[[caption-width:232:Mr. Verres's "ingenious methods to cover up the presence of aliens"]]
->''"My fellow bad guys, I, Lex Luthor, your leader, will speak now about my, Lex Luthor's, plan. My villainous, villainous plan. Question the plan at your peril. Uh... any questions?"''
-->-- '''The Flash''' [[FreakyFridayFlip in Lex Luthor's body]], ''JusticeLeagueUnlimited'', "The Great Brain Robbery"

A character is put into a position where they must act like an X (for example, they are TheMole, or are going through a FreakyFriday). The character, instead of simply acting like an X, attempts to do this by constantly announcing they are an X, like doing things because that's what an X does, and there is not the slightest chance that they could ever not be an X. Did they mention they're an X?

Despite the character's total failure at acting like an X, nobody seems to catch on. Ever. They may notice that the "X" is NotHimself today, and suspect that he/she is not feeling well, but it takes some sort of massive reveal to for them actually put two and two together and come up with anything other than five. Even if they've known that particular X for years. Guess that they were handing out free {{Idiot Ball}}s that day.

Compare MasterOfDelusion, ClarkKenting, BlatantLies and HughMann. If a zombie were to say they aren't a zombie, well then it would [[NotAZombie not be a zombie]], now would it? Kind of a subtrope of BadBadActing, although it isn't deliberate. Tends to fuse with SuspiciouslySpecificDenial.

Named for a line in the ''{{Yu-Gi-Oh The Abridged Series}}'' spinoff ''Crapsule Monsters''; "My name is Dr. Alex Brisbane. I'm definitely not a villain."

* Sousuke does this in the ''FullMetalPanic!'' novel ''Dancing Very Merry Christmas'' when masquerading as a ship hijacker. Naturally, the hostages have a bit of trouble taking them seriously.
-->'''Sousuke:''' Anyway, we are a cruel and unusual terrorist organization that will not show mercy towards women and children. Resistance is death!...Though our guns are loaded with rubber stun bullets, they are enough to make those opposing us cry-
-->'''Kurz:''' No, they're real bullets, remember?
-->'''Sousuke:''' Oh, that's right. These are brutal slab bullets. They will kill a target in one shot. I am not lying.

* LegionOfSuperheroes had a storyline involving shape-shifters Chameleon Boy and Ronn-Karr sucessfully infiltrating each other's teams. [[spoiler:Both were telepathically conditioned to believe they were who they were imitating, meaning both did it TOO well - Cham, imitating Persuader, went on a homicidal rampage, while Ronn-Karr, imitating Superman, helped bring him down.]]
* A [[http://www.airshipentertainment.com/buckcomic.php?date=20090409 scene]] in a ''[[BuckGodotZapGunForHire Buck Godot: Zap Gun For Hire]]'' comic has Buck disguised as an alien Pog, sauntering down the street singing a song about how he's just a Pog, no, really. Mind you, in this instance having the disguise fail is actually [[XanatosGambit part of the plan]].
** For context, Buck Godot is at least eight feet and probably a half ton of muscle, bio-engineered for life on heavy gravity planets. Your typical pog may, generously, top four feet.

* In ''ThisIslandEarth'', a dinner conversation with Exeter quickly makes it clear he's not from Earth. When it was chosen to be the experiment for ''MysteryScienceTheater3000: TheMovie'', Tom Servo repeatedly riffs on this part, concluding, "Then I ram my ovipositor down your throat and lay my eggs in your chest. But I'm not an alien!"
*From ''TheLostSkeletonOfCadavra'':
--> "Sometimes my wife forgets she is ''not'' a space alien."
*The otherwise forgettable ''Corky Romano'' gives us this wonderful gem from the titular character attempting to infiltrate a gang of skinheads: "I was wondering if I could purchase some heroin and then we could go out and commit some hate crimes and stuff."
* ''Cats And Dogs'': "Yes, I am your employer, Mr. Mason. NOT an evil cat bent on taking over the world."
* Lampshaded in BedknobsAndBroomsticks.
-->'''Villager''': It said on the wireless to paint out the sign posts in case the Nazis drop in!
-->'''British officer''': I'm not a Nazi!
-->'''Villager''': That's what you'd say if you ''was'' a Nazi, isn't it sir?

