Raymond plays) back was turned to Julie while she was biting her nails, meaning that Raymond could not have seen her doing it unless he was wearing his costume backwards, which would enable him to unzip it and stab Flip, who was also wearing it the same way so that he could perform a backflip the same way he did a front flip.

- A humorous example in Dragon Ball Z: Battle of Gods, Goku is talking about how awesome it was for Vegeta to stand up for Bulma after she was slapped by Beerus, getting that massive power-up from it. In his talking, he haphazardly mentions that they should get Bulma slapped again to get that boost again, leading to Bulma slapping Goku... before Piccolo realizes something: How did Goku know about the incident? As it turns out, Goku had been watching from a distance the whole time.

- In Gotham Central, as a result of having been working long hours and being generally tired and depressed, Renee Montoya accidentally lets slip to Maggie Sawyer, captain of the Major Crimes Unit, that Romy Chandler had her weapon taken by Batman after she tried to shoot him.
Marcus Driver: What, you figure I should just shoot over to this Tailor's place, get myself a Batman costume? Dress up and try to make Dunning wet himself?
Josie Mac: Yeah, on second thought it's probably not such a good idea, Romy might try to bust a cap in your ass.
Renee Montoya: Yeah, well, he'd have to give her weapon back, first.
Maggie Sawyer: What was that?
Renee Montoya: Oh, Hell.
- During the Go Down Swinging arc of Spider-Man, J. Jonah Jameson is being held captive by Green Goblin, whos long forgotten Spideys true identity after regaining his sanity and purging his split personality.

Jameson is horrified when he realizes just how badly he messed up.
- In Calvin and Hobbes, Susie narrowly avoids getting hit by a snowball, and promptly goes to confront Calvin, who denies doing it, and that she could never prove that he did.

- Once More with Feeling: When Shinji was interrogated by SEELE, he accidentally slipped how much Misato means to him, and he realized belatedly that he gave SEELE a leverage to manipulate him. Worse still, his body language gave away that he knew who Khiel -someone who he supposedly had never met before- was, and Khiel noticed.
- Chapter 5 of The Second Try gives an interesting version. After the battle with the 14th Angel, Misato finds (a little too late) an "anonymous" note from Shinji, meant to warn her about EVA-03 being possessed by the 13th angel... That he had written out by hand. She, of course, recognizes his handwriting, and a quick peek at his schoolwork confirms that he wrote it. She then remembers his and Asuka's odd behavior, and realizes that Asuka may know something about the letter. When she confronts Asuka, who is extremely distraught at the time (for very good reasons), Asuka breaks down and lets the facade drop.
- Quicken: When Danny talks about how happy his daughter Taylor used to be, Emma gets worried, because he's unintentionally revealing that her best friend hasn't been happy for a long, long time.
He reminisced some more as I listened, but I wasnt paying attention to what he said so much so as what he didnt say. He kept talking about how happy Taylor had been before with the two of us, back in the past, not how she was now. Unease wound itself inside me, as I thought about the implications of what he wasnt saying, what he had left unstated.
- In the Miraculous Ladybug fic Fermeture, Marinette tries to arrange a reunion with her former partner Chat Noir, who she hasn't seen since they both lost their powers five years ago, as they never learned each other's secret identities. She uses the Ladyblog to ask him to meet her at their "favourite spot", assuming he'll recognise it as the Eiffel Tower on Christmas Eve before midnight, and ends up waiting there with her former crush Adrien, who's also waiting for someone - Marinette assumes this to be Chloe, who she overheard talking with Adrien on his cell phone a couple of weeks earlier. Midnight passes, and Marinette believes she's been stood up (or that Chat didn't see the invitation to begin with) and prepares to leave, but when she mentions Chloe and the phone call, Adrien explains that the call was just Chloe telling him about the blog post in which Ladybug asked Chat Noir to meet there tonight.
Marinette: Wait. You said she told you they were meeting here tonight. How did you know that? The note never said where they were meeting!Adrien: I, uh Did I say that? I mean, it was just a guess, really. They, uh, used to spend a lot of time here, soMarinette: (believes his answer, and starts to tear up at another seemingly crushed hope) Was it really? Was it really just a guess?Adrien: Wait. You asked how I knew. How I knew, not why I thought so. Is this really where they were going to meet? Why are you so sure? How are you so sure?Marinette: Because Im the one who wrote the damn thing in the first place!
- In What's Done in the Dark..., when Brother Veritas is attempting to console his student Princess Cadance after the latter sees her husband Shining Armor and aunt Princess Luna kissing, he namedrops Luna as Shining Armor's mistress even though Cadance hadn't named her, causing Cadance to realize that he had known about the affair and ruining his attempt to calm her, in fact triggering her Superpowered Evil Side.
- In Chapter 9 of Intercom, Riley is casually talking to her friend Ann about the latter's choice of hair dye, until she accidentally kets it slip, "Disgust likes it too, it matches her scarf."

