->''There are two kinds of lies, lies with short legs and lies with long noses.''
-->-- ''Literature/TheAdventuresOfPinocchio''

A character has some specific tell, often a particular [[CharacterTics tic]] which gives them away when they lie. Of course, another character is bound to pick up on this.

The TropeNamer, of course, is {{Disney/Pinocchio}}'s nose, which increased in size whenever he lied.

The first step to becoming a ConsummateLiar is to make sure you don't have any of these. These are impossible to hide from a LivingLieDetector. This is how YouCanAlwaysTellALiar. If the signal is ''really'' obvious, the character effectively (though not technically) CannotTellALie.

See also TheTell for characters with a tell that points to their emotional state rather than their honesty.

Not to be confused with a GagNose. And no relation to PinocchioSyndrome.


[[folder:Anime and Manga]]
* In ''Manga/ChronoCrusade'', Chrono realizes something's wrong when Rosette is blackmailed by the villain to go off by herself and follows her. When she asks how he knew something was wrong, he responds "When you lie, you start babbling. I've seen you do it for four years. I know at least '''that''' much about you."
** Interestingly enough, this trope comes into play subtly again towards the end of the manga. When Chrono is trying to hide an ally's death that he can sense in another room, he closes his eyes and forces himself to smile, while babbling to Rosette about how they can celebrate their victory every year together (while she questions him about what's wrong). Eight chapters later, he once again closes his eyes and has a strained smile on his face when he tricks Rosette into [[spoiler:taking his hand so he can temporarily "stop" her time and rush off to fight Aion alone]].
* In an episode of ''Anime/DigimonAdventure02'', TK's brother Matt is making excuses for the current Digidestined one of their sisters, and she promptly calls bullshit, claiming people blink a lot when they lie. "Uhhhhh....*blinkblinkblinkblink*" She promises to take his excuse...for a date, much to his defeat.
** Pinochimon (Puppetmon) in ''Anime/DigimonXrosWars'' has the same quirk as the character he's named for.
* Every time Monmon from ''ZatchBell'' lies, his face will grow longer.
* One episode of ''HelloKitty Fairy Tale Fantasy''[[note]]''Hello Kitty's Furry Tale Theater'' in the U.S.[[/note]] retells the Pinocchio story, with the same results when Pinocchio lies. There's an additional twist, however--when the fairy says she's helped Pinocchio too many times, and she's not going to bail him out anymore, ''her'' nose grows.
** A similar thing happens to Catnip's character in the same episode, except it's her tail instead of her nose.
* In ''Anime/CodeGeass'', Lelouch and Suzaku can tell when the other is lying if they are looking away. Suzaku figures out that Lelouch is lying in his confession of deliberately geassing Euphie to kill the Japanese at the SAZ.
* In ''{{Arago}}'', the titular character has a habit of tugging at his ear whenever he's lying.

[[folder:Comic Books]]

* In ''[[http://www.fanfiction.net/s/8670912/14/Harry-Potter-and-the-Gift-of-Memories Harry Potter and the Gift of Memories]]'' Harry knew that Seamus Finnegan was fibbing about his flying experience because "Whenever Seamus lied, he tended to make grand gestures with his hands as if he were conducting an orchestra."
* In ''[[http://www.potionsandsnitches.net/fanfiction/viewstory.php?sid=2985&textsize=0&chapter=18 Red as Fire]]'' Luna noticed that when Harry lied the left side of his mouth twitched and his voice got a little louder.

* ''Film/TheNegotiator'' has a character use the same logic as the ''{{CSI}}'' example below.
* The creators of ''{{Disney/Aladdin}}'' have confirmed that whenever Aladdin tells a lie, the feather on his Prince Ali hat falls in his face.

* In ''Film/VForVendetta'', Evey can tell that a newsreader is giving a false report if she blinks a lot.

* James Bond ''thinks'' he's figured out Le Chiffre's tell (playing with his poker chips) in ''Film/CasinoRoyale'', but turns out that the one round where he acted on it was a BatmanGambit, and Bond proceeds to lose everything until Felix Leiter bails him out.

* Literature/{{Pinocchio}}'s nose was both a tell that he was lying (an incredibly obvious tell, in fact), but it was also a [[CoolAndUnusualPunishment a way of punishing him for it]].
* Mentioned and described in Creator/DavidMamet's ''House of Games''.
* ''Literature/HarryPotter'': Ron Weasley's ears go red when he's angry or lying.
* Cathy's mother in VCAndrews' ''Literature/FlowersInTheAttic'' plays with her pearl necklace -- or mimics playing with one if she doesn't have one on -- whenever she's nervous or lying.
* In one of ''Literature/PrincessDiaries'' books, Mia's grandmother points out that Mia's nostrils flare when she lies.
* In Robert Sawyer's ''QuintaglioAscension Trilogy'', the titular [[LizardFolk tyrannosaurian race]] literally turned blue in the face if they tried to tell a lie. [[spoiler: Most of them, anyway.]]
* In Creator/TerryPratchett's novel, ''Discworld/{{Sourcery}}'':
-->'''Carding:''' My dear Spelter, you blush when you inadvertently tell the truth.
-->'''Spelter:''' I didn't blush!
-->'''Carding:''' Precisely my point.
** Sam Vimes actually has one in the form of another character. Captain Carrot flinches whenever he hears a direct lie, so when Vimes tries to lie to Vetinari with Carrot in the room, Vetinari just watches Carrot's face.