[[folder: Literature ]]

* In ''MoreInformationThanYouRequire'', John Hodgman makes it very clear that he ''does not'' have an elephant's brain pickled in a jar.
* In ''WarriorCats'' Hawkfrost manages to badmouth his superiors and abuse his sister, as well as occasionally lapse into a random world domination rant, without anyone taking much notice (Well, except for Squirrelflight and Leafpool). At one point he even yells about how one day he will be in charge ''in public'', and yet no one even looks his way. Even after he helps organize a failed coup d'etat in ''Starlight'', everyone ''still'' loves him.
* WinnieThePooh pretends to be a little cloud when he tries to use a balloon to steal honey for a beehive. This includes having his friend Christopher Robin walking back and forth below him with an umbrella and loudly proclaim that it will be rain soon.
** I'm not sure about the novel, but in the Russian cartoon Winnie even went as far as ''singing a "little cloud's song".''
*** I can hear parts of the English language version of that song in my head. I used to listen to that story on a record.
**** "Oh, I'm just a little black rain... cloud... hovering under the honey tree. I'm only a little black rain... cloud! Pay no attention to little me. Everyone knows that a rain... cloud! Never eats honey, no not a bit. I'm just floating a-round over the ground, wondering where I will drip!"

[[folder: Live Action TV ]]

*In ''SaulOfTheMolemen'', Saul skins a moleman and uses the skin as a disguise to infiltrate the moleman village. He spends the day shouting, "Grunt grunt! I'm a moleman, just like you!". No one catches on, but Saul is still beaten up, as the moleman whose skin he wore owed money to others.
* ''BuffyTheVampireSlayer'', "Doppelgangland": Willow (well, Season 3 Willow, anyway) [[IAmHeAsYouAreHe pretending to be her vampire duplicate]] was doomed to failure. "I killed her. And sucked her blood, as we vampires do." She lasts all of five minutes before the others catch on.
** And her vampire duplicate is equally pathetic at passing herself off as the human Willow--though far more successful, because she's talking to the [[TheLibby ever self-absorbed Cordelia]]. "Why don't you let me out, 'cause I'm... so helpless." In fact, there's an enormous distinction between Willow, vamp Willow, Willow posing as vamp Willow, and vamp Willow posing as Willow. This was the ep where this troper realized Alyson Hanigan could really act.
** On the other hand, the Scoobies were completely oblivious to the true nature of the [=BuffyBot=] in her first appearance, despite stilted dialogue along the lines of "I wouldn't keep a secret from you, Willow. You're my best friend. You're recently gay." Buffy was understandably irritated.
*** Yet another ''[[BuffyTheVampireSlayer Buffy]]'' example: when [[spoiler: [[EvilCounterpart Faith]]]] exchanges bodies with Buffy, she spends about three minutes practicing saying 'Because it's ''wrong'' ' very emphatically and with different inflections in front of a mirror. It's amusing.
****She [[IronicEcho later says this seriously]] in a case of {{becoming the mask}}
* ''{{Angel}}'' also played on this in the episode "Guise Will Be Guise", in which Wesley found it necessary to impersonate Angel. When his cover was blown, he tried horribly to keep up the facade.
* In the first episode of the new ''DoctorWho'', Rose's boyfriend Mickey is replaced by a plastic replica. Rose begins to wonder what's the matter with Mickey when he keeps addressing her as "sweetheart/babe/babe/friend/sugar/sweetheart".
