->''"Could you just jump into that pit, there? That deadly pit? You're saying to yourself, 'Why should I jump into the pit?' I'll tell you why. Guess who's down there? Your parents!

This page, [[IHaveThisFriend if it were about]] Bad Liars, would say that sometimes, but never for comedic effect, a character is unable to lie in a convincing way and comes up with really silly lies that fool no one. It would not point out that children are especially prone to it, because once they get over [[ChildrenAreInnocent their innocent]] [[CannotTellALie inability]] they have little practice. It would not talk about physical tics that give away liars either. And it would ''especially'' never say that this is a reason why KeepingSecretsSucks, because keeping secrets is cool. But this page ''isn't'' about Bad Liars, so it won't. Seriously.

This page is not related to HurricaneOfExcuses or SuspiciouslySpecificDenial. Honest. And InflationaryDialogue is definitely not a specific form of it.

Actually this is ConsummateLiar. [[Series/SaturdayNightLive Yeah, yeah. That's the ticket.]]

[[CannotTellALie Pinocchio]] does not say that this page is a lie and that this actually is for comedic effect, children are prone to it, physical tics do give away the lie, and this IS NOT Consummate Liar. What a riot that Pinocchio is, huh?

If it is obvious they are lying to the audience but it is convincing to other characters, it is BlatantLies.

Below are not examples of Bad Liar. They are oatmeal raisin peanut-butter cookie pizzas.
!!These are not examples


[[folder:Nope, No Advertising Here]]
* Mr. Peanut easily tells that Chet (a squirrel with stuffed cheeks) is lying about what happened to the inventory in [[https://www.youtube.com/watch?v=CWDYkRMy7CI this commercial]] for Planters.

[[folder:Totally Not Anime & Manga]]
* In ''LightNovel/FullMetalPanic'', Sōsuke is a ''lousy'' liar. Every time he tries to lie to the other students at school about how he's [[MostDefinitelyNotAVillain A PERFECTLY NORMAL BOY WHO LOVES DOING NORMAL, BORING SCHOOL STUDENT THINGS]] [[SuspiciouslySpecificDenial AND HAS NOTHING TO DO WITH THE ARMY]], they're hardly ever shown to be convinced. ''And'' he fails at lying when it goes the other way and tries to convince them that he's actually a big, bad inhuman terrorist that's unreasonable and will kill anyone. Interestingly enough, however, when he's lying to a corrupt policeman who's actually ''trained'' in interrogating people, he actually manages to convince him about his phony background story (wanting to fight in the Yami Battle for money and power, and also to buy back a prostitute in Tokyo).
* ''Manga/MahouSenseiNegima'' Negi Springfield is a terrible liar. His SuspiciouslySpecificDenial in the Kyoto arc didn't fool anybody, and Chisame commented on it in the SchoolFestival arc. Chachamaru is also incredibly bad at lying when trying to evade answering a question.
* Usopp of ''Manga/OnePiece''. [[SarcasmMode Yeah sure, you command 80 million men, "Captain"]]. Of course, he tends to ping-pong between this and ConsummateLiar, depending on the RuleOfFunny and RuleOfCool.
** Also Luffy, who has absolutely zero ability for deception...pre-TimeSkip, anyway. Afterwards, he has a ''modicum'' of ability, just enough to barely deceive those who are not completely oblivious or naïve... under certain circumstances... after his crew helps him come up with the lie...
*** In the recent Tournament Arc, Luffy was supposed to conceal his identity while fighting. He wasn't simply bad at lying, but forgot he was supposed to do it every couple of minutes. Cue his new battle cry: "This is a normal punch!" It's telling that, in a universe where Paper Thin Disguises work on everyone but the person's closest friends (and sometimes even then), Luffy's denial fooled absolutely no one.
*** And let us not forget why Sanji wanted to eat the devil fruit that grants invisibility.
--> '''Sanji:''' If I ever got the ability I wanted to use it to '''[[FreudianSlip GIRL'S BATH]]'''. Ah no, I meant I asked myself '''[[CasanovaWannabe GIRL'S BATH]]'''. No, I wanted to use it to benefit the humanity '''[[OverlyLongGag GIRL'S BATH]]'''.
* Nagi of ''Manga/HayateTheCombatButler'' has been known to fall into this. Sending Hayate out with Maria on a false date to throw off a stalker. The excuse she gives for not taking Hayate out herself (despite having fallen in love with him at the start of the story) is that they would be mistaken for just a sibling pair. Even normally clueless Hayate comments on how transparent the excuse is.
* ''Manga/{{Arago}}'' is a borderline case. He can lie ''somewhat'' convincingly -- except that every time he does he starts tugging on his ear. Even after a childhood friend points it out to him (he hadn't noticed). Even when he's running.
* ''Anime/HanaukyoMaidTai La Vérité'' episode 11. Ryuuka is revealed as one when she furiously blushes while trying to claim that she just came along to make a mess.
* Celty from ''{{LightNovel/Durarara}}'' manages to be this ''without being able to speak''.
** Without being able to ''speak''? How 'bout [[spoiler: '''''without even having a head, much less a mouth'''''?]] CrowningMomentOfIrony? Perhaps. CrowningMomentOfFunny? Oh, you bet your bonnet.
*** Celty's lies are usually online, where she poses as a guy. She's so bad at this that nobody even ''knew'' that she was attempting to put on this act.
* In ''LightNovel/HaruhiSuzumiya'', Yuki Nagato is a terrible liar in most ways (due to having [[EmptyShell little imagination]] and being a FishOutOfWater), which can be important since she needs to [[LockedOutOfTheLoop lie to Haruhi often]]. She will pause for several seconds when asked a question she needs to answer with a lie (and even tried to get Kyon to lie for her once). On the other hand her [[EmotionlessGirl virtually unchanging expressions]] help her a bit with this. Compare to Itsuki, who has taken acting lessons and is very imaginative.
** Also, Haruhi herself generally manages to be a pretty terrible liar, especially when it involves things relating to her feelings for Kyon. Luckily (or perhaps unluckily, depending on the way you look at it) for her, they either [[ObliviousToLove pass right over his head]] or he is very, very good at [[SelectiveObliviousness turning a blind eye.]]
* Elsie in ''Manga/TheWorldGodOnlyKnows'' is the TropeNamer for the WildCardExcuse, and makes so many {{Suspiciously Specific Denial}}s that she deserves to be called one.
* Gohan of ''Anime/DragonBallZ''. He's [[BlatantLies totally not Saiyaman!]] Nor is he the Golden-haired Warrior. And he's definitely not the son of Goku!
* In the anime version of ''Manga/{{Bokurano}}'', Yosuke Kirie's pilot mark appears on his face, unlike with most of the other pilots, who could hide it under their clothes. He tells his mother that he hit his head, and Ushiro says she would never believe such an obvious lie.
* ''Manga/MakenKi'': If Haruko's gonna try to convince people that she ''[[BlatantLies isn't]]'' in love with Takeru, it'd help if she stopped calling him, [[AffectionateNickname "Take-chan".]] Or maybe not [[http://www.mangatown.com/manga/maken_ki/c038/11.html try to hold his hand]] [[http://www.mangatown.com/manga/maken_ki/c038/12.html where they can see her.]] OR, if she didn't keep outting herself, like:
-->'''*during girl talk about the guys they like*'''
-->'''Minerva: (referring to Inaho and Haruko)''' "That's... well... I know it's him."
-->'''Haruko: ([[LuminescentBlush blushing]] in embarrassment)''' [[http://www.mangatown.com/manga/maken_ki/c012/21.html "N-NO! IT's NOT LIKE WITH TAKE-CHAN!"]]
-->'''Himegami: ([[DeadpanSnarker deadpan]])''' "We never said "who" it was."
-->'''*Haruko [[BlankWhiteEyes goes blank]], realizing she's done it to herself again*'''
* ''Manga/RaveMaster'': Ruby can't lie to save his life, because he has a bad habit of blurting out whatever he's thinking.
* Early in the ''Manga/YuGiOh'' Manga, Mokuba is like this. He often challenged Yugi to games with dangerous stakes that he rigged in his favor. But he was a bad liar ''and'' a bad bluffer, making it easy for Yugi to tell the games were rigged and exactly ''how'' Mokuba was rigging them. For instance, right before the "Death T" arc, Mokuba plays "Russian Roulette Buffet" with Yugi and Jonouchi, a game consisting of a spinning table, and six plates of food, two of which have poison; to which only Mokuba has the antidote. It's rigged, of course (Jonouchi is poisoned on the first spin), as Mokuba is controlling where the spin lands with a syrup bottle - and ''empty'' syrup bottle - next to him. This - along with his lame excuse as to why it's empty and the fact that Mokuba doesn't seem worried at all - tips Yugi off quickly to how he's doing it, and he wins by tying his Puzzle to the table for the final spin, breaking the bottle with it; having to depend solely on luck, Mokuba ends up with the second poisoned dish and loses.
* In ''Manga/TonariNoKashiwagiSan'' Yuuto mentions that Kotone has difficulties with lying, considering how kind and modest she is.
* In ''Manga/{{Aruosumente}}'', Legna, due to lacking imagination and being stubborn, is really bad at telling lies, and usually doesn't bother, so the one time he does he is immediately called out on it.
* In ''Manga/TomodachiGame'', it's fairly obvious whenever Shibe is lying, as he tends to stutter/look away/generally not be composed enough to seem honest. Unfortunately for him, he's stuck in a DeadlyGame somewhat dependent on his (nonexistent) acting ability. [[spoiler:That said, it's why Yuuichi ultimately didn't suspect him too much of being the traitor in the group, as he just doesn't have the skills to pull it off--along with the fact that Shibe CannotKeepASecret.]]
* ''Manga/MyMonsterSecret'' protagonist Asahi Kuromine has this as his defining trait at the start of the series. He actually ''can't'' lie because he has absolutely no poker face and tends to wear his emotions on his sleeve. So naturally, within the first two chapters he learns that the classmate he has a crush on is a vampire, and has to do everything he can to protect that secret until he works up the courage to confess to her.