- When Adrien and Marinette's Valentine's Day date is interrupted by an akuma attack, both Ladybug and Chat Noir give each other a few too many clues, leading each to suspect the other by the end of the night.

She also tells him to wipe the lipstick off before he sees his girlfriend again, echoing advice Marinette gave Adrien that day.
- While the four are usually pretty good about not revealing information to outsiders in The Keys Stand Alone: The Soft World, the disguised George and Ringo get so comfortable with the Six Step Combo that Ringo accidentally reveals that they're much older than they look, and George accidentally reveals that his guitar is not the one-of-a-kind prototype that he claimed it was. Luckily, the Six Steppers already knew they were frauds and didn't care.
- Works in SG-1's favour in Remnant; Zipacna was trying to pose as Daniel Jackson and convince SG-1 that 'he' was willing to be Zipacna's host to get more information about Anubis, which Jack, Sam and Teal'c might have believed... but then, while trying to convince them, he refers to the destruction of Abydos and "the family of my Amaunet", which instantly ruins the illusion.
- Granted, Daniel may have exerted just enough control at that moment to make Zipacna slip up, but the Goa'uld still might have won SG-1 over if he'd just stopped talking a moment earlier.
- Played for Laughs in Teen Titans: Together for Tomorrow: Lois discovers Conner is Superboy after seeing him fly in civvies, and works out Clark is Superman. When she goes to confront Superman, Conner refers to him as "Dad" while hastily explaining why the secret identity leak isn't his fault.

Victor Quartermaine: Oh, no. You commissioned me to rid you of [Anti-]Pesto, and that's just what I intend to do... Oop!

Victor Quartermaine: Argh... Oh, alright! So what if it is that blithering idiot? No one will ever believe you!
- In The Lion King, Scar "accidentally" lets slip to Simba that the forbidden area beyond the Pride Lands has an Elephant Graveyard (which, of course, piques Simba's interest) and laments the fact that he said too much - but not really, as it's part of his Batman Gambit to get Simba killed.

- In Kiss the Girls, this is intentionally done on part of the Serial Killer. Kate first starts to suspect that she's Alone with the Psycho when he knows where her colander is without being told. He then proceeds to discuss in detail what kind of information a bad guy could get by going through her trash, before finally dropping pretense altogether to tell her exactly what he discovered when he went through her trash.
- It ends up being a crucial plot point in L.A. Confidential - Capt. Dudley Smith reveals that he's the one who killed Jack Vincennes by asking Ed Exley to investigate a name Vincennes dropped as his last words - "Rollo Tomasi". Except that "Rollo Tomasi" happens to be a name made up by Exley for his father's unknown murderer; he'd told the story to Vincennes on the previous day. Vincennes does the same thing in his death scene when he tells Smith that he hasnt yet told Exley what hes found out, whereupon Smith deems it safe to kill Vincennes.
- Moulin Rouge! first has a heavily sarcastic version:
Nini: (to the Duke) I don't like this ending. Why on earth would she go with the penniless writer? Oops! I mean sitar player.
- The second one comes as a response to this:
The Duke: Why shouldn't the courtesan marry the maharajah?
Christian: Because she doesn't love you! ...him. She—she doesn't love him.
- The first example is a deliberate leak, while the second is accidental.
- The second one comes as a response to this:
- Several instances in Mystery Team:
"I wish they'd all disappear like The Lost Colony of Roanoke. But they'd probably go, 'What's Roanoke?' And I'd go, 'Shut up, Caleb.'"
"Following your dreams is never stupid, unless you dream about water and then you pee the bed last Thursday."

- In Reindeer Games, after the wild robbery, Rudy is about to be killed by Ashley and Gabriel. Rudy fires off on Ashley on how Nick (who he'd been impersonating) had truly loved her before dying in prison.

After a pause, Ashley pulls a gun to shoot Gabriel. Out comes a very much alive Nick to reveal he'd faked his death and he and Ashley were together on this the whole time.
- Star Trek II: The Wrath of Khan: Chekov unintentionally informs Khan that the Reliant wasn't looking for him, and they had in fact assumed they were on a different planet. It takes several minutes for Khan to realize this, but when he does, things rapidly go downhill for Chekov and his captain.
- Star Wars: Episode VI Return of the Jedi: Palpatine, Magnificent Bastard, mastermind of two sides of a galactic war, commander of The Empire
and can't resist gloating like a third-rate comic book villain when Luke is about to finish off Vader, which causes Luke to realize just how close to The Dark Side he's going and stop himself.
- Palpatine does this AGAIN in The Rise of Skywalker. He explains to Rey that if she kills him, he'll possess her and rule as Emperor again in her body. Rey was there to kill him anyway, so had he just said nothing his plan would've succeeded. Instead, Rey ends up reflecting his Force Lightning back at him, which means he technically killed himself and his plan fails.
- In Two Days In The Valley, Teri Hatcher has hired killers to murder her husband. One of the police detectives notices that she says, "They killed my husband," implying that there were multiple murderers when the police hadn't established this fact yet.