** Subverted in a later episode when [[spoiler:Cassandra takes over Rose's body. Of course the Doctor knows something is wrong, but he jumps to the wrong conclusion.]]
** The teenage "son" from the Family of Blood spends two episodes walking around looking ''as suspicious as is (in)humanly possible.'' [[RefugeInAudacity It only works because he pulls it off in such a magnificently creepy way.]]
* On an episode of ''{{Charmed}}'', this trope is subverted when Cole immediately notices that Paige and Phoebe have switched bodies. He doesn't tell Phoebe that he noticed until after he has made a move on her whilst she was in Paige's body. OrSoIHeard.
* C'mon, wasn't Simon acting as Mal's boss in "Jaynestown" like this?
--> Simon: Yes? (playing up role) I mean, I make the decisions around here, uh-- employee... (to Foreman) I employ him. He is a person I employ. I'm the boss.
* Subverted in, of all things, ''{{Star Trek}}''. In "Mirror, Mirror," (you know, the episode with the evil parallel universe where everyone has a beard), the prime-universe crew members manage, with great difficulty, to pass themselves off as their evil counterparts. After reversing whatever NegativeSpaceWedgie dumped them in the evil universe and returning home, they briefly worry about the damage that their evil doppelgangers might have caused, only to discover that [[TheSpock Spock]] immediately noticed their odd behavior and confined them to the brig five minutes after their arrival.
* Blackadder the Third uses this trope in the episode "Duel and Duality". Blackadder plays George so that he can participate in a duel with Wellington. Baldrick is confused by, as Blackadder says, "Two people who you know well have exchanged coats and now you can't tell which is which." George ends up failing utterly to be subservient ([[FailureIsTheOnlyOption as he usually does]]) and Blackadder displays tactical genius, [[RetCon advising Wellington]] to station Nelson in Trafalgar, while the real George would have been confused even by the explanation of where he put his men. In the end, even George's father doesn't recognize Blackadder as an impostor (perhaps [[JustifiedTrope justified]] in that he's mad).
** Also played with in the episode "Bells" in Blackadder II. Kate disguises herself -- rather obviously -- as "Bob." Blackadder has been handed the IdiotBall here without question, as he generally tends to be an OnlySaneMan character but, somehow, fails to recognize her for a girl. Cue much agonizing as Blackadder realizes he's [[HoYay falling for a boy]].
*** Kate reprises her role in Blackadder Goes Forth episode "Major Star", again as "Bob." This time, however, Blackadder is the only one who ''does'' realize she's a girl, which makes more sense for his character. This does not, however, mean that the ''other'' characters get handed the IdiotBall, as they generally act this stupid on a day-to-day basis (one memorable scene has them ''standing up'' in a ''minefield'' just to discuss how stupid they are). This is perhaps the only example, however, where the [[SuspiciouslySpecificDenial denial]] part of this trope comes in, as she says, "Oh no, sir, I'm not a girl! I understand cricket! I fart in bed! Everything!" in a breathy, high voice.
* ''Played straight'' in BattlestarGalactica. During Simon's first appearance, he spends his entire first scene insisting to Starbuck that he's human, even using the trope name (with "Cylon" in place of "Villain," of course). Starbuck's too disoriented to notice, but the audience... isn't.
** {{Word of God}} tells that they figured the audience would pretty much guess that Simon was a Cylon. So instead of trying to hide him being a Cylon, they tried to build up the suspense by making it unclear what Simon really intended to do with Starbuck and what the "hospital" actually was.