[[folder:Editoral Section, NOT Comics]]
* Calvin from ''ComicStrip/CalvinAndHobbes''. His lies tend to outrageous even when you consider that he's a little kid. Trying to blame Hobbes every time he does something bad is a common one, but there are lots of others. Really, the only thing sillier than his lies is that he actually expects anyone to believe them. (As his mother said once when he tried to tell her that aliens had landed outside and were demanding to speak to her as a ploy to get her to leave the cookie jar unguarded, "just how dumb do you think I am?")
** Not just Calvin. Susie is a Bad Liar too. When Calvin decides to cheat on a math test by asking Susie for answers, and when she tells him 12 + 7 is "a billion," even the math-impaired Calvin senses something is up: "That's what she said 3 + 4 was."
** His dad is pretty bad too, although he ''can'' usually fool Calvin. One example:
-->'''Calvin:''' Dad, were there dinosaurs when you were a kid?
-->'''Dad:''' Oh sure! Your grandfather and I used to put on our leopard skins and hunt brontosaurus for all the clan rituals.
-->'''Mom''' ''(after Calvin has left)'': Listen, buster, I think Calvin's grades are bad enough, don't you?
** The nighttime monsters that live under his bed are lousy liars too. Every time he shouts out something like "Any monsters under there?" he's sure to get several replies of "Nope!" or the like. Even Calvin is smart enough not to fall for ''that''.
* Dave from ''ComicStrip/KnightsOfTheDinnerTable'' has no poker face whatsoever. This actually becomes a plot point when Bob and Dave want to conceal their in-game plans from Brian and Sara - Dave actually has to wear a paper bag on his head so they can't glean anything from his expression.
* In ''Comicbook/{{PS238}},'' [[MuggleBornOfMages Tyler]] and [[ArtAttacker Alec]] are back in time and suddenly required to go along with Ms. Imperia's XanatosGambit ([[spoiler:[[MyFutureSelfAndMe on herself]]]]).
-->'''Tyler:''' ''Oh!'' Right! Um, stand back as I use my ''smoke bo''--er, anti-witch...''fog maker!''
-->'''Alec:''' And I'll use this ''magic wand'' that looks like a pencil, [[SuspiciouslySpecificDenial but]] ''[[SuspiciouslySpecificDenial totally]]'' [[SuspiciouslySpecificDenial isn't]]!

[[folder:Most Certainly ''Not'' Fan Works]]
* Common characterization for both Rainbow Dash and Applejack in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' stories, as the characters tend to be bad liars on the show itself.
** Rainbow Dash is bad at lying even to herself in ''Fanfic/TwilightsList'', especially about being nervous. She lies to herself in her inner monologue, while she shows outwards signs of the emotion.
** Rainbow Dash is again bad at lying, even to herself, in ''Fanfic/SpringIsDumb'', as she does various things for herself, and totally not because she needs to apologize to Rarity.
** ''WebAnimation/TurnaboutStorm'':
*** [[WesternAnimation/MyLittlePonyFriendshipIsMagic Twilight and Rainbow]] are so bad at lying that [[Franchise/AceAttorney Phoenix]] can easily tell when they are hiding something from him without the help of [[LieDetector his lie detecting Magatama]].
*** Gilda lies constantly, and never stops to consider if she's contradicting previously established facts. Eventually, even the prosecutor gets fed up with it.
* Shows up in other ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfics as well:
** ''Fanfic/IHaveThisFriend'' is about Twilight going to Celestia, asking for romantic advice on behalf of a "friend" about a pony who sounds suspiciously similar to Princess Celestia. [[spoiler: Ultimately subverted, as Twilight was telling the truth. But Celestia is left with the impression that Twilight just sort of confessed to her, and is now planning some sort of grand romantic gesture.]]
* Elspeth of ''Fanfic/{{Luminosity}}'' is an interesting example: a part of her power is that when she tells the truth, anyone she's talking to knows absolutely that that is the truth. Because she lacks the not-quite-RequiredSecondaryPowers, this makes it glaringly obvious when she's lying because the heavens ''don't'' part to sing that this is true.
* In ''FanFic/OhGodNotAgain'', Ginny is specifically portrayed as being this. When Ron wonders where Ginny got the extra money she was spending on school supplies (which she got from her cut of a completely inaccurate book by Lockhart), she freaks out and [[SuspiciouslySpecificDenial demands to know if he's implying she stole it]]. Harry thinks to himself that the Weasleys were raised to be honest.
* In ''FanFic/TheManWithNoName'', the (10th) Doctor laments his inability to lie convincingly in this regeneration several times.
* ''WebVideo/DragonBallZAbridged''; Vegeta, on the Dragon Radar.
-->'''Vegeta:''' Stupid looking watch you got there.
-->'''Gohan:''' Yes, it tells time...and nothing else.
-->'''Vegeta:''' That's what a watch does. Dumbass.
* Socrates in ''Fanfic/CalvinAndHobbesTheSeries''.
* ''FanFic/DespairsLastResort'' has Kaito and Takara, though the latter is self-proclaimed. It's very obvious that Kaito can't lie to save his life, [[spoiler: which turns out to be exactly what happens. His lies in the first trial are seen through easily, leading him to be convicted as Chiyo's murderer.]]
* Lying is definitely not Brittany's forte in Fanfic/NewReality, as Kratos eventually said.
-->'''Brittany:''' Fan-freakin'-tastic. So [[IKnowYouKnowIknow you know that I know...do you how I know? Do you know that I know that you know-]]
-->'''Kratos:''' Enough. If you're trying to conceal your nervousness, you're doing a terrible job of it.
-->'''Brittany:''' ...Sorry. But really...what tipped you off?
-->'''Kratos:''' Hmph. Were I to list everything, this would take all night.
* ''Fanfic/SecondWind'': Luffy has always been one, both in this story ''and'' in canon, and it's spelled out by Ace in Chapter 24 as the only reason he believes that he and Zoro are from the future:
-->'''Ace''': Oh hell no. You did ''not'' just talk about a future event like it already happened. Luffy, I know you. You suck at lying. You have no talent for it. You can hide the truth, you can refuse to talk, hell, you can even keep quiet as a determined psychopath punches you in the face with spiked gauntlets, but you can't lie.
* Celestia in ''WebVideo/DanganronpaParody'', which is hilarious considering [[VisualNovel/{{Danganronpa}} in the original]], her poker face is legendary to the point of earning her the title ''[[ConsummateLiar Queen of the Liars]]''. Here, she only gets by because everyone else was holding the IdiotBall that chapter, and [[GreatDetective Kyouko]] was elsewhere.
* ''Fanfic/DungeonKeeperAmi'': Archmage Dumat, also a DirtyOldMan, as noted in [[https://forums.sufficientvelocity.com/threads/dungeon-keeper-ami-sailor-moon-dungeon-keeper-story-only-thread.30066/page-4#post-6355761 Skrimishing]]:
--> "So, how much of your time with the crystal ball did you spend trying to catch her sating said appetites?" the spymaster teased.\\
"None," Dumat sputtered.\\
Albrecht knew his old comrade to be a very honest man, who had great trouble squeezing a lie through his throat. The resulting higher pitch sounded much like what had just come from the man's lips. "Well, by all accounts, she is a pretty young woman," the king waggled his eyebrows knowingly at the wizard.\\
Dumat cleared his throat. "I don't like what you are implying," he squeaked.

[[folder:No Chance This Could Be Animated Films]]
* In the teaser trailer for ''WesternAnimation/ArthurChristmas'', an elf found in the North Pole by a wildlife documentary filmmaker goes into detail about every single thing that happens in the trailer while saying that they're not, such as how he's "not" an elf, the man in the sweater who pops up and calls Santa his dad is "not" the son of Santa Claus, and that the North Pole is "not" a place where Santa makes test flights so that he can deliver toys to millions of children around the world ''while a giant red flying saucer that serves as Santa's sleigh flies right over them'', Also saying that there is ''no '' movie.
* Oh from ''WesternAnimation/{{Home}}'' is an unconvincing liar, not helped by the fact that [[PinocchioNose his species tends to turn green when they lie]].