- In Douglas Hulick's first novel, Among Thieves, the main character Drothe has been tracking down a powerful book that there are rumors about, but which nobody has much information on, for his boss, Kells. Eventually he finds it, but when Kells asks what he's found, he tells his boss that he's not going to give him any information about "that damned journal" until Kells tells him what's going on. Kells realizes he's found the book, as everyone else has just been calling it "the book": nobody else knew it was a journal specifically.
- In the Commonwealth Saga short story "The Demon Trap", Paula Myo is investigating a terrorist who has not only had his memories wiped, but a completely different set of memories implanted, but still proves his involvement because of a DNA match at the scene, and a mismatch where the person whose memories he has was sick. The head of the political party with the same aims as the terrorist group denies any involvement, but decries punishing a man for a crime his current personality didn't commit. In the process he describes the stewardess in sufficient detail to convince Myo that he provided the fake memories. It eventually transpires the entire movement consists of genetically-altered clones with a Hive Mind.
- In The Diamond Age, Inspector Chang returns Hackworth's top hat, saying that he got it from a suspect.

- Discworld: Moist von Lipwig fell into this trope in Making Money when he was attempting to talk his way around Captain Carrot's Exasperated Perp tactic by telling Carrot that he knows what he's trying to do to him. Carrot then promptly thanked him... for informing him that he's quite familiar with that tactic and thus implying his rather shady criminal past. Whoops!
- In almost every Encyclopedia Brown story involving Bugs Meanie, this sort of thing gave Bugs away; he usually had to defend a lie with another lie that made what he said earlier contradictory.
- In Isaac Asimov's story Galley Slave a professor sues US Robotics, accusing a proofreading robot of altering his work. When the robot testifies, the professor blurts out "Damn you, you were instructed to keep your mouth shut about..." Oops. He had made the changes himself, then brought the case to make a point against automation. The real twist is that the robot wasn't going to tell the truth anyway, since the First Law (manifested as a desire to protect the professor's reputation) trumped the fact that it would be scrapped if it didn't speak out (Third Law), as well as the order to be quiet (Second Law). The only reason for US Robotics' lawyer to call the robot to testify was in order to trick the professor, who distrusted robots and was deliberately ignorant of how they worked, into making that slip, by providing the robot with a higher-level First Law trigger that trumped the initial one.
- Harry Potter
- Poor Hagrid is prone to this, especially when he's distraught or talking to the Power Trio. He lets slip the means to calm Fluffy the Terrible, the name of a warlock who helps immensely with a search he doesn't want them to succeed in, and several other pieces of relevant information over the course of the books. Often lampshaded by Hagrid himself immediately after: 'I shouldn't have said that'.
- It's also how Harry discovers the imposter in Harry Potter and the Goblet of Fire.
- In Shadow of the Conqueror, Daylen frequently says and does things that don't make sense for someone so young or with his limited life experiences, which he constantly has to make up explanations to cover. These mistakes eventually lead to Ahrek figuring out that he's actually Dayless.

She also has to work hard to avoid sounding as well-educated and astute as she really is, but Dove still notices every time Aly slips up.
- 30 Rock:
Jack: Lemon, we have a problem.
Liz: I have this whole Tracy-Josh thing under control!
Jack: What are you talking about?

She does a rant on how her brother Jordan smoked weed and got into trouble and the parents just acted like it was fine and never punished him. At which point, their reactions make Olivia realize the reason Jordan wasn't punished was because their mother never knew about this in the first place.
- From Angel 5.15 "Shells":
Knox: I don't just care about Fred - I practically worship it.
Gunn: You said "it".
Gunn: Not "her". You said "I worship it".
Knox: [smirking] Oops.
- In this context, "it" refers to the goddess Illyria, about to be reborn via the sacrifice of our beloved Fred. Fred is the "her". In this case, Knox believes that only Fred was worthy to be Illyria's host.
- And from 5.22 "Not Fade Away", Hamilton lets a little too much slip during his Badass Boast while beating up Angel:
Hamilton: Let me say this as clearly as I can: you cannot beat me. I am a part of themthe Wolf, Ram, and Hart. Their strength flows through my veins. My blood is filled with their ancient power.
Angel: Can you pick out the one word there you probably shouldn't have said?
Angel vamps out and drinks Hamilton's blood, granting himself the same power Hamilton was boasting about.