[[folder: Video Games ]]

* In ''StarControl II'', one of the many PlanetOfHats species in the game comes under the [[{{Brainwashed}} mind control]] of a malevolent being, who stiltedly attempts to impersonate their particular Hat when encountered by the player. Naturally, the player is expected to not be stupid and investigate.
* This is the key mechanic for an entire ''level'' in ''{{Psychonauts}}'', "The Milkman Conspiracy", where the player must collect objects being used by a series of trenchcoat-clad [[strike:"government operatives"]] plumbers, road crew workers, gardeners, ''housewives'', ''grieving widows'', and assassins, among other, increasingly unlikely roles, and use them as a PaperThinDisguise.
** The G-men tend to use the props in very interesting ways too. The gardeners do a sword-swallowing routine with their hedge clippers and the grieving widows play invisible golf with their flowers.
** Sample dialogue: ''I am a Sewer Worker. The finest sewers are found in Paris, France. Although I often smell of excrement, I perform a valuable public service''.
*** And, because this particular troper lacks the discipline to restrain his quoting urge... ''In time my husband will desire me less sexually... but he will always enjoy my pies''.
** There's also Crispin Whytehead, the inmate running the asylum, who explains that he is an orderly, [[SuspiciouslySpecificDenial not an impostor.]]
* In ''PhoenixWrightAceAttorney: Trials and Tribulations,'' Furio Tigre's impersonation of Phoenix consists of having spiky hair and declaring himself to be Phoenix Wright. Despite his otherwise completely different appearance, his noticeable accent, and his wearing a fake attorney's badge made of ''cardboard'', he fools an entire courtroom, including a judge, prosecutor, detective, and defendant who are all familiar with Phoenix. Phoenix himself is, of course, not amused.
** There's a possible {{Lampshade Hanging}} on this, after hearing the excuses Tigre gave to Maggey ("He said he took a trip to Hawaii"):\\
[-'''Phoenix:''' I can see why he managed to fool everyone.-]\\
That is if we take that as part of his usual tendency to Snark.
***''Kind of'' justified in that Tigre made continued threats to anyone that implied he was ''not'' Phoenix Wright. And he's kind of scary, according to, well, everyone in the courtroom.
**** Except Godot. Godot was calm the whole time. [[MemeticMutation This troper thinks Godot is a pretty cool guy. Eh drinks coffee and DOESN'T AFRAID OF ANYTHING.]]
*** Also Godot was the only one NOT fooled, however he didn't say anything as he wanted to spite Phoenix
*** Also didn't help that Godot didn't do the case where Tigre faked his attorneyship. Apparently, [[WarmupBoss Payne]] did that one.
* At one point in ''PaperMario: The Thousand-Year Door'', a shape-shifting ghost called [[spoiler:Doopliss, but [[{{Rumpelstiltskin}} it won't help you]]]] assumes Mario's identity and runs off with all of his party members. Aside from a few party members pointing out his somewhat different personality, they buy his impersonation without question. (In a MythologyGag, Mario is a HeroicMime in this game, while the ghost loudly proclaims that he is Mario and shouts phrases from [[SuperMarioBros Super Mario 64]] to prove it.)
**Somewhat justified in that [[spoiler:Doopliss did the Martian Manhunter trick mentioned above and changed places with Mario when they defeated him, leaving Mario unconscious and going back to town with the others. Being a doppleganger, he has a perfect disguise, at least until he opens his mouth.]]
*** [[spoiler: And Mario's appearance changes as well. He turns black and shadowy.]]
* In ''[[SamAndMaxFreelancePolice Sam and Max]]: The Mole, the Mob, and the Meatball'', Ted E. Bear's [[SuspiciouslySpecificDenial Mafia-Free]] Playland and Casino is a Mob-themed [[SuckECheeses Chuck E. Cheese's-esque arcade/restaurant]] that doesn't seem to try very hard to convince the outside world that it's [[LegitimateBusinessmensSocialClub not a front for the Toy Mafia]].
**Then there's the ''theme song'', which is [[http://www.youtube.com/watch?v=xLVclnItahk catchy as hell]]:
--->''Ted E. Bear's is oodles of fun\\
Slots and sandwiches and poker and guns\\
And look, no mobsters, nary a one,\\
Just you and me and Ted E. Bear!''
* Not a villain, in ''SuperRobotWars'' the pilot Rastel Feinschmecker is Most Definitely Not Elzam Branstien or Rai's brother. May overlap with TheGogglesDoNothing, as he trys to use them to ClarkKent. No one is fooled
** He's definitely not a villain.
* ''RatchetAndClank 3: Up Your Arsenal'' had Ratchet going undercover with the Tyrrhaguise, and loudly proclaiming himself to be "certainly not a Lombax". [[spoiler: Yes, he's a Lombax.]]
* [[http://www.youtube.com/watch?v=mxn-kpHuB9g This guy is totally not a spy]].