[[folder:Definitely Not Live-Action Films]]
* Jimmy Durante in a scene in ''Jumbo'' attempts to sneak his beloved elephant Jumbo off the circus grounds, only to be confronted by a sheriff, who demands: "Where you going with that elephant?" Caught red-handed, [[RefugeInAudacity Durante blithely replies "What elephant?"]]
** There's another Jimmy Durante movie in which he's guarding the dressing room of the beautiful young singer played by Kathryn Grayson from a pushy fan. "She's got twelve kids and I'm the youngest!"
* From the movie ''Film/ThePrincessBride'':
-->'''Miracle Max:''' You got any money?\\
'''Inigo Montoya:''' Sixty-five.\\
'''Miracle Max:''' I've never worked for so little. Except once, and that was a very noble cause.\\
'''Inigo Montoya:''' This is noble, sir. His wife is... crippled. His children are on the brink of starvation.\\
'''Miracle Max:''' Are ''you'' a rotten liar.\\
'''Inigo Montoya:''' I need him to help avenge my father, murdered these twenty years.\\
'''Miracle Max:''' Your first story was better.
** The last two lines are either an inversion, in that Miracle Max thinks he's lying when he's not, or it's simply that Miracle Max is less pleased by the real story than he was by the lie.
** ZigZagged with Humperdinck. Buttercup believes his lie to let Westley go, but the savvier Westley certainly does not; after she leaves and Count Rugan makes a rather unconvincing attempt to maintain it, Westley tells him, "We are men of action. Lies do not become us." Later Humperdinck does a pretty good of lying about caring for Buttercap and being sympathetic to her feelings for Westley, and seems convincingly saddened that she would consider marrying him [[FateWorseThanDeath to be so awful that she'd rather commit suicide]]. But later when she challenges his claim that he sent out his 4 fastest ships to find Westley, he's not good at covering on the spot and makes it pretty obvious he never sent the ships.
* Charlotte in ''Film/ThePrincessDiaries''.
* ''Film/GuestHouseParadiso'': Eddie is welcoming a new guest into the hotel when there is a huge explosion from the kitchen. When the guest asks about this he answers, "Mice... Basque separatist mice..."
* The young hero of ''Film/TheSorcerersApprentice'' has this problem, which is a major plot element. The titular sorcerer actually says this is a good thing, as good wizards are supposed to be truthful. This doesn't stop him from lying, although he's not that great at it either (sake is not Chinese).
* In ''Film/AGuideForTheMarriedMan'', Robert Morse is instructing Walter Matthau how to successfully cheat on his wife. A series of vignettes are used to illustrate different points. One directive concerns what you do if you are caught: Deny, deny deny!. The vignette is a man (Joey Bishop) who is caught in his own bedroom by his wife (Ann Morgan Guilbert). She keeps asking him what he's doing?, what's going on?, who's that woman? He keeps answering with denials: Nothing. I don't know what you mean. What woman? All the while, the woman is getting dressed, and eventually leaves, he makes the bed and straightens out the bedroom, and finally goes to his favorite chair, lights his pipe and picks up the newspaper. When he's all done, there's no indication that anything out of the ordinary ever happened. She eventually is so disconcerted that she simply asks him what he wants for dinner.
* In ''Film/StarTrekFirstContact'', Data is... simply... imitating the behavior of humans when he gets his new arm of flesh slashed during an escape attempt from the Borg Queen's clutches. Queenie then tells him that he has now learned how to lie. Data's fortunately a very quick learner and outgrows being a Bad Liar to pull off the ultimate fakeout on the Queen later in the movie - it's possible he was faking being a Bad Liar the whole time so the Queen wouldn't be fooled by his lie later on.
* A classic example occurs at the end of ''Film/AnimalHouse''; as the homecoming parade descends into chaos, Kevin Bacon's character, with a forced grin, shouts "Remain calm! All is well!" This later turns into [[MadnessMantra desperate screaming]], before, eventually, he is literally flattened by the advancing crowd.
* In ''Film/ShortCuts'', extramarital lovers Gene Shepard and Betty Weathers are well-matched in being spectacularly terrible liars.
** Gene has had so many affairs that his wife, Sherri, has long since stopped caring, and she tells her sister Marian that she puts up with it because she enjoys hearing the ridiculous lies he spins. For example, to cover up his most recent tryst with Betty, Gene claims to have been dealing with a case involving kids on crack, and when Sherri finds the phone number of party clown Claire Kane (whom Gene pulled over ostensibly for driving too slowly but really to hit on her) in Gene's pocket, Gene claims that Claire is a dangerous criminal nicknamed "the Clown".
** Betty, meanwhile, has two boyfriends going at once, Gene and Wally. She is planning a weekend away with Wally, but tells Gene she is going to Lake Tahoe to see her sister. Gene says her sister lives in Michigan, and she tries to claim this is her other sister - her "half-stepsister" Bunny. She also flips from saying the arrangement was made a week earlier to a year earlier, and avoids answering questions about what Bunny does for a living or whether she is married. Gene then asks Betty's son Chad about seeing his Aunt Bunny, and Chad clearly has no idea what he is talking about; Betty tries to claim that Chad is too young to remember Bunny.
* Caleb from ''Film/ExMachina'' appears uncomfortable and unfamiliar with lying, and doesn't seem to fool Nathan when he does. On the other hand, [[spoiler:he was at least good enough not to give away his ace in the hole until it was too late for Nathan to stop it]].
* Bo Callahan from ''Film/DraftDay'' a few times. The Redskins once attached a hundred dollar bill on the back of the playbook in order to test if quarterbacks actually read the playbook. All of them found the money or admitted they didn't read the playbook. Bo stayed with his story that there was no money.
* ''Film/TheHungerGames'': Katniss Everdeen, according to Peeta. "Never gamble at cards. You'll lose your last coin." [[spoiler:[[SubvertedTrope Subverted]] later on, when she gradually becomes more effective at fooling people -- starting with Peeta himself in the form of their initial romance.]]
* ''Film/{{Anchorman 2 The Legend Continues}}''. Ron Burgundy tries to lie about his BungledSuicide...except he only told the truth in a tone that makes it sound like he is lying.
* ''Film/TheForceAwakens'': Finn's Resistance fighter act is so transparent that it doesn't fool Han for a minute. Before that, Poe calls bullshit on his motivation for helping him escape even more quickly. The only person fooled is Rey, and only because she's nearly as naïve as he is.
** Elsewhere in the ''Franchise/StarWars'' franchise, Han Solo is...not the brilliant liar he seems to think he is. Case in point, his attempt to imitate an Imperial officer on the Death Star, despite that being a job ''he was trained to do'', and which ended with him shooting the console to get out of the conversation.
--->'''Han:''' Had a slight weapon malfunction but everything's perfectly all right now, we're fine, we're all fine now, thank you. How are you? [incredibly pained "man, what the hell did I just say?" expression]
** ''Film/RogueOne'' has [=K-2SO=], whose status as a reprogrammed Imperial droid means that he'd be a very effective infiltrator, if he was actually able to keep up the facade for more than, ooh, eight seconds of conversation.
--->'''Stormtrooper:''' Where are you taking these prisoners?\\
'''K-2SO:''' These are prisoners.\\
'''Stormtrooper:''' [wearily] Yes. Where are you taking them?\\
'''K-2SO:''' I am...taking them, to imprison them...in-- prison.
* ''Film/CaptainAmericaTheWinterSoldier'': Steve Rogers, [[TheCape beacon of morality]] that he is, is a truly terrible liar. Not a single SHIELD employee is fooled for a second by his repeated claims not to know what's going on, and Black Widow even insults him to his face for it ([[TheyFightCrime in an appreciative way]]). He's no better at other kinds of deception, either. His idea of hiding a USB with the fate of the free world resting on it is to put it behind two packs of gum in a vending machine that's being restocked.
** Heartbreakingly subverted in ''Film/CaptainAmericaCivilWar''. While Steve is still a bad liar, [[KeepingSecretsSucks he's capable of deliberately hiding information]]. Despite knowing for two years HYDRA was responsible for [[spoiler: the death's of Tony Stark's parents]], he never told him. Tony is as enraged by this deception as he is by the act itself.
* A recurring them in ''Film/IndependenceDay''. President Whitmore is repeatedly told by his wife that he's a bad liar when he tries to tell untruths. It's implied that his honesty is one reason he was elected in the first place.

[[folder:This Really isn't the Literature section.]]
* ''Literature/{{Animorphs}}'': When called upon to make up a phone number, Cassie comes up with "1234-5678". Marco, who has no problem making up anything ever, chastises her ASAP.
-->'''Marco:''' Eight? [[CriticalResearchFailure You gave him eight numbers]]? Remind me never to be a spy with you.
** He also berates her for using "Creator/CindyCrawford" as a fake name. Though honestly, he and Rachel just lucked out that the interrogator didn't recognize [[Series/TheXFiles "Fox Mulder" and "Dana Scully"]].
** Ax at one point is convinced to take the blame for giving humans the morphing technology to spare his brother the shame, but fails to think up a decent lie about it. When an Andalite captain later ask how he met the Animorphs he replies with the truth: They rescued him from his ship at the bottom of the ocean...using technology he supposedly gave them. The captain catches on instantly.
** Most Yeerks are {{Consummate Liar}}s, what with being able to read their hosts' minds, but that doesn't hold for Temrash-One-One-Four, Tom's original Yeerk who later infested Jake. After finding out that {{Puppeteer Parasite}}s are a thing, it only took Marco one conversation to realize that Tom was one of them. Once in Jake's body, Temrash has such instinctual FantasticRacism toward Ax that the others catch on in about five minutes of him waking up.
* In the ''Literature/AubreyMaturin'' series, Stephen Maturin ponders Sophie Williams' talent for prevarication.
-->'''Post Captain:''' She lies with as much skill as Preserved Killick -- a desperate stare, and her face the most perfect damask rose.
** Sophie Williams is Jack Aubrey's fiancée at this point.
** Preserved Killick is the name of Jack Aubrey's servant. Really.
* In the ''[[Literature/AuntDimity Aunt Dimity]]'' series:
** Lori is most successful at avoiding issues by not mentioning them at all than by telling a lie. In ''Aunt Dimity: Detective'', she jokingly asks Nicholas Fox to teach her to play poker, since he so much better at concealing his feelings than she is.
** In ''Aunt Dimity and the Lost Prince'', curator Mile Craven acts suspiciously when Lori and Bree ask after his former employee Amanda Pickering; his gaze drops and his chatty demeanor abruptly disappears. His discomfiture is related to [[CannotKeepASecret his inability to keep a secret]].
* Billy Bunter of Literature/{{Greyfriars}}. "I say, keep that beast Coker off! I wasn't in his study when he found me there, the suspicious beast! I wasn't after his cake! There wasn't any cake, and I never touched it, and I had hardly a mouthful when the brute came in! I say, you fellows -- ow! Oh crikey!"
* In Creator/RudyardKipling's ''Danny Deever'' -- some interesting weather:
-->''"What makes the rear-rank breathe so 'ard?" said Files-on-Parade.\\
"It's bitter cold, it's bitter cold", the Colour-Sergeant said.\\
"What makes that front-rank man fall down?" said Files-on-Parade.\\
"A touch o' sun, a touch o' sun", the Colour-Sergeant said.''
* ''Literature/{{Discworld}}'' has a tribe of people [[PlanetOfHats who are all]] Bad Liars. People with the gift for lying are considered very valuable in this tribe; [[DoesThisRemindYouOfAnything they are elected at various government and diplomacy positions and wear the glorious title of Liars]].
** In ''Discworld/{{Jingo}}'', Sergeant Colon and Captain Carrot are both really bad at going undercover. In fact, Carrot is such a bad liar in ''Jingo'' that he can't even convincingly keep quiet when someone else is lying. During a briefing at the palace, the Patrician sends him out of the room because watching him twitch every time Commander Vimes opens his mouth is disconcerting.
* ''Literature/TheDresdenFiles''. Harry Dresden admits to being a bad liar (especially in the earlier books), mostly by virtue of just not being able to make his lies sound natural. As the series progresses, he gets somewhat better at being deceptive, mostly by being very selective about what information he imparts.
** In ''Literature/ColdDays'', [[spoiler: Maeve]] gains the ability to lie [[spoiler: after being corrupted by Nemesis]] and hinges her plan on the fact that faeries, in all known circumstances, CannotTellALie. This would be brilliant, except that she has no experience with lying and isn't very good at it, causing her to accidentally say a few things that tip Harry off to what's really going on.
* ''Literature/HarryPotter''. As Snape said, he "has a tendency to wear his heart on his sleeve." He gets better, though. Naturally, the fact that Snape is an accomplished legilimen (telepath) ''does not help'' in this instance.
** A more straight example is Hagrid. In ''Literature/HarryPotterAndTheOrderOfThePhoenix'', Hagrid was briefly questioned by Dolores Umbridge regarding some footprints in the snow. Although he tries to defend Harry and friends by lying about them, it's pretty clear that he's doing an absolutely bad job at it. It still managed to get Umbridge away, though.
* Shelby of the ''Literature/HIVESeries'' tries to pass off as a regular AlphaBitch when first taken to the Island. It doesn't work, but the routine really irritates everyone.
-->'''Shelby:'''Come play poker with us! Wing is cleaning us out with that excellent poker face of his.
-->'''Wing:''' I have a poker face? Wow, I just thought you were really, really bad at this game.
* Wanderer from ''Literature/TheHost'', mostly because Souls (with the exception of Seekers and members of the first wave) never needed to lie.
* ''Literature/HuckleberryFinn'': Huck is occasionally brilliant at spinning yarns to get what he wants. More often, however, he forgets his fake identity, where he's supposedly from, and what he claimed his job was. HilarityEnsues.
* Michael from the ''Literature/KnightAndRogueSeries'' doesn't like to lie, but when he gets into a situation where he's really got no other options, or if he's trying to spare someone's feelings, he'll give it a shot. Since he's so rotten at it though, it makes no difference. However, in a ''really'' desperate situation he can convincingly lie, and because he's known to be so bad at lying no one doubts him in the slightest.
* [[KingIncognito Alek]] from ''Literature/{{Leviathan}}''. Literally ''every time he opens his mouth'' to try and tell a lie, he effs up. It doesn't really help that the people he tries to lie to are ''really'' sharp.
* Terry Brooks' ''Literature/MagicKingdomOfLandover'' series had the gnomes that were incredibly bad liars.
* Myra in the ''Literature/NightfallSeries'' starts out as a bad liar. Prince Vladimir is determined to teach her how to lie better (even though she's the one sent to assassinate him and he knows it) as he loves a challenge.
* The Pigeon from ''[[Literature/PigeonSeries Don't Let the Pigeon Drive the Bus!]]'' is a transparently bad liar.
* Christine in ''Literature/ThePhantomOfTheOpera'', which makes it impossible for her to convince Raoul and her [[ParentalSubstitute adopted mother]] that she is not in any danger from her stalker, and later makes it impossible for her to hide from Erik the fact that Raoul and the Persian are inside his house.
* The protagonist of ''Literature/RumoAndHisMiraculousAdventures'' is this. When he asks the mentor for help, he tries the "[[IHaveThisFriend my friend Urs]] has this problem..." approach, but slips and says "I" instead of "Urs" several times. The mentor is nice enough not to mention.
* In the ''Literature/HonorHarrington'' books, Honor, Sir Webster, and a few other Manticoran officers-cum-diplomats are this. In fact, that's part of the reason they're ''chosen'' as diplomats; their inability to lie well makes their honesty equally obvious.
** Webster in particular is such a terrible liar that when he tries, people think he's just being sarcastic.
* Kate from the ''Literature/KateDaniels'' series is a notoriously bad liar. Except when playing poker, it tends to work in her favor, because when she threatens to kill people with ease and maximum blood loss, they instantly believe her.
** It becomes a plot point in ''Magic Rises''. [[spoiler: Curran keeps Kate out of his masterplan to deal with Lenore, because it hinges upon her reacting with genuine jealousy, anger and distress, and she couldn't possibly fake it. Needless to say when Kate finds out, this bites them in the ass, since she doesn't agree that being a bad liar warrants her heart being broken by the only person she trusts.]]
* According to the squad mechanic, Kell Tainer is a terrible liar in the Literature/XWingSeries.
-->'''Cubber:''' You ever play sabacc?
-->'''Kell:''' A little, but I'm not very good at it.
-->'''Cubber:''' "I'm not very good at it" indeed. My four-year-old daughter is a better liar.
-->'''Kell:''' Well, I lie a little, but I'm not very good at it.
* ''Literature/TheHungerGames'': Katniss Everdeen, according to Peeta. "Never gamble at cards. You'll lose your last coin." [[spoiler:[[SubvertedTrope Subverted]] later on, when she gradually becomes more effective at fooling people -- starting with Peeta himself in the form of their initial romance.]]
* ''Literature/{{Edgedancer}}'' (a novella of ''Literature/TheStormlightArchive''): Wyndle knows that he's going to become Lift's MorphWeapon and doesn't like this fact one bit, but per the rules, can't tell Lift anything about it. So of course he keeps on bemoaning the fact that Lift is going to be hitting people with him, and then tries to convince her that he doesn't mean anything by this, no siree, why would she even be asking? Luckily for him, Lift thinks he's kind of insane.