[[folder:Live Action TV]]
* Ned from ''PushingDaisies'' is a terrible liar in any case (Ned: "The plane was hijacked!" Coroner: "How'd you know that?" Ned: "DNA... ish."), but also gives himself away with his TwitchyEye and [[MotorMouth unrelated babbling]]. Olive's tell is that she answers questions with questions when she's hiding something or trying to lie.
* ''{{Lost}}'', "There's No Place Like Home, Part 1": Jack explains that the fact that his stitches are bleeding means his appendectomy is healing. Kate says, "You know how when most people are lying, they can't look you in the eye? You do the exact opposite."
* There was an episode of ''HannahMontana'' all about this; whenever anyone would mention their own lying tics then she would end up doing it. Giggling and sweating were two of them, but there were more.
* ''{{CSI}}'' example: Catherine was able to penetrate one witness' story by recalling her eye movement: "People tend to look left when remembering, right when creating." It's handy to know, but not infallibly reliable.
* There was a whole ''{{Coupling}}'' ramble on this -- The Prickles, where you freeze and can feel said prickles all over your face ready to burst into rampant blushing; the Blurts, where you try to cover your prickles by blurting out denials; and the Head laugh, where you realize you were speaking too quickly and need to make everything seem alright and overcompensate with the Head Laugh.

** A couple of episodes actually have him say "Lie Mode" before saying something untrue. It's not clear whether or not he realizes he's doing it.
* The whole point to the show ''Series/LieToMe'' is that the main cast has been trained to search for these when suspects in crimes are being interrogated. More specifically, Lightman actually claims in one episode that his tell is that he rubs his forehead while lying. (This was a setup for him to point out another character's, which was twisting her hands.) It's unclear whether he was actually telling the truth about that.
* Used in an episode of ''TheLoneRanger'', where the ranger used a villain's pulse as a lie detector.
* Brick in ''TheMiddle'' has a very obvious tell: he simply whispers to himself "I'm lying."
* In ''{{Titus}}'', Christopher can tell when his fiance Erin is lying to him, because [[YodaSpeak words not flow from her mouth good]].
* ''Series/OnceUponATime'' August isn't quite the convincing liar he would like to be. Then again, [[spoiler: he ''is'' Pinocchio after all]].
* In ''Series/GameOfThrones'', Catelyn makes Bran promise he won't go climbing again, and he agrees. After a moment, she says, "You know something? You always look at your feet before you lie."
* In the ''Series/StarTrekVoyager'' series finale "Endgame", Reginald Barclay has managed to overcome his stuttering by the early 25th century, but when he gets pressed for information of Admiral Janeway's whereabouts by the Doctor, Barclay begins to stammer, which is an indicator that he is hiding something.

* ''CyranoDeBergerac'': Aluded by Cyrano at Act II Scene III, after he has fought one hundred men, Cyrano has a [[ChekhovsGun slight cut on his hand and is talking casually to his friends Ragueneau and Lise:]]
--> '''Ragueneau:''' Have you been in some danger?
--> '''Cyrano:''' [[BlatantLies None in the world.]]
--> '''Lise''' ''(shaking her finger at him):'' Methinks you speak not the truth in saying that!
--> '''Cyrano:''' [[Literature/TheAdventuresOfPinocchio Did you see my nose quiver when I spoke?]] [[ShoutOut 'Faith, it must have been a]]
--> [[PinocchioNose monstrous lie that should move it!]]

[[folder:Video Games]]
* In ''VideoGame/{{Tales of Symphonia}}'', Colette always giggles when she lies. Lloyd notices this when [[spoiler:she lies that she still eats, sleeps, and feels sensation when she is, in fact, turning into an angel.]] Lloyd even says "You always do that fake giggle when you lie!"
* In ''Franchise/KingdomHearts'', it's been noted that whenever Axel lies or is unsure of what he's saying he breaks eye-contact.
** Creator/{{Disney}}'s [[Disney/{{Pinocchio}} adaption of the]] TropeNamer appears in the first game as well, to absolutely ''[[CrowningMomentOfFunny hilarious]]'' effect.