- Buffy the Vampire Slayer: In the final episodes of season 4, Spike, using "the Yoko Factor," has successfully turned Buffy and the Scoobies against one another by exploiting the existing tensions within the group. In the next episode, Spike, having realized that he gave the information necessary for Adam's plan to Willow, and now Willow won't be speaking to Buffy, meets up with Buffy and tells her that just because they had a falling out doesn't mean they can't focus on decoding the info; as Spike wasn't around to see their falling out, Buffy puts two and two together and realizes that Spike set them up.
- In Castle's pilot, the brother of one of the victims, when asked about an alibi, provides alibis for the three murders. Castle feels downhearted, but Beckett points out that, while it is possible he'd know his alibi for his sister's death, the fact that he was prepared for all three murders (without even asking when the other victims were killed) is quite suspicious. He did it.
- On the second episode of Charmed (2018), the girls believe they have gotten the spirit of their mother to help them. Whitelighter Harry warns them this is an Imposter Demon using knowledge of the girls for its own gain. At first, Mel refuses to believe that, insisting this has to be their mother. The demon claims Mel can trust her as they were always closer than with Maggie. Mel stabs her, noting that "our mother never played favorites."
- Whenever Stephen Colbert gets carried away in a rant and forgets he's not supposed to be talking about himself. On how High School Musical could be made more realistic:
Stephen: If [the main character] went anywhere near the theater department, the football team wouldn't join him in a peppy dance number! They'd string him up on a goalpost by the tights of his home-made Romeo costume, and chuck stale Tater Tots at his head until I wet my pants! - his pants, his pants!
- Another example, after 'Papa Bear' Bill O'Reilly appeared on his show, Colbert showed a clip of The O'Reilly Factor the next day where Bill says "Colbert blew me right away." Cue rant from Colbert how this was supposed to remain secret, how heartless O'Reilly was and it wasn't right away, they had dinner first. He goes onto his next segment where he uses the same phrase and realizes what Bill meant.
Stephen: Oh, my. I have misjudged him. And perhaps said too much.
- This was common when he was on The Daily Show, too. Several installments of "Even Stevphen" ended with him and Steve Carell having turned the topical "debate" of the day into a thinly-veiled or not-at-all-veiled discussion of their personal lives.
Steve: [on why Elian Gonzalez shouldn't go back to Cuba] Well, isn't it obvious, Stephen? A delicate boy like that shouldn't be with his father. I mean, think about it. If he goes there and lives with his father, you know what he's gonna hear. "No, Elian, Daddy can't go camping this summer, things are just too crazy at work," or, "No son of mine is going to take pottery class," or, "Why aren't you tougher? You get beat up in school, you fight back! You don't go crying to the principal like a wussy little girl! Suck it up! Suck it up! Suck it up, Steve!"
- Another example, after 'Papa Bear' Bill O'Reilly appeared on his show, Colbert showed a clip of The O'Reilly Factor the next day where Bill says "Colbert blew me right away." Cue rant from Colbert how this was supposed to remain secret, how heartless O'Reilly was and it wasn't right away, they had dinner first. He goes onto his next segment where he uses the same phrase and realizes what Bill meant.
- On Community, Troy has a tendency to do this, adding "Whoops" without changing the tone.
Troy: How do you know it was our design? We submitted in anonymously. Whoops.
- Dark Matter: One of the things which tips off Six to the fact that he's in a simulation is Three knowing his wife's name, which he never told him.
- Death in Paradise: In "Murder on the Day of the Dead", Finn Anderson apparently receives a voicemail from his wife in which she is being attacked by someone with a knife. He runs to find DI Mooney to inform him that he believes his wife has just been murdered, but Mooney finds it curious that he would say she was murdered, rather than attacked, without knowing for sure that she was dead and correctly guesses that Anderson already knew his wife was dead, and was involved in her murder.
- Doctor Who:
- In "The Time Meddler", the Doctor has disappeared in 1066, and in order to find him Steven interrogates a suspicious monk who swears up and down he hasn't seen him. Steven asks the Monk kindly to keep an eye out for him and asks "Do you remember the description I gave you?" to which the Monk responds by listing off the Doctor's physical traits long white hair, a walking stick, and strange-looking clothes. Steven leaves to tell Vicki that he's confirmed the Monk has seen him, as he never gave him a physical description.
- In incomplete serial "Shada", Chronotis blurts out his real identity (the extremely powerful and dangerous Time Lord outlaw Salyavin, who is being sought by the villain as a vital component to his plan) in a sudden slip of the tongue at the exact point when the villain thinks Salyavin is gone forever, is patching things up with the Doctor and is just about to give up on his plan and go home basically, the worst possible time. Since this is a case of the character having his brains splattered across the wall by the Idiot Ball (as he'd kept his identity a secret for over 700 years until then), the novelisation alters this to have the companion figure it out and announce it to the Doctor (and the villain, who he is comforting after a Villainous Breakdown), thinking Salyavin is a danger to the Doctor and not realising that Salyavin being alive is crucial to the villain's plan, and plays it for excruciating Dramatic Irony.
- "The Unicorn and the Wasp": The Doctor and Agatha Christie are trying to solve a murder mystery, and accusing everyone in the room about certain facts that could point towards them being the killer. Christie points to one man who is wheelchair bound, who in turn cracks under the pressure and admits that he can walk and was only faking being paralyzed, afraid that that was the only thing holding his marriage together. Christie then admits she wasn't actually going to confront him about anything.
- "Midnight": The entity, after managing to steal the Doctor's voice and paralyze him, ends up being so smug about this that it flaunts the fact too much. Even if almost everyone else was too paranoid and thick to notice "Sky's" sudden smugness, the hostess figures it out when the entity uses some of the Doctor's catchphrases, which she'd noticed him saying before the trouble started...
- At the end of "The Crimson Horror", the kids Clara babysits confront her with pictures they found of her from time periods that she couldn't have possibly been alive in (or at least not in her twenties).