[[folder:Live-Action TV? That's... somewhere else]]
* This has become something of a running gag for Simmons in ''Series/AgentsOfSHIELD''. It's first demonstrated in "The Hub", when she's unable to come up with a good cover story when a senior agent catches her sneaking into a restricted corridor, and proceeds to attempt several awfully transparent excuses while Skye looks on in absolute horror. "The Magical Place" shows Skye giving her "safe words" to use during telephone calls rather than tell a direct lie, in the hopes that this will help. It doesn't.
** "T.R.A.C.K.S." plays with this trait some more: Simmons claims that it's not that she can't lie, she just can't ''improvise'', and so she devises an elaborate back-story for her undercover character. Unfortunately, she over-corrects quite a bit, ending up going into a massively detailed rant with no provocation.
* Rene in ''Series/AlloAllo'' is also a terrible liar, never more than when trying to explain to his wife why he's embracing one of the waitresses. She however seems to accept his nonsense -- whether she genuinely believes it or just wants a quiet life is never clear.
* On Season 18 of ''Series/TheAmazingRace'', the penultimate leg had Flight Time & Big Easy and Zev & Justin find a flight that would put them in Brazil half a day in front of Kisha & Jen and Gary & Mallory, but when Mallory asked the Globetrotters if they had found a better flight, Flight Time's horrible lie all but gave away that they had, and all four teams got on the same flight, resulting in [[spoiler: Zev & Justin getting eliminated when they struggled on the leg]].
* Over on ''Series/{{Angel}}'', according to Gunn, lying is the "one" thing Fred isn't good at.
* Oliver Queen on ''Series/{{Arrow}}'' is capable of some ridiculous excuses, particularly when it comes to Felicity before he just gives up and lets her in on the secret. He is somewhat better at deceiving his family and friends (not to mention the police) but mostly that's because they write his odd behavior off as PTSD from the island. Lampshaded when Diggle tells him "your BS excuses are getting worse".
* In an episode of ''Series/BabylonFive'', Garibaldi says that Lyta is a terrible liar, which upsets her greatly. [[InformedAbility It's not seen much in the show]], except for one time when she's lying to evil Kosh. He doesn't seem to notice how nervous she is, but Kosh is an [[JerkAss arrogant]] StarfishAlien, so he's probably not good at reading people.
* The characters on ''Series/BeingHumanUK'', save for Nina, are pretty bad liars, particularly George. Worse yet, when the group is in desperate need of a good lie he never steps down and lets one of the other characters take care of it; he always comes up with the lie. It is often answered with skepticism.
-->'''Owen''': What was it?\\
'''George''': What? Oh a... pigeon.\\
'''Owen''': A pigeon?\\
'''George''': Must have left a window open.\\
'''Owen''': Have you got rid of it?\\
'''George''': ''(beat)'' I killed it.\\
'''Mitchell''': You killed it?\\
'''George''': With a shoe.
* Sheldon Cooper on ''Series/TheBigBangTheory'' develops "more tics than a Lyme disease research facility" on his face whenever he tries to lie.
* ''Series/BuffyTheVampireSlayer'':
** In the episode "Anne":
-->'''Buffy:''' You know, I just woke up, and I looked in the mirror, and I thought, hey, what's with all the sin? I need to change. I'm dirty. I'm bad with the sex and the envy and that loud music us kids listen to nowadays.... Oh, I just suck at undercover.
** Buffy has this problem in other episodes. Example, from "Lie to Me":
-->'''Buffy:''' Um, uh... there was a-a cat. A cat here. And um, uh, then there was a-another cat. And they fought. The cats. And... then they left.\\
'''Ford:''' Oh. I thought you were just slaying a vampire.\\
'''Buffy:''' What? Whating a what?
** Buffy seems to subliminally ''want'' to be caught out in her Slayer duties, but the adults around her are too wrapped up in denial. In ''Buffy'' season 4/''Angel'' season 1, when she chases Faith to L.A. and is arguing with Angel after Faith turns herself in, Buffy insists to Angel that she came because he was in danger (Faith ''was'' previously trying to kill him under Wolfram & Hart's employ), but Angel doesn't buy it for a second and accuses her of only coming for vengeance; Buffy doesn't even try to deny that.
** And then there's Anya trying really hard to convince the Watchers' Council that there isn't anything demonic in her origin, no sir.
** Early on, Willow got this role before basically passing it on to Anya.
-->'''Willow posing as her own EvilTwin:''' I'm a bloodsucking fiend. Look at my outfit.
** Then there's Tara. When Spike gets the Buffybot from Warren to use as a sex toy, Tara ultimately decides to tell Dawn that he made it with the intent to play checkers with it. Dawn, of course, isn't fooled for a second.
** Also, when Faith tries to frame Buffy to Giles for a murder Faith had accidentally committed, Giles only pretends to be mad at Buffy until Faith leaves, at which point he reveals he knew Faith did it, since lying isn't one of her strong points. FridgeLogic sets in when he hires her to infiltrate a castle and assassinate a slayer.
** It's just as well that Cordy doesn't sugarcoat the truth, because she can't lie to save her life.
*** Except she did in "Homecoming", when she convinced a vampire she was Faith the Vampire Slayer.
* ''Series/{{Chuck}}'' combines this with NonverbalMiscommunication. Awesome is trying to explain to Ellie where he's been all day; Chuck tries to help him by miming behind Ellie's back, which results in a story about Awesome decapitating a bear he encountered in the park. Chuck has to step in with a more plausible lie.
** Awesome can't really lie to Ellie, but he has no problem lying to other people, even Chuck.
* ''Series/{{Coupling}}'':
** Jeff is a terrible liar. His trademark DiggingYourselfDeeper monologue is often triggered by telling a stupid, unconvincing and ludicrous lie where the truth would actually have been perfectly acceptable...
** Patrick as well, best demonstrated when he accidentally lets slip to Steve that he slept with Jane, then tries to deny it.
-->'''Steve''': Patrick, I know you. You can't keep a lie like this going!
-->'''Patrick''': Course I can. ''Damnit!''
-->'''Steve''': Look, when did this happen?
-->'''Patrick''': What, the lying or the sleeping with Jane? ''Damnit!!''
* In some early episodes of ''Series/CriminalMinds'' [[NerdsAreSexy Reid]] would be reduced to a stammering mess any time he needed to lie. He got better in later seasons.
* Alan Tudyk's character from ''Series/{{Dollhouse}}'':
-->"Those are carrots. Medicinal carrots, that were here when I moved in, and I'm holding... for a friend."
** [[spoiler:Then it turned out that whole thing was an elaborate ruse and the character was actually a ConsummateLiar the whole time.]]
* Josh in ''Series/DrakeAndJosh'' is a very bad liar. In the episode "Dune Buggy", he got talked into lying to his stepmother by Drake about the broken television (which was caused by root beer spilled in it) and got grounded as a result. Drake, of course, reminded Josh that he didn't get grounded for lying, but more for lying badly.
** Averted in another episode where Josh successfully lied to the English teacher to help get Drake out of a raucous English classroom.
* ''Series/DueSouth'': Benton Fraser is a ''really'' bad liar:
-->[''Fraser appears at the table in the restaurant where Insp. Thatcher is with her skirt-chasing former boss, Henri Cloutier'']
--> ''Fraser'': I'm sorry to interrupt your evening, Ma'am, but I thought it prudent to inform you that there's been an emergency.
--> ''Thatcher'': What sort of emergency?
--> ''Fraser'': With your car. It's... [''looking around quickly, then noticing the candle on the table''] on fire.
--> ''Cloutier'': What?
--> ''Fraser'': No, it is. It's burning away. All the other cars feel threatened.
--> ''Cloutier'': Oh, please! You're making that up!
--> ''Fraser'': Well...[''hangs his head''] yes.
* A perennial flaw of the UnsympatheticComedyProtagonist. Basil Fawlty of ''Series/FawltyTowers'' and Series/FatherTed are two major examples. In their case it's to get out of trying situations, only the explanations become so convoluted, bizarre and obviously fake, they needn't have bothered.
* ''Series/{{Firefly}}'':
** Simon doesn't handle being put on the spot very well. Not only does it cause him to fall apart in social situations, but it means he cannot carry a spontaneous disguise well either. When Mal decides at the last minute to force Simon to play the role of a mud buyer in "Jaynestown", he stammers and relies heavily on prompts from Mal. However, when Simon is given the opportunity to plan a scenario (such as "Ariel" or the beginning of ''Film/{{Serenity}}''), he actually turns out to be a criminal mastermind. The only spontaneous situations he handles well are medical emergencies.
** In "Ariel", Simon can see that Mal, Zoe and Jayne will never be able to convincingly lie about being paramedics, so he has to coach them. Jayne requires a lot of coaching, so much that he ends up over-rehearsed; when the conversation with the hospital doesn't go as practised, Jayne insists on spitting out his rehearsed line anyway, much to Mal and Zoe's horror. Fortunately, the nurse at reception is too wrapped up in her own work to do more than roll her eyes at Jayne.
* ''Series/{{Friends}}'':
** Joey:
-->'''Phoebe:''' Ooh, honey. You stink at lying.\\
'''Joey:''' I do not.\\
'''Phoebe:''' Oh really. OK, let me ask you something. Yesterday at the coffee house, I went to the bathroom and when I came back, my muffin was gone. Who took it?\\
'''Joey:''' Somebody opened the door to the coffee house and a raccoon came running in, went straight for your muffin, and I said, "Hey don't eat that! That's Phoebe's," and [[FridgeLogic he said]]... He said... "Joey, you stink at lying." What am I going to do?
** When Rachel was keeping her pregnancy secret, in the Season 7 finale, the audience wasn't supposed to realize Rachel was pregnant until the very last minute, so she lied incredibly well, even in spur of the moment situations. But then in the Season 8 premiere, when the audience ''does'' know Rachel's pregnant, her lying skills go straight down the toilet and the secret is out in no time.
* ''Series/GameOfThrones'':
** Hot Pie. Arya sees through his attempts to lie. He does manage to grow out of this in Season 4, when he glibly dismisses the Starks as all traitors and denies any knowledge of them to Brienne and Podrick until he can be sure he can trust them.
** Cat notes that Bran always looks down every time he lies.
* Maxwell Smart. A RunningGag on ''Series/GetSmart'' went like this:
-->'''Smart:''' ''(Makes an impressive sounding, but very absurd claim.)''
-->'''Listener:''' I find that hard to believe.
-->'''Smart:''' Would you believe ''(insert a less impressive, but still abusrd claim)''?
-->'''Listener:''' No.
-->'''Smart:''' How about ''(insert a claim that sounds pathetic)''?
* In ''Series/GetSomeIn'', [[DrillSergeantNasty Corporal Marsh]] is hopeless at trying to lie his way into good situations or out of bad situations. In "Rugby", he sees joining the rugby team as a way to rub shoulders with the officers and claims to play as a centre forward (which is a position in football, not rugby), while in "Exam Results", he tries to claim that the charges against him for cheating on an exam were motivated by racial prejudice, as although his skin appears Caucasian, the tight curls in his hair reveal his Afro-Caribbean ancestry. Neither lie is believed for a moment.
* Sophia on ''Series/TheGoldenGirls'' typically fell into this when she told people stories about her past, which usually ended with a ridiculous twist. Despite the fact that the other characters rarely believed her, it was often unclear (even to Sophia herself) which stories were true or false, since she had suffered a stroke which affected her memory and also had a bit of a [[MultipleChoicePast mysterious past]].