* Belkar the halfling got on stilts to disguise himself as a human in ''OrderOfTheStick''.
-->'''Belkar:''' Hello, fellow Medium-sized creature! How are you enjoying being Medium-sized, like me, on this lovely day?
-->'''Man who looks suspiciously very much like [[BadassGrandpa O-Chul]]:''' Just fine, thanks for asking!
**Also, Nale disguising himself as Elan. Though his repeated statements of "I'm Elan" don't raise any eyebrows since that is deemed [[CloudCuckooLander in character]] for Elan. Nale's high bluff skill also helps. Example:
--->'''Sabine:''' He was just speaking to me, a police officer, about his brother Nale's treatment in prison.
--->'''Nale:''' Right! Because I am Elan, and I am foolishly and inexplicably merciful to enemies who would gladly butcher me, against the better judgement of my allies.
--->'''Vaarsuvius:''' Hmmm. Well, that certainly is one of your more puzzling qualities. Very well.
*** On the other hand, immediately after that exchange, Vaarsuvius reveals that he's noticed that the two had been making out (incidentally, Sabine's "police officer" form was male).
* [[http://www.bobandgeorge.com/archives/index.php?date=060820 This]] ''BobAndGeorge'' comic.
* In ''GunnerkriggCourt'', the Robots try to hide their presence from the humans by labeling their secret entrance and their spare part storage room "Boring Door" and "NO spare robot parts", respectively. Appropriately enough, Annie adopts the same strategy (in conjunction with a PaperThinDisguise) to sneak past [[TheGuardsMustBeCrazy Doorbot]]:
-->'''Antimony''': We are looking for a particular robot. A... ''fellow'' robot. Because we are also robots.
** Because clearly she's a robot...
-->'''Antimony''': Also robots never lie.
* [[http://www.galactanet.com/comic/view.php?strip=646 Lord "Smith"]] is Most Definitely Not [[CaseyAndAndy Lord Milligan]].
* In ''TerrorIsland'', [[http://www.terrorisland.net/strips/183.html Theorem 183]], Demon-Jame tries to pass himself off as Jame.
-->'''Demon-Jame''': Yes, I am your friend. I run a non-demon restaurant here in your space-time manifold, of which I am a native.
*In [[http://www.nuklearpower.com/daily.php?date=080531 these]] ''[[EightBitTheater 8-Bit Theatre]]'' [[http://www.nuklearpower.com/2008/10/16/episode-1047-the-ol-180/ strips]], [[HumongousMecha Warmech]] is Most Definitely Not A Robot.
*[[http://amazoness.co.uk/10.htm This]] ''Amazoness!'' strip. Ekphobippe is a master of disguise.
* [[RPGWorld RPG World]] subverts this mightily, by having a character who looks almost exactly like the main villain show up out of nowhere and ask to join the hero's party for no real reason. Only one party member suspects that he might actually be hiding something, but no one believes her... and then it turns out she was wrong and he actually ''is'' a good guy who just happens to look like the villain.
* In ''ElGoonishShive'', all you have to do to convince everyone that you're a normal, everyday human being is to wear a T-shirt that says so on it. In fact, Tedd's father makes a ''living'' covering up supernatural or alien entities in such a manner, as seen, for example, [[http://www.egscomics.com/?date=2003-02-15 here]].
* Jymre of [[http://www.webcomicsnation.com/thorsby/destiny/series.php Hitmen for Destiny]] is probably the worst shapeshifter of all time. He doesn't bother to try to act like the people he's impersonating, and when questioned, he panics severely.
* [[http://www.penny-arcade.com/comic/2005/8/17/ This]] PennyArcade strip features a Most Definitely Not A People-Possessing Ghost.
* In Dorothy Gambrell's guest strip for ''ScaryGoRound'', The Boy shows Erin some kind of unidentifiable...thing he's found. He keeps it behind a shed, with a sheet over it, and a handy label on the sheet which reads: "nothing".
* In ''TheLastDaysOfFoxhound'', Ocelot and Mantis try to pass off an unwilling Octopus as Liquid for a possession scheme by Liquid's ghost (ItMakesSenseInContext) by [=ODing=] him on Liquid's blood and having Mantis brain-scramble him into thinking he's Liquid. Although the intention differs, the result fit the trope perfectly as Octopus starts rambling about how he beats up all the enemy people and hates dominant genes.

[[folder: Western Animation ]]