Joy refuses to believe it...until during a talk, Harold suggests they go out to dinner "at the place at 6th you like." A heart-broken Joy immediately asks how, if Harold was truly a tortured prisoner for the last decade, he can possibly know such a detail about her life and realizes Ward is right about their father.
- Law & Order: UK: During the prosecution of an accused rapist/murderer, the key witness is a young woman who saw the man lurking around the building where the crime took place (she may very well have been the intended victim had she not evaded him). The man denies it, angrily accusing the girl of lying and referring to her tattoos before covering his mouth in horror as he realizes his mistake. Although the girl's arms were indeed covered with tattoos, she was wearing a jacket while in court. The only way he could have known about her tattoos was if he had seen her previously.
- Million Yen Women: This is used to reveal who the invitation sender is. In an early episode, one of the characters asks for a certain piece of information. Later on, it turns out that the asker should have known that piece of information at the time, which makes the fact that they asked very suspicious.
- The Outer Limits (1995): In "Corner Of The Eye" Father Jonascu realizes something is up when one of the aliens claims his friend Father Royce died of an embolism-just like Carlito, a homeless man who'd tried to warn Jonascu about them.
- Preacher (2016): Lara slips up, mentioning Tulip robbed banks in Dallas, which wasn't part of their conversation.

- In Red Dwarf, Lister is reading Rimmer's diary to the Cat. Rimmer is outraged by this betrayal of privacy, and Lister tries to mollify him by saying he can read Lister's diary if he wants.