** Subverted in one episode, when Blanche wants to stop Dorothy using a towel of hers which had 'special memories'. Dorothy assumes it had something to do with Blanche's over-active sex life, then Blanche tells her she actually brought her newborn son home wrapped in it. The story sounds perfectly convincing and moving to the audience - but Dorothy calls her a liar immediately (she was right).
* In ''Series/{{Hannah Montana}}'', Miley invites over Robby Ray's old manager, Marty Klein, to get her father to go back to being famous again. This trope how he greets them.
-->'''Marty Klein:''' Here's handsome young Jackson! And pretty little Miley, whom I have not spoken or had any contact with in any way whatsoever...''(Robby Ray gives a glaring look)''...especially on the phone.
-->'''Miley:''' It's okay, Marty. He [Robby Ray] knows I called you.
-->'''Marty Klein:''' Good cause I'm a terrible liar.
* ''Series/HouseOfAnubis'':
** Nina Martin herself is a notable example, considering how often she has to lie. A good example is telling Victor that she and Fabian were using the telescope one night to "look for a bowling alley" because Fabian "loves bowling". He didn't believe it, and of course ended up looking through the telescope himself to see what they were up to.
** Mara Jaffray is another example, with her most notable attempt being her story about [[FunnyMoments "endangered hedgehogs"]] when she was forced to distract Mr. Sweet in the first season. Unlike Victor in the example above, however, Mr.Sweet actually bought it.
* ''Series/HowIMetYourMother''
** Robin giggles whenever she lies.
** Marshall is a terrible liar, which was even lampshaded:
-->'''Robin''': Marshall, you can't look me in the eye, you're blushing, coughing, and your hands are shaking.
** And strangely enough, Barney in "Tick, tick, tick":
-->'''Barney''': They know!
* Spencer from ''Series/ICarly'' once tried to take Carly out of school to go to the amusement park. When pressed for an excuse, he said he was taking her to a doctor's appointment. With Dr. Rollercoaster.
* In ''Series/TheITCrowd'' Jen asks Moss to make up an excuse to get rid of her unwanted suitor, telling him to just say she is busy when he seems nervous about this. Moss then blurts out to the suitor that Jen is dead, causing the whole office to go into mourning, which ends rather abruptly when Jen walks into her own memorial ceremony...
* ''Series/{{Kaamelott}}'': King Léodagan, afflicted with an extreme case of BrutalHonesty, is a bad liar the very rare times he tries it.
* Some of the suspects on ''Series/LieToMe'' are painfully terrible liars.
%%* Hurley and Daniel Faraday on ''Series/{{Lost}}''.
* The eponymous character of ''Series/{{Merlin|2008}}'' deconstructs this trope. He's a bad liar, but he's such a bad liar that most people believe they can already figure out what he's trying to hide, and they assume it's something embarrassing (most of the cast are under the assumption that he's mentally ill) and thus go the other way. So by being a bad liar, he lies perfectly.
* The title character on ''Series/{{Miranda}}''. The always single and childless woman once tried to get out of one of her mother's setup by claiming to have a sick daughter.
* In ''Series/{{Misfits}}'', Nathan and Simon explain their friend Curtis's absence to his girlfriend by claiming that he had been arrested earlier that day for exposing himself to some Boy Scouts. To be fair, Nathan was only lying to amuse himself, but Simon (who is typically a bad liar anyway) genuinely seemed to think he was being helpful.
* The title character of ''Series/{{Monk}}'' is shown to have this character trait.
** In "Mr. Monk Meets the Playboy," when Sharona asks him if he actually saw the photos of her posing nude; he hesitates for a long time, tentatively says "No," ''then'' blurts out "Yes" as he's walking away.
** In "Mr. Monk and the Red Herring," when Monk first meets Natalie, he blurts out that she's taking birth control pills in front of her daughter Julie, and upon realizing the implications tries to claim he was mistaken and they were really "adult tic-tacs". Natalie later tries to have Monk pose as an expert on fish during an argument with one of Julie's teachers, which doesn't go any better.
* The customs sketch from ''Series/MontyPythonsFlyingCircus'':
-->'''Officer:''' Anything to declare?\\
'''Man:''' Yes... no! No! No! No! Nothing to declare, no, nothing in my suitcase no...\\
'''Officer:''' No watches, cameras, radio sets?\\
'''Man:''' Oh yes... four watches... no, no, no. No. One... one watch... No, no. Not even one watch. No, no watches at all. No, no watches at all. No... [[SuspiciouslySpecificDenial precision watches]], no.
** This reaches its logical conclusion when the man finally confesses to watch smuggling, only to have the Customs Officer not believe his confession because he's such a terrible liar.
*** Perhaps the customs agent is just bad at his job; after all, he lets the obvious smuggler (from Zurich, ''Spain'') through, but immediately tosses a collared priest into a side chamber for a strip search.
** Hitler and his cronies in the "Hitler in England" sketch, whose [[PaperThinDisguise impressively weak disguises]] are not helped by their apparent inability to shut up or keep anything secret.
--->'''"Heinrich Bimmler":''' Oh...and am glad England vin Vorld Cup. Bobby Charlton. Martin Peters. And eating I am lots of chips and fish and holes in the toads on Piccadilly Line, don't you know old chap, vot! And I vas head of Gestapo for ten years.\\
''"Hilter" elbows him in the ribs''\\
'''"Bimmler":''' Ah! Five years!\\
''"Hilter" elbows him again''\\
'''"Bimmler":''' Nein! No. Oh. Vas not head of Gestapo at all! I was not, I make joke!
* Series/MythQuest: Cleo, a teenager who is covertly trying to get information about a myth from a family friend and university professor, keeps blurting out details she shouldn't know. Eventually the friend catches on to TheMasquerade.
* Abby Sciutto from ''Series/{{NCIS}}''. It sure doesn't help that all her coworkers are specialist in PerpSweating and usually know when they're lied to, but even so Abby doesn't like to lie and isn't very good at it.
* Leslie Knope of ''Series/ParksAndRecreation'', honest to a fault, fails miserably at any and all of her rare attempts at subterfuge, in most cases ratting ''herself'' out.
* Ned in ''Series/PushingDaisies''. When asked how he worked out that the VictimOfTheWeek's plane was hijacked just from looking at his body (when what he actually did was resurrect the victim and talk to him), he said "DNA...ish?" In another episode, he and his cohorts pretended to have been sent by the Vatican, and when a nun said that she thought they'd be Italian, his response was "We are. Part time."
* In the ''Series/RedDwarf'' episode where they visit the alternative reality, Holly is seen covered in lipstick after meeting Hilly. When asked "What is that lipstick on your face?", his reply is "What face?"
** And in a different episode, Lister has to teach Kryton how to lie.
** In the episode "Out of Time", Kryten learns what will happen to the crew in the future. He is upset that Lister [[spoiler:is destined to become a brain in a jar]], but can't tell him anything about it. He starts to cry in the kitchen when Lister comes in:
-->'''Lister:''' Everything okay?\\
'''Kryten:''' Oh, yup yup. Those darn onions get you every time!\\
'''Lister:''' What onions?\\
'''Kryten:''' Ah, the onions I'm about to peel. I always get a little emotional when I have to deprive an onion of its skin.\\
'''Lister:''' Don't Nixon me, man! Tell me the truth!
* ''Series/SaturdayNightLive'' had Tommy Flanagan (Jon Lovitz) and his wife, Morgan Fairchild... ''whom'' he's slept with.
* In the ''Series/{{Scrubs}}'' episode "My First Kill", J.D. is trying to tell Dr Cox why a patient isn't being treated, without admitting he just chickened out.
-->'''J.D.''': (InternalMonologue): Now you're going to lie here. Don't be too specific.
-->'''J.D.''': Since one forty-two yesterday afternoon. His wife didn't want him to do it. She's beautiful, by the way; one blue eye, one green eye. She's from Luxembourg. They're both from Luxembourg. They're Luxem ... bourgian.
-->'''Dr Cox''': Where in Luxemburg? [[IAmOneOfThoseToo I spent two weeks there]].
-->'''J.D.''': (InternalMonologue): What are the odds? Just stay vague.
-->'''J.D.''': Outside Mertert, near the German border. They say what they miss most are those lazy summer afternoons on the Mouselle River.
* In ''Series/{{Smallville}}'', Jimmy Olsen is the worse offender, but Clark Kent is also pretty bad. Lana Lang and Chloe Sullivan to a lesser degree.
* ''Series/SonnyWithAChance'': Sonny is a terrible liar. When she lies, her voice usually goes up an octave, and she stammers. The stammering tendency is shared by her boyfriend Chad. Seriously, the cast of So Random must be pretty gullible to fall for the multitude of excuses that Sonny and Chad come up with to hide the fact that they're planning to go on a date. By the time they're all in the limo and have Sonny and Chad cornered, they're either turning a blind eye to get free food, or they are seriously the most gullible people ever to be on television.
* In the ''Series/StarTrekTheOriginalSeries'' episode "Whom Gods Destroy", Garth's lover Marta was a pathological liar (likely one of the reasons she was in the insane asylum where most of the episode took place). She even went so far as to quote the poetry of Creator/WilliamShakespeare, claiming it was her own work. Not even Garth, who was [[AxeCrazy much more insane]] than she was, believed a word she said. (You still kind of have to feel sorry for her [[BlofeldPloy given what he did to her later]], though...)
* In an episode of ''Series/StarkRavingMad'' it's revealed that lying makes Henry so nervous that he starts speaking in a Daffy Duck-esque voice. Ian helps him prepare for a situation where he has to lie by drawing on Henry's experience as an actor in college: by rehearsing lies before hand, Henry can then lie convincingly (albeit in a somewhat hammy fashion).
* Lampshaded by Zack in one episode of ''Series/TheSuiteLifeOfZackAndCody'' where Cody lies to Mr. Moseby as to why the twins were standing in the hallway.
--> '''Zack''': No wonder you never lie. You stink at it.
* Normally, Dean Winchester of ''Series/{{Supernatural}}'' is an excellent liar. He impersonates FBI agents, police officers, park rangers, what have you. But when Dean contracts a Ghost Virus, and becomes a complete and total coward, he also turns into the worst liar north of Mexico.
-->'''Mr. Garland:''' Let me see some ID.\\
'''Sam:''' Of course. ''(Garland looks their ID's over)''\\
'''Dean:''' ''(nervously)'' Those are real. Obviously. [[SuspiciouslySpecificDenial I mean, who would pretend to be an FBI agent?]] That's just nutty!
** Castiel only has a technical understanding of what a lie is. On the rare occasion when he's convinced to lie, it just...fails.
---> '''Castiel''': ''[about Sam's suicide mission]'' It's not possible.
---> '''Sam''': Then humor me.
---> '''Castiel''': Oh, I'm supposed to lie. Uh... ''[smiles unconvincingly]'' Sure! You'll be fine.
---> '''Sam''': Just stop talking.
* An odd RealityTelevision example is Zoe Zanidakis from the fourth season of ''Series/{{Survivor}}''. When Kathy asks her if she's going to vote Kathy out, Zoe pauses for over ten seconds. Then she says no. Oops.
* It is something of a RunningGag that Creator/LeeMack is this on ''Series/WouldILieToYou''
-->[''Lee is having to claim that he used children's cutlery at every meal for a special diet'']
-->'''Rob Brydon''': What was the inspiration for this?
-->'''Lee''': I read it in a book.
-->'''Rob''': Which book was that?
-->'''Lee''': The book of... dieting...
** Another example:
-->'''David Mitchell''':You were 12 or 13, how old was Steve?
-->'''Lee''':Steve was... [He looks at Steve, who is clearly much younger than him] he was... he was... [long hesitation] He wasn't born...
* ''Series/HouseOfCardsUS'': General Brockhart, who is selected as Will Conway's running mate. He's not a natural politician. As a result, lying does not come easily to him and Frank sees right through his poor attempts at deception.
-->'''Frank Underwood:''' Conscience has an unmistakable stink to it, sort of like raw onions and morning breath. But a lie stinks even more when it's coming from someone who isn't used to lying. It's more like rotten eggs and horse shit.