Lister: Ah, so you have read my diary.
- Saturday Night Live:
Hello, or as they say here in Hawaii...oh, motherfudge!
- Anytime Donald Trump Jr. and Eric Trump show up nowadays, Don Jr. will be attempting to downplay whatever the Trump scandal of the week is, when Eric will say something that just makes them look worse. Don Jr. then hands something, like a fidget spinner, over to distract Eric.
- A less sinister example once occurred on Weekend Update when Colin Jost announces a contest to see who can guess where in the world a personality is currently broadcasting from. They cut to this personality in the location the viewers are supposed to guess.
- In the Supergirl episode "The Darkest Place", Winn's protests to Alex that National City's newest superhero, the Guardian is innocent of the crimes he's been framed for makes her realize Winn knows Guardian's Secret Identity, and it doesn't take much for him to reveal it to her.
- Supernatural: Castiel eavesdrops on Dean, Sam and Bobby arguing about their suspicions that he's working with Crowley. Bobby suggests that if there's any chance they're dealing with "a Superman who's gone dark side", it's a good time to stock up on Kryptonite. Later, after Castiel convinces them they were wrong about him, he makes one fatal mistake.
Castiel: It is a little absurd, though. Superman going to the dark side...
- In Yes, Prime Minister, Sir Humphrey has a tendency to manipulate Prime Minister Hacker for his own self-serving ends, but on one occasion tries to prevent him from appointing a reformer to the position of Chairman of the Bank of England in order to prevent a massive scandal that would destroy Hacker's government. For once, Humphrey is genuinely looking out for Hacker's best interests, but when Hacker finds himself in yet another awkward situation thanks to Humphrey, he furiously confronts Humphrey, leading to this exchange:
Hacker: I don't understand it, Humphrey. What's your game? Why should you be adamant that I allow another cover-up? What's in it for you?
Humphrey: [Urgent] Nothing, Prime Minister! I assure you, I have no private ulterior motive. I'm trying to protect you from yourself. I'm entirely on your side.
Dorothy: How can we believe that?
Humphrey: Because this time it's true! [Hacker raises an eyebrow; Humphrey realises what he's said] I mean... this time I'm particularly on your side.
- In Dawn of a New Age: Oldport Blues, Sebastian calls out David for attempting to shift blame of his attempted murder to a supposed voice in his head. In the process, however, Sebastian accidentally lets slip about the voice in his own head, belonging to the symbiotically possessive Fesxis.
- In Nan Quest, Henry winds up accidentally outing themselves as the Pilgrim by reassuring Nan that if she gets attacked by the Pilgrim again, she can just escape out the window like she did the last time he attacked. Problem: the other person wasn't there at the time, only Nan and the Pilgrim were, and Nan had never explained how she had escaped to anyone. /tg/ was quick to call them on this:
- Persona 4:
Adachi: We already know Namatame was the one who put 'em all in!
- Tohru Adachi does this a lot. No matter how many times Dojima barks at him, he never knows when to keep his mouth shut. Of course, that's a good thing for the Investigation Team (the protagonists), as it helps them gain a little more ground for the latest would-be victim.
- Late in the game, after guessing out the identity of the killer, the Investigation Team goes to the hospital to interrogate him. While he initially tries to give off some basic and non-specific answers, the continued grilling from the team (and Detective Dojima), finally topping off with a blatant accusation, gets him to blurt out:
- The funniest part about this: As mentioned above, he spent most of the game doing this on purpose, Obfuscating Stupidity in order to manipulate the Investigation Team, only to be exposed when he does it for real.
- The real kicker is that he subverts it earlier on. When Naoto finds Namatame's journal, she remarks on the names of all the victims being in it. Adachi agrees and says that it proves Nametame is the culprit...except that among the victims, Naoto explicitly mentions herself and all of her fellow Persona users that were kidnapped and rescued. They were never linked to the murders, so for their names to be present would be surprising or confusing to anyone...except the true culprit. But it isn't until the much more blatant slip-up above that Naoto fully understands this one.
- In the 1st Degree: If you play the game right, Tobin will end up blurting out information that makes him guilty right there in the courtroom.
- In Catherine Thomas Mutton assumes that Vincent has figured him out and accidentally confesses his involvement when he was never under suspicion in the first place.
- Occurs in Suikoden V after the battle between Barows' army, Godwin's army, and the Armes army. Salum Barows feigns ignorance about Armes being there even though he arranged for them to be there. Then, Euram Barows runs in and practically confesses that they were working with them. Then, he goes a bit further by suggesting using the Dawn Rune which up until then had been thought to be in the hands of the village of Lordlake.
- In Prince of Persia: The Two Thrones, the Prince, obsessed with finding and killing the Vizier, hears a woman scream, and heeds the advice of his dark half to keep going. Farah asks him if he heard it and he says that they should continue, because he is "sure she will be all right." Naturally, Farah realized he heard and is outraged, resulting in him going to save the women in the brothel.
- In L.A. Noire we get Jean Archer who can't seem to help but give information by mistake in the case appropriately titled "A Slip of the Tongue".
- At the start of Azure Striker Gunvolt, Gunvolt is receiving a mix of Electric Torture and A Taste of the Lash. The torturer, convinced Gunvolt has no chance of escape, tells him the Muse, whom Gunvolt was looking for, is aboard a freight train. Turns out Gunvolt has electricity powers and the torture actually helped him recharge his energy. He then escapes with extra knowledge of where to look for the girl.
- In Demonbane, Ennea at first appears to be an ordinary girl, but accidentally outs herself as a sorceress with this exchange:
Ennea: Hahaha! It's so rare to see such a relationship between a mage and his grimoire!Ennea: Oh... oops.
- Used a few times in Professor Layton, usually in the I Never Said It Was Poison variety.
- In Diabolical Box, Flora lets slip that the titular box has a goat on it, even though in its current state it looks nothing like a goat. This causes Layton to point her out as the villain in disguise.
- In Last Specter, when confronting a child about the coin of the raven, they tell Layton they don't know anything about " a coin with a raven's tail on it". Layton says that he never said about about a tail.
- A variation of this is used in Azran Legacy, when Layton is confronting Detective Bloom, having accused him of being the mole and replaced the artefacts with fakes. Bloom responds casually that such an accusation is absurd, and that any one could have replaced them with fakes. Layton then points out how odd his reaction is: The fact the artefacts were fake was only discovered recently and is something only a select few, such as Layton, know. Surely the lead detective on the case should have responded to such a sudden revelation and accusation with at least some surprise, rather then a casual denial.
- In an interestingly meta example from The Elder Scrolls V: Skyrim, even deities can apparently make this mistake. At one point, on a quest to destroy a powerful artifact of the Daedric Prince Vaermina, your NPC companion is in the middle of the ritual to banish it when a woman's otherworldly voice whispers in your head that he's tricking you and that you should kill him before he uses the artifact against you. Since there are at least two female Daedra who can be classified as good or at least non-evil and you might not have heard them yet, an unaware player might be fooled into following these orders (and thus losing a potential ally for the rest of the game)...had she not then added, "Vaermina commands you!"
- Happens in Lego City Undercover when Chase arrests Bucky Butler to take his place in Chan's gang.
Bucky: Why do you keep arresting me?

Bucky: Oh sausages.
- Amnesia: Memories: In Heart World, the heroine is injured from an accident and has several wounds covered by bandages, most noticeably on her neck, arms, and legs. She and Shin head to the café and meet Toma, who asks if her head hurts. Shin points out this exact comment when confronting Toma about being the one that caused her injuries. Most people would be staring at her bandaged neck and ask her about that and not her head, which was specifically mentioned to have not been injured during the accident. This means that Toma must have been the one to find the heroine first after the accident, caused her harm in a way that included hitting her head, and then running away. Depending on the ending the player is obtaining, Toma will either admit everything or deny anything.
- In RWBY, Blake and Weiss spend an entire episode arguing about the White Fang; when Weiss openly declares them to be nothing but a group of liars, thieves, and murderers, Blake snaps and shouts, "Well, maybe we were just tired of being pushed around!", inadvertently revealing to the rest of the group that she's both a Faunus and connected to the White Fang. Cue Oh, Crap! when she realizes that she let it slip and subsequently flees the room.
- In Between Failures, to get Nina off her badgering about starting a relationship with Thomas, Carol tries to change the subject to Nina's Harry Potter Fan Fic. However, Carol forgot that Nina had only sent it to Thomas - Nina quickly figures out that this means that the two already started going out. In a way, this works out, as Nina moves on from trying to get Carol to start dating Thomas to begging for info about their relationship.
- Played for laughs in a Bruno the Bandit flashback story, when King Orenthal of Rothland murders his wife due to his growing lust for Eunyce, Warrior Hottie.
Unnamed court official: Your majesty, th-the queen! She
King Orenthal: Was poisoned by three drops of skull-spider venom placed in her wine?? NOOOOO!!

- El Goonish Shive:
- Mr. Verres once revealed to Tedd, with absolutely no prompting that Grace cannot get pregnant in her hybrid form. Seeing as Tedd and Grace had shown quite a bit of interest in each other already, this new information didn't exactly slow them down.
- When Susan starts Pulling the Thread of Tom's web of lies, she eventually gets him to the point where he yells out "I am a FANTASTIC liar!"
- Catalina is absolutely terrible at keeping her mouth shut. Her relationship with Rhoda is supposed to be a secret, but she continually spills more and more information to Susan until she gives up and covers her mouth. Only the fact that Susan has no clue who Rhoda is saves the secret from getting out.
- In Kid Radd, Captain QB, after meeting with Crystal in a room they think is soundproof to discuss killing Radd, sees Sheena on the way out and asks if she heard any of it. Sheena responds that "like your friend said," the room is soundproof. Thankfully, since QB isn't too bright, he never suspects anything, enabling Sheena to leave without incident and help save Radd.
- Ménage à 3:
- When Zii breaks one of Gary's most prized Transformers and learns that it was a highly rare Overlord, she tries to pin it on a cleaning woman she made up: "Tragic, I know. Poor Overlord... never knew what hit him!" Gary than asks how did she know it was an Overlord.
- Later, Kiley's attempts to reassure Gary about his sexual performance soon have her telling herself to shut up. She does tend to turn into a Motor Mouth when under stress.
- The second variation was seen in Narbonic, when Helen was preparing to tell Dave that he's a latent mad genius.
Helen: There's something I have to discuss with you... Artie made me promise.
Dave: Uh-oh... is this about the sentient meme that took over the net in Blue Sector and keeps threatening to vaporize us via spy satellite?
Helen: No, this isn't about the sentient meme! I didn't even know there was a sentient meme!
Dave: Oh. Good.
Helen: On second thought, let's make this about the sentient meme.
- Sticky Dilly Buns: Ruby doesn't want to admit that she has a libido (and the stress of the denial is pretty clearly getting to her), but Dillon manages to draw her into discussion of the book of yaoi manga which she recently gave him.