[[folder: You Won't Be Finding Any Music Examples in This Folder]]
* The singer of [[Music/{{Tencc}} 10cc]]'s "I'm Not in Love" is absolutely, 100% insistent that he is not in love with the person to whom he is singing, but every single line of the song plus the singer's delivery indicate that he is completely in denial. According to WordOfGod, this was intentional; the song's primary author Eric Stewart began writing the song after his wife asked him why he didn't say "I love you" more often, and he responded that he felt that repeating those words too often would cheapen their meaning. As a result, he wrote a song "saying 'I'm not in love with you', while subtly giving all the reasons through the song why I could never let go of this relationship." Also doubles as a case of EveryoneCanSeeIt.

[[folder: Rad- Literature! Film! Not Radio! At All!]]
* Arthur in ''Radio/CabinPressure'' goes a funny colour and falls over when he lies. Even when he's sitting down. See, for instance, this dialogue with one Douglas Richardson.
-->'''Douglas:''' Answer this question with a lie. What's your name?\\
'''Arthur:''' Arth...nold...man...er...cat...sir...man.\\
'''Douglas:''' Arthnoldmanercatsirman... That's an unusual name. Tell me, is it made up?\\
'''Arthur:''' Yes, it is. Augh!\\
'''Douglas''': You see, that's the sort of trick question you want to watch for. I'll tell you a secret: the way to lie convincingly is never make something up, just tell a different truth. So, if you have to lie about where you were today, tell them where you really were last week. If you have to give a false name, use a real name you already know. Try again. What's your name?\\
'''Arthur:''' Douglas Richardson!\\
'''Douglas:''' Better. But not quite perfect.
** Needless to say, the advice about telling where you were last week isn't exactly put to good use either.
* In ''Radio/HelloCheeky'', John occasionally suffered this trope, usually while trying to conceal something he had just said about his affair with Barry's wife.
-->'''John:''' Matter of fact, one of my best friends is Barry's wife. I mean...I'm in love with a West Indian dwarf.

[[folder:Most certainly not the Podcast examples repository. Scout's honor.]]
* Podcast/DiceFunk: Rinaldo has a sky-high Charisma score, yet always seems to fail every check related to lying. This culminates in a lie so bad that the episode was entitled "Lie Hard."

[[folder:Tabletop Game examples aren't here at all. Honest.]]
* ''TabletopGame/{{GURPS}}'' splits this into two distinct forms. The "Truthfulness" disadvantage represents a deep aversion to lying, leading to a lack of practice and giving penalties to social skills where deception is required. The "Easy to Read" disadvantage represents very open body language, giving other characters bonuses to read ''you'', including when spotting your lies (but also in other circumstances, all so long as they can see you). One is assumed to be moral, the other more physical. A character with ''both'' is a completely open book.[[note]]There's also an "Honesty" disadvantage, which is actually about obeying the law. Despite its name, it has nothing to do with lying, except in circumstances where lying happens to be illegal.[[/note]]
* In ''TabletopGame/{{Deadlands}}'', the "Lyin' Eyes" disadvantage represents this.

[[folder:Theatre has positively nothing to do with these examples.]]
* In ''Theatre/AnimalCrackers'', when Spaulding is inquiring about the stolen painting, Ravelli (who helped steal it) suddenly comes up with a dubious theory of what happened:
-->"Hey Cap, it come to me like a flash. You know what happened to this painting? This painting wasn't stolen. This painting disappear. And do you know what make it disappear? Moths. Moths eat it. [[TheKillerWasLeftHanded Left-handed]] moths. That's my solution."

[[folder:These aren't Video Games, these are... uh... Reality Games... yeah.]]
* ''VideoGame/TalesOfSymphonia'': The scene where Colette pretends to be an angel delivering judgment on the papal guards. They actually fall for it, though - although the fact that Colette has actual angel wings coming out of her probably scared them enough that they would have believed anything at that point.
** And in ''VideoGame/TalesofVesperia'', Judith keeps saying over and over that she isn't a good liar. Though she never tries to outright lie to people.
* ''VideoGame/PokemonMysteryDungeon'': Chatot, and he really doesn't like it when the other Guild members lampshade it.
* In ''VideoGame/{{Fallout 3}}'' and ''FalloutNewVegas'', if your character's relevant skill is not high enough to pass a dialog check, the response will instead be replaced by an attempt. If the check involves knowledge your character doesn't have, or is an attempt to lie, the dialog choice will involve dialog that's a painfully obvious lie, often with hesitation or stammering. If the required skill is technical in nature, it will usually involve BuffySpeak in place of the technically accurate terms.
* ''VideoGame/{{Iji}}'' blatantly stutters when she lies. Fortunately, it matters little when talking to aliens.
* ''Videogame/{{Portal}}'': SelfDemonstrating/GLaDOS is a habitual liar but her habit of mentioning the truth or creating blatantly obvious fabrications on the fly are readily apparent to the audience.
** In the second game, [[spoiler:Wheatley]] isn't exactly good at this either. For instance, trying to "hack" the neurotoxin control system: "Hello Guv'. Neurotoxin inspector, need to shut this place down for a moment. Here's my credentials; shut yourself down. I am totally legit, from the board of neurotoxin, uh, observers, from the United... Arab Emirates."
** In ''both'' games they tell quite a few lies that suggest they have a very low opinion of Chell's intelligence (like trying to convince her to leap into a bottomless pit by saying a sex-starved boy band is down there). Whether she ''is'' stupid enough to actually fall for most of them [[GameplayAndStorySegregation depends on the player.]]
* ''VideoGame/KnightsOfTheOldRepublic'': Bastila Shan has a problem with her mouth moving when she thinks, but only when talking to a male player character.
** In ''[[VideoGame/KnightsOfTheOldRepublicIITheSithLords The Sith Lords]]'', the HK-50s in [[VoiceChangeling voice mimicry]]-mode are fairly convincing (so long as they don't have to show themselves, obviously). When they use their ordinary voice, however (which is what they do most of the time), they tend to fall solidly here in their interactions with you, on account of a VerbalTic (of sorts) they have in that voice -- describing the statement that is to follow. With adjectives like "Insincere" and nouns like "Fabrication".
* ''VideoGame/RuneFactory3'''s Sofia's lies are made quite obvious as her dialogue will be printed [[RainbowSpeak in red]] to indicate that she actually means the opposite. This is solely for the player's benefit, as the other characters lack the MediumAwareness to see it.
* These crop up a lot during the opening levels of ''VideoGame/LANoire''. Granted the game is mostly about reading people, so it's somewhat a JustifiedTutorial.
* The ''VideoGame/TeamFortress2'' "Meet the Medic" video shows that the Medic is a bit of a bad liar: he claims that ribs grow back, and the Heavy looks unconvinced even before the Medic turns to one of his pet doves and loudly whispers, "No they don't." It's unclear why he even bothered to claim that ribs grow back, because the [[HealingShiv Medigun]] should make it a moot point anyway.
** [[TruthInTelevision Funnily enough, ribs ''can'' grow back if they are reattached.]]
* ''VideoGame/FinalFantasyVI''[='=]s Thamasa is a town full of {{Bad Liar}}s. Everyone in the town can use magic. They try to hide this fact from the outside world, but they do a terrible job of it once the player characters show up. As with many other examples on this page, this is PlayedForLaughs, but due to the CrapsackWorld setting, they once had very good reason to hide their magical abilities from the world, since they were once persecuted for it (they were blamed for the War of the Magi).
** A more comedic example is the town of Zozo, where the first guy you meet says "Zozo? Never heard of it.", and the level's boss says "Good day, gentle folks. Can I be of service? I hate fighting, so I'd better let you pass." right before attacking you.
* Cousin in ''VideoGame/NamcoHigh'', in Tomari's route, is possibly the worst liar in the entire world, although Tomari is too stressed out to pick up on it.

[[folder:These aren't Visual Novels! In fact, Visual Novels don't even exist!]]
* In ''VisualNovel/LittleBusters'', there is a running gag of Rin starting to say something incriminating, realising half-way through, and finishing the word as something that matches the initial sound but is completely nonsensical. Invariably, she is completely convinced she covered her tracks perfectly. For example, when Kengo asks her a question for which the correct answer is 'Kyousuke', she says "Kyoo-ooooouto is a nice place to live."
* In the Prologue Of Grisaia ministory for ''VisualNovel/GrisaiaNoRakuen'' we see how Makina first came to Mihama. At first she's almost silent, but when prompted on her preferences or dislikes she'll give pitifully weak lies because she's convinced that telling the truth will make everyone think she's a spoiled brat and hate her.
* Frank Sawhit in ''VisualNovel/PhoenixWrightAceAttorney''. Not a suprise, as he's the killer in the first ever case in the series, [[ReverseWhodunnit (and that's not even a spoiler)]] and thus serves to get the player used to finding contradictions in witness testimonies. He somehow manages to be [[UpToEleven even WORSE]] when he appears in prison in ''Investigations 2'', though.

[[folder:Web Animation really doesn't belong in here.]]
* In ''Machinima/RedVsBlue: Out of Mind'', this is one of the things that tips the audience off to [[MauveShirt Freelancer New York's]] NiceGuy status.
* In Creator/SamAndMickey's videos, Barbie doesn't do a very convincing job hiding her flaws.

[[folder:I swear these aren't Web Comics.]]
* Thief, Red Mage, and Black Mage from ''Webcomic/EightBitTheater'' are prone to this. Thief, however, has the force of personality to succeed in regularly conning people with his bald-faced lies.
* ''Webcomic/BrawlInTheFamily'' [[http://www.brawlinthefamily.com/comic103.html plays with this]].
* ''Webcomic/{{Chainsawsuit}}'' has [[http://chainsawsuit.com/2008/11/19/strip-110/ Roger the Bad Liar]].
* Elliot of ''Webcomic/ElGoonishShive'' tends to fall into this trope [[http://egscomics.com/?date=2003-12-15 from time to time.]]
* In ''Webcomic/TheEnd'', all Fiah in human guise appear to be bad at both controlling their body language to hide deceptions and recognizing deception in humans, but Endi [[http://www.endcomic.com/comic/ch5-18/ takes the cake]].
* In ''Webcomic/GunnerkriggCourt'', [[http://www.gunnerkrigg.com/archive_page.php?comicID=247 Antimony is sometimes ...]] [[http://www.gunnerkrigg.com/archive_page.php?comicID=211 well, not very good at making things up.]] She also fails at [[http://www.gunnerkrigg.com/archive_page.php?comicID=180 coming up with]] a BondOneLiner.
** Robots are notoriously worse at lying, being fond of the SuspiciouslySpecificDenial.
* In ''Webcomic/{{Kaspall}}'', [[http://kaspall.com/comic/2011/01/16.html Avril Isaac]] is [[http://kaspall.com/comic/2011/01/23.html impressively incapable of keeping a story straight.]]
* ''Webcomic/TheOrderOfTheStick''. Elan the bard is a dreadful liar. Not because he lacks imagination, but because he has too much -- being a {{Cloudcuckoolander}}, his lies tends to get over-the-top. Or be SuspiciouslySpecificDenial. And when disbelieved he just keeps [[DiggingYourselfDeeper Digging Himself Deeper]], [[http://www.giantitp.com/comics/oots0599.html as on this page]]. His bold-faced lies do work from time to time, though, since Sense Motive isn't a very widespread skill in the comic. Elan's girlfriend sums it up best:
-->'''Haley:''' No offense, but you literally can't bluff to save your life. In fact, I think your bluffs usually endanger your life in new and exciting ways.
** O-Chul is a terrible liar. It's not even that the things he says are ''that'' unbelievable; it's just that his world runs on gaming mechanics, and his Charisma score is atrocious, because he started as a Fighter and thought Charisma was a safe choice for his DumpStat -- which naturally turned around to bite him in the behind when he started taking levels in Paladin, a class that runs directly off Charisma.
* In ''Webcomic/TheSilverEye'' no one will tell Enel anything because he is a bad liar. His terrible lying skills are demonstrated in the first chapter when he tells Marcus that an imprisoned character must have escaped via lock picking. Not only was he not particularly convincing, but the key was still in the lock.
* In ''Webcomic/SomethingPositive'', Jason kidnapped Anna's supposedly unworthy boyfriend. Anna followed the trail of drag-marks to Jason's apartment and demanded an explanation.
-->'''Jason:''' Well, we've been having a real problem with Canadian Trapdoor Alligators. They scoop you up in a sack and drag you off to their den. It's horrible.\\
'''Anna:''' I'm impressed. Somehow I thought you'd be a better liar.\\
'''Jason:''' I'm not used to having to lie to a woman I didn't wake up next to.
* A dislike of lying is a recurrent feature of the character of Ruby in ''Webcomic/StickyDillyBuns'', as she actually says herself at one point -- albeit [[http://www.stickydillybuns.com/strips-sdb/try_committing_to_him sarcastically, when refusing to flatter someone else.]] The fact that she's blatantly deceiving ''herself'' over her interest in sex just causes her to blush furiously, and her persistent abrasiveness with her sister Amber may largely be caused by the fact that Amber involved her in deceiving their parents over Amber's career in porn for several years.
* Tom from ''Webcomic/{{Sunstone}}'' has no poker face at all, meaning that Alan sees right through his attempt on behalf of Cassie to hook him up with Anne and tells him straight out "You can't lie for shit!" Though he could probably lie quite brilliantly if he didn't take such pleasure in ''alluding to the truth'' whenever he lies.

[[folder:Don't even bother looking for Web Original here.]]
* Light in the original ''[[WebVideo/DeathNoteAbridgedTioHAndDargonakis Death Note Abridged]]'' by [=TioH=] and Dargonakis. to the point where he blurts out the fact that he's Kira to his father. His father, being [[{{Cloudcuckoolander}} the way he is]], promptly forgets about it.
* Light also does this in ''WebVideo/DeathNoteAbridgedParodyCharlestonVO'' when his mum sees Ryuk.
--> '''Mum:''' Also, is that a demon?
--> '''Light:''' No...... Nah......
* [[WebVideo/RhettAndLink Link]] wanted some time alone, so he lied repeatedly to Rhett in Ultimate Caption Fail 2.
* Cody Giles in ''Literature/AngelOfDeath'' is such a terrible liar that people around him can instantly pick up on any lie he tells no matter how plausible or how little they know him, though his need to conceal his secret identity seems to be forcing him to get better at it over time.
* Nahman of the LetsPlay/GIProz has shown to not be a very good liar, at least in his videos.
* WebVideo/TheNostalgiaChick wasn't fooling anyone when she said she would be the last person to fall for a guy whose face she'd never seen.
* WebVideo/TheNostalgiaCritic's just as bad, stammering and falling into awkwardness when he can't keep a lie going, which is often.
* Jay from WebVideo/MarbleHornets, who at one point gives the same person ''three'' different contradicting stories as to why he's staying in a hotel and carrying a camera everywhere he goes.
* Light in ''WebVideo/DeathNoteTheAbridgedSeriesKpts4tv'':
-->'''Light:''' No one is listening to you, Ryuk.\\
'''Sayu:''' What does Ryuk mean?\\
'''Light:''' Uh, It's my new name for you. It means [[Music/{{Kesha}} Ke$ha]] in Japanese.
** [[spoiler: Higuchi]] is even worse. [[IHaveThisFriend "What if say, hypothetically someone could kill another person with a diary..."]]
* WebVideo/MatthewSantoro is never able to tell a convincing lie, because whenever he lies, he inadvertently gives it away by getting shifty eyes.