- In Yokoka's Quest, Yin, mostly talking to herself, speculates out loud on inconsistencies relating to Yokoka's name, Yokoka's mother, Betelgeuse, and Betel's Village. The trope is mostly subverted, as while Yfa picks up on bits of it note , Yokoka seems oblivious to what was said or any of its implications.
- Girl Genius: Both Zeetha and Oggie have a tendency to blurt out information at inappropriate times.
- In Sword Art Online Abridged, Kirito figured out that Heathcliff was actually Kabaya when he got suspiciously defensive after the players started bitching over the ridiculously glitchy state of the game, with Kirito himself referencing TRON. Heathcliff angrily shouts "Oh, now you've seen TRON" ... leading to Kirito realizing that he was referring to Kayaba asking who had seen TRON when making the Death Game announcement, and getting no answer.
Kirito: Of course I've seen Tro- wait, "now"?
- The Nostalgia Critic realizes that "Ma-Ti" isn't who he says he is because he feels Indians like him are given the shaft in Captain Planet and the Planeteers. This immediately makes NC realize that the Ma-Ti he's talking to isn't who he says he is, because the original Ma-Ti is Brazilian.
- In the Adventure Time episode "BMO Noire", Beemo is playing at being a hard-boiled private investigator while trying to find Finn's missing sock. At one point he asks Lorraine the chicken about the missing sock, and Lorraine "blabs" that she knows that it was Finn's sock that was stolen before BMO mentioned it.
- The Eighties version of Alvin and the Chipmunks had Alvin do this twice in one episode. He has a basketball game coming up, but he won't be allowed to play if he doesn't turn in his book report. He falls asleep and never gets it done, so he plagiarizes one of Simon's and turns that in. Saying Too Much one occurs when the teacher is praising Alvin for his report and asks if he had an interest in the sport. Alvin confirms his love for basketball, but the book report was about a tennis player. She sends him to school court for judgment, but he's overjoyed to find out that Simon is the judge...until Saying Too Much two occurs when he lets it slip that he copied Simon's old book report. Now that Simon knows he's guilty, he has to step down and let them find a new judge.
- American Dad!: In the episode "Escape from Pearl Bailey", Steve's girlfriend Debbie is running for class president against Lisa Silver, but her chances of election are ruined when someone posts a slam page against her. Determining that Lisa and her posse posted the page, Steve sets up an elaborate revenge scheme against them (by having buffalo feces dropped on one, injecting another with fat, and giving Lisa herself an STD); when he admits it to Debbie, however, she tells them point-blank that he's no better than they are and dumps him on the spot. When he's mourning the loss of his relationship with his friends, his friends try to comfort him by stating that Debbie wasn't good enough for her. Then Barry quips that Debbie isn't "fit enough to wear people clothes," the same lame insult from the slam page, which makes Steve suspicious; in response, Snot confesses that they were the ones who posted the slam page in an effort to free up Steve's time, since he had been spending so much time helping Debbie's campaign that he had been neglecting them (of course, they never anticipated Steve would go so far).

The prosecutor then asks how Butt-Head could have known the eggs were rotten, unless he was the one that threw them. Oops.
- In one episode of The Emperor's New School, Kronk tried to scare Kuzco away from a field trip by pretending to be a ghost, telling him to leave so that he couldn't pass class and Yzma would become empress.

- "Daring Doubt" has this happen a few times due to the presence of an amulet that compels its wearer to tell the truth.

But in one interview, while explaining why he'd be qualified, he inadvertently explained that the numerous hearings on the 2012 attack at the US embassy in Benghazi, Libya were primarily a preemptive attack against Hillary Clinton's 2016 presidential campaign, causing much outrage on both sides of the aisle: Democrats* , who already had suspicions in that direction, were outraged that the Republicans actually were using the deaths of four Americans as a cheap political stunt, and Republicans were outraged because nobody from their side was supposed to admit what they were doing. McCarthy dropped his bid in October.
- The original suspect in the 2011 murder of Topeka, Kansas resident Sheila Hachmeister was a mysterious internet boyfriend she had who had been pressuring her to send nudes and partake in BDSM, but could not be found, and likely used a fake profile to chat with her. However, Sheila's son, Jason, made himself the new suspect when he bizarrely insisted that he had never touched the rope used to kill his mother, even though 1) he found the body, told emergency services that Sheila had a rope around her neck, and the dispatcher told him to remove the rope; and 2), his DNA was found on the rope. When pressed about the evidence, he said he was "not a cruel murderer". Then it surfaced that the night after the murder, he had gone to a strip club, asked for a private dance, and asked the stripper how it felt to dance for "a cruel murderer".
- An amusing (for fuzzy values of amusing) incident happened when Stauber/Rampton wrote their book about spin doctors, "Toxic Sludge Is Good For You!". They were pondering about a tacky title and came up with this one. About ten seconds later (spin doctors know more than the NSA) the PR guys from the Toxic Sludge Dept. stormed their office to convince them that toxic sludge is indeed good for you, alerting them there was even much more of a stink going on than they already knew.