* ''WesternAnimation/{{Archer}}''[='=]s Dr. Krieger definitely qualifies:
-->'''Cheryl:''' Wait, how do you know Portuguese?\\
'''Krieger:''' Because I grew up in [[Literature/TheBoysFromBrazil Braz]]... istol County, Rhode Island. Lot of Portuguese in Rhode Island.\\
'''Cyril:''' Where you're from.\\
'''Krieger:''' Born and raised.\\
'''Cyril:''' What's the state capital?\\
'''Krieger:''' ...Dallas?\\
'''Krieger:''' Leave me alone! I am not a Nazi!\\
'''Cyril:''' What about your father?\\
'''Krieger:''' No! He was a scientist!\\
'''Cyril:''' [[StupidJetpackHitler Pretty sure the Nazis had scientists.]]\\
'''Krieger:''' No! That's why we...hurgh...''they'' lost the war! Lack of science!
* Sokka in ''WesternAnimation/AvatarTheLastAirbender''; when caught hatching a plan to escape from [[TheAlcatraz the Boiling Rock]], he responds that the only thing they were hatching was "... an egg?"
** Zuko is also a pretty bad liar (Azula must have gotten all the lying prowess in the family). In "The Southern Air Temple", Zhao sees right through his clumsy story:
-->'''Zhao:''' ''(looking at Zuko's ship)'' That's quite a bit of damage.\\
'''Zuko:''' Yes. You wouldn't believe what happened. Uncle! Tell Commander Zhao what happened!\\
'''Iroh:''' It was incredible!... what, did we crash or something?\\
'''Zuko:''' ''(looking WAY too innocent)'' Yes! Right into... an Earth Kingdom ship.
** According to the "Avatar Extras" (Popups that give tidbits of trivia during a set of reruns) Zuko and Iroh have many talents... lying isn't one of them.
* ''WesternAnimation/TheBrakShow'': Brak's new neighbor and not-so-secret [[ImAHumanitarian cannibal]], Franklin, does this often throughout normal conversation. Appropriately, his [[PinocchioNose nose grows longer]] each time he does.
-->'''Mom:''' Brak, why don't you run along and play with Winston?\\
'''Brak:''' Okay, where's he stay at?\\
'''Franklin:''' At the bottom of the stairs; you can't miss it. However, if you do, you'll fall through the trapdoor and die.\\
'''Dad:''' You have a trapdoor?\\
'''Franklin:''' Of course not.\\
'''Dad:''' But you just--\\
'''Franklin:''' No I didn't.
* Even the dimwitted Tasmanian Devil doesn't believe the claim WesternAnimation/BugsBunny makes that he's a monkey, one of the few animals Taz doesn't eat.
* In ''WesternAnimation/DextersLaboratory'', Dee Dee's ImaginaryFriend, the Koos-A-La-Goop-A-Goop is a BadLiar; sort of. He tells Dee Dee that he's the king of the place that he's from, and while he's clearly lying to impress her, ''she'' is naive enough to believe him for most of the story. (Of course, Dee Dee isn't all-too bright.)
* In ''WesternAnimation/DuckTales2017'', Huey's reply to "Where's Dewey?" is "Who's Dewey?" (Louie had attempted "sleeping", but was undermined by Huey.) Webby is even worse, unable to convincingly lie to her grandmother (either yelling loudly or making up completely unbelievable nonsense). Later, she witnesses Louie ask for a free water cup and filling it with soda when the waitress's back is turned. When Louie encourages her to do the same, she very conspicuously asks for a "free water cup for soda", confusing the waitress and ultimately tipping off the store's manager to Louie's scheme.
* ''WesternAnimation/FamilyGuy'': Brian's explanation of why he's washing the sheets (that he soiled).
-->'''Lois:''' Those look like our sheets and our quilt.\\
'''Brian:''' They are -- I'm-I'm washing them in some fabric softener because last night they were so itchy I couldn't sleep which is why I was downstairs when you asked me if everything was okay... You know, 'cause it was so itchy.
** Peter is often shown to be this, usually in {{Cutaway Gag}}s; in one, he denies having eaten some of the candy in Willy Wonka's factory despite having swelled up into a giant blue ball (like Violet in every adaptation), and in another he farts and tells the guy next to him "Uh, it was you."
* ''WesternAnimation/{{Futurama}}'': After accidentally trashing Hermes' office, Bender's excuse is this:
-->'''Bender:''' Uh, it was ghosts! Big ones! And a tornado!
** He also once turns off the TV when Leela and Fry come in, claiming that he was watching pornography rather than a cooking show.
* In an episode of ''WesternAnimation/GarfieldAndFriends'', Garfield appears on a ShowWithinAShow called ''It Must Be True''. Despite the name, he spends the whole show telling rather absurd LittleKnownFacts, like "There is no such place as Wyoming."
* ''Franchise/GIJoe'': [[https://www.youtube.com/watch?v=OC08RBiRhmM Destro's excuse]] when Cobra Commander catches him and the Baroness kissing ("There was something in her eye") is pretty lame. Even CC doesn't fall for it.
* PJ on ''WesternAnimation/GoofTroop'' is very honest, partly because [[NiceGuy it's just in his nature to want to tell the truth]] and partly because when he's forced into a situation where he wants to lie he always fails. Comes in several varieties: the thought of lying doesn't even occur to him, he looks for a way to technically not lie, he evades direct questions entirely while making it obvious what the truth is from his tone and body language, his lie sounds like sarcasm despite him ''wanting'' someone to be fooled (which, oddly enough, sometimes works), or he comes up with a ridiculous explanation such as "I'm just seeing how hot I can make my knees!" He has been helped by lies before... ''[[HighSchoolHustler Max's]]'' lies.
* From the ''WesternAnimation/GravityFalls'' episode "Boyz Crazy", when Mabel and her friends are [[ItMakesSenseInContext trying to sneak a boy band into the Mystery Shack]].
-->'''[[CloudcuckoolandersMinder Dipper]]:''' And what's in that bag?\\
'''[[{{Cloudcuckoolander}} Mabel]]:''' Uh, money. Money we stole!\\
'''[[AsianAndNerdy Candy]]:''' We are criminals! We will ''cut'' you!
* In one episode of ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' Grim discovers that Morg, the Reaper of Mars, had something to do with the disappearances of the rest of the solar system's reapers. When he asks what happened to all of them, Morg says offhandedly, "Oh, they were vaporized... [[TheCoronerDothProtestTooMuch Complete accidents, every one of them.]]" (This is very hard to believe, seeing as he keeps complete records on why each one was vaporized ''with video footage'' of it. None of the cases looks like an accident.)
* Zim from ''WesternAnimation/InvaderZim'' is full of this, with {{SuspiciouslySpecificDenial}} aplenty.
-->'''Anchor:''' Well, Zim. I guess my first question is...are you an alien? \\
'''Zim:''' [[LargeHam LIES!]] [[NotHelpingYourCase THE FILTHY EARTH BOY LIES!]] ({{beat}}) [[BadLiar I mean, no.]]
* Beezy on ''WesternAnimation/JimmyTwoShoes''. He'll often buckle under pressure and tell people to quit interrogating him, even if they're simply commenting casually to what he is saying.
* Cotton Hill from ''WesternAnimation/KingOfTheHill''. To give one example, he tells Peggy numerous war stories in one episode that make him seem like a hero, but simply don't make sense when you look at them all at a whole. (One of them places him at a location hundreds of miles away from another one that, according to him, took place just a couple of days earlier.) Of course, most of the time, Cotton's perception of reality does seem to be shakey at best... Cotton is such a lousy liar that even his son Hank reluctantly admits that he's a liar, as evidenced from this line in an argument he has with his mother:
-->'''Hank:''' Well that means that one of you isn't telling the truth! (''Slight pause.'') Oh, who am I kidding? I know it's him.
* In ''WesternAnimation/StitchTheMovie'', the pilot for ''WesternAnimation/LiloAndStitchTheSeries'', Jumba tries to convince Gantu that the totally-not-an-experiment-pod is a ping-pong ball:
-->'''Gantu:''' Where are they?\\
'''Jumba:''' They? Who they?\\
'''Gantu:''' The other six hundred and twenty-five experiments.\\
'''Jumba:''' ''(laughs)'' You must have me confused with ''other'' evil genius scientist!\\
'''Gantu:''' ''(notices a pod with "625" inscribed on it)'' What have we here?\\
'''Jumba:''' Uh... is uh... ping-pong ball! Is Earth sport, like tennis but tinier.\\
'''Gantu:''' [[LampshadeHanging You're a bad liar, Jumba]]. Where are the other experiment pods?
* Applejack from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' is defined by her honesty, the Element of Harmony she represents. In the second season premiere, Discord turns her into a liar, but doesn't exactly give her the skills to do it well. Every time she lies, she bites her lip and makes shifty eyes, and when she's actually speaking, she blurts it out in a manner that makes her look like the dumbest pony alive - both in facial expression and [[{{Cloudcuckoolander}} content]]. She gets better at it in the next episode, at which point it's soon resolved. It certainly says a lot about a character's integrity when they have difficulty lying even when being ''magically compelled'' to do so.
** Applejack doesn't need Discord's help to be a bad liar - also in Party of One, she's perhaps the only one to have a decent, plausible, ready-made excuse for not attending the party (that being that she's busy harvesting apples). It still takes her a good few seconds of gazing over the acres of farmland, buckets of apples, and "um"ing and "ah"ing before she finally manages to blurt something out.
** Apparently, it runs in the family. Apple Bloom is also a terrible liar. For example, when she was "explaining" that Granny Smith couldn't come to class because of a family emergency, she involuntarily gave a nervous smile and her eyes started shifting. Apparently, she can cross "poker player" off her list of cutie mark attributes.
** In "Party of One", the rest of the mane six have to come up with reasons why they can't attend [[GenkiGirl Pinkie]] [[{{Cloudcuckoolander}} Pie]]'s party. Rainbow Dash and Fluttershy top the list by claiming they're housesitting for "Harry the Bear" who's on a beach vacation... [[StereoFibbing playing beach volleyball/collecting seashells/collecting volleyballs/playing seashells]]. Rainbow Dash even doodles a watch on her wrist just so she can look at it and "realize" they're late. Of course, since this is Pinkie Pie they're talking to, their excuse is the ''one'' excuse she accepts when she starts to put things together.
* Phineas from ''WesternAnimation/PhineasAndFerb'' in "The Beak". He scratches his ear, stutters and giggles nervously whenever he lies in that episode, and he lies only to Isabella, for that matter. Phineas also lies to Candace in "Out of Toon" & "The Curse of Candace", in the former that the audience loves her as the BigBad, and the latter to prove that she's not a vampire, but ultimately ends up turning her to dust, i.e. killing her.
* An entire episode of ''WesternAnimation/RegularShow'' revolved around Rigby betting Mordecai that he was this, while Mordecai attempted to prove him wrong.
* ''WesternAnimation/SouthPark''. After being accused of toilet papering someone's house:
-->'''Cartman:''' Okay. Last night, all four of us were at the bowling alley until about 7:30, at which time we noticed Ally Sheedy, the Goth chick from the Breakfast Club, was bowling in the lane next to us, and we asked her for her autograph, but she didn't have a pen, so we followed her out to her car, but on the way we were accosted by five Scientologists who wanted to give us all personality tests, which were administered at the Scientology Center in Denver until 10:45, at which time we accidentally boarded the wrong bus home and ended up in Rancho de Fritas Rojos, south of Castle Rock, and finally got a ride home with a man who was missing his left index finger, named Gary Bushwell, arriving home at 11:46.
* ''WesternAnimation/StarWarsRebels'': In [[Recap/StarWarsRebelsS1E04BreakingRanks "Breaking Ranks"]], as part of a plan to steal an Imperial encryption module from Agent Kallus' office, Ezra's new friend Zare Leonis has the job of distracting Kallus so Ezra can [[MindOverMatter telekinetically]] steal the module. Zare does this by claiming he has a delivery of ''used podracer parts'' for the agent. And Zare is so nervous doing it that Kallus suspects something is up.
* [[spoiler:Ruby]] in ''WesternAnimation/StevenUniverse'' turns out to have this trait in "Hit the Diamond", complete with sweating a lot and blurting out very unconvincing statements. Luckily, the people she's lying to are, put bluntly, so stupid they don't notice a sixth member joining their group because their leader ''forgot to count herself'' at roll call, so she still fools them.
** Steven is a little better, but he still cracks under pressure, especially when compared to more experienced liars, like Connie.
--> '''Connie:''' Hey Mom. I was just finishing up my six o'clock violin practice.
--> '''[[MyBelovedSmother Dr. Maheswaran:]]''' You should've been done an hour ago. [...] Hey Steven, how are you doing?
--> '''Steven (sweating and nervously glancing at the thing they're keeping hidden from Connie's mom):''' [[SuddenlyShouting SITTING!]]
* Liar Starscream (whom WordOfGod definitely hasn't named Ramjet...) from ''WesternAnimation/TransformersAnimated'' [[BlatantLies never speaks a word other than the truth. Everything he says most certainly does not sound like a lie.]] [[http://tfwiki.net/wiki/Ramjet_(Animated) This page]] at the [[Wiki/TFWikiDotNet Transformers Wiki]] is not about him, and does not make his lying (which he never does BTW) [[SelfDemonstratingArticle really, really obvious.]]
** Ironically this means he really can't lie -- as long as you keep in mind that what he's saying is a lie, swap it around and you've got the truth.
* The titular [[WesternAnimation/TheVentureBrothers Venture Brothers]] are a prime example.
--> '''Sea Captain:''' Yer... not a good liar, are ya, Dean?
--> '''Dean:''' Mmmmmmaybe...
* Artemis in ''WesternAnimation/YoungJustice''. She looks away, stutters, and visibly has to fish for ideas when lying. This is made kind of hilarious by the fact that [[spoiler:her father and sister are supervillains, and her mother is a reformed one]]. Which is usually what she's lying about.
* Evilina in the ''ComicBook/ZipiYZape'' animated series. Not that it was really her fault: as a result of a failed experiment by Peloto, she suffered mutations of her body every time she lied.
This is not the end of the page; this is the, uhhhh, beginning. Yeah, the beginning - that's right, the beginning.