* ''JusticeLeagueUnlimited,''' The Flash [[http://www.youtube.com/watch?v=KyYOuuRmQp0 posing as Luthor]], as mentioned above. Two people seemed to have caught on, but kept it to themselves for their own reasons (Gorilla Grodd, who wanted to see him squirm, and Tala, who liked "new" Lex better. Especially in bed...). The rest assumed he fried his brain trying to MindProbe Grodd.
** A rare heroic example of a subversion from the same series: Gorilla Grodd's Secret Society has apparently defeated the Justice League. Clayface asks, like any reasonable villain would, why they aren't just going to kill them. Grodd, with his newfound appreciation for showmanship, insists they do it publically...but at the pivotal moment, it turns out Manhunter took Clayface's place; the "Manhunter" the Secret Society captured was in turn actually Clayface. J'onn being a psychic probably helped, though.
* In ''TeenTitans'', Starfire and Raven, having temporarily lost their ability to fly, seek alternative transportation on a bus full of villains. They beat up two and take their clothing. Starfire's horrible acting goes almost completely unnoticed by her audience. What gives her away is the use of an alien version of "God bless you."
* The episode "Fear Of A Bot Planet" in ''{{Futurama}}''.
-->'''Guard-bot #2:''' Be you robot or human?
-->'''Leela:''' Robot... we be.
-->'''Fry:''' Uh, yup. Just two robots out robot-ing it up!
** Also subverted in another episode which features Flexo, Bender's identical brother who only differs in having a goatee. Fry and Leela then find a Bender-like robot who constantly hides his chin behind a pullover or a map, so they assume it is Flexo.
---> '''Fry:''' Hey Bender!
---> '''Robot:''' Yes, it's me...''Bender''
*** The twist is that it really is Bender.
** Also used in another episode featuring Flexo, in which Bender tries to impersonate him, going out of his way to "act" and "sound" like Flexo -- the joke being that Flexo doesn't just ''look'' exactly like Bender except for the goatee, he acts and sounds exactly like Bender except that he's an all-around decent, nice guy.
* ''RobotChicken'': In an ''{{A-Team}}'' spoof, Face attempts to infiltrate the criminal underworld by announcing "Greetings. Is this where the thugs and/or criminals hang out? Because I too am a thug and/or criminal." He is recognized immediately.
* In an episode of ''RockosModernLife'', Heffer tries to sneak into a nightclub for elk by putting on a pair of fake antlers and telling the bouncer "I am an elk. I have antlers." The bouncer quips "You want a prize?" before letting him in.
* Whenever [[EarthwormJim Evil the Cat]] made an appearance that required him to wear a ''PaperThinDisguise'', he would always reassure whomever he needed reassuring that he wasn't a [[CatsAreMean cat]]... Since this was Earthworm Jim, it did, of course, always work.
* Subverted in an episode of ''OutOfJimmysHead.'' When Sonny unveils his Jimbotron, a robot double of the protagonist Jimmy, it looks like a sub-B-grade science fiction movie robot with an unconvincing wig and one of Jimmy's shirts, which barely fits it. Sonny also has it say things like "If I'm not Jimmy, why would I steal one of his shirts?" It spectacularly fails to fool anyone except Jimmy's [[BumblingDad idiot father]], and even ''he'' had to be [[BlindWithoutEm missing his contacts.]]
* In one episode of ''[[WesternAnimation/TeenageMutantNinjaTurtles1987 Teenage Mutant Ninja Turtles]]'' Splinter and Shredder's minds are accidentally swapped. Splinter manages to bluff his way through, after almost being found out when he doesn't sufficiently insult and belittle Shredder's two idiot minions Rock Steady and Be-Bop.
*''DannyPhantom'': Danny does this when overshadowing his father in "Parental Bonding".
* In ''TheSimpsons'', Bart barely convinces a group of children from Shelbyville that he is one of them. "No, not in my mouth! ...uh, is what that kid would say."
** To be fair they don't have a clue who he is even after his reveal.
---> It's me Bart Simpson ''Confused looks'' From Springfield
** Grandpa has also described times he hid out in NaziGermany disguised as a female cabaret dancer - one that Hitler found attractive until a "costume malfunction" revealed him to be a fake.
* ''InvaderZim'' invokes this trope by necessity in order to maintain his PaperThinDisguise ("I'm human! Yep, human, human, human. Just look at my neck!"). Only his nemesis Dib and Dib's sister Gaz ever notice. In the episode "Abducted" however, he encounters a pair of even ''stupider'' aliens who have even ''worse'' disguises and invoke the trope even ''harder''.
**Even funnier? These aliens abducted Zim ''because they actually thought he was a human!'' (And then abduct Dib because they think he's a weasel.)
* One episode of ''TheTick'' involves a shoddy green clone of Arthur who says nothing but "I Arthur". Naturally, the Tick can't tell them apart.
* An episode of ''Ben10AlienForce'' features an alien with a copied Omnitrix stuck in Ben's form. When he first attempts to pass himself off as the real Ben, he says stuff like "Yes, it is I, Ben Tennyson. Escort me, Ben 10, to my domicile."
* In ''TransformersAnimated'', when Wasp disguises himself as Bumblebee (and makes Bumblebee look like Wasp), his disguise is compromised by his penchant for talking in the third person, and his habit of calling Bumblebee 'Bumblebot'. The same happens to Bumblebee, except because of his lack of third-person speaking. Naturally, no-one notices.
* In ''Futurama'', the Brain Slugs are one-eyed, fist-sized slugs which attach to the heads of their victims. As if this weren't obvious enough, they speak of their host in the third person constantly. The trope is subverted by everyone matter-of-factly recognizing that the Brain Slugs are there (even Fry, but it takes him a bit), and thus humoring it while going off to do something else entirely.
* FamilyGuy; "Hello hebrews and shebrews, what a glorious Jewish day..." (doesn't work)

[[/folder]]

[[folder: Web Original ]]

* As mentioned above, Dr Alex Brisbane. He may lure the heroes into an obvious trap, but he's still definitely not a villain. Of course, as the people he has to fool are Joey, Tristan, Tea and Yugi not a one of them thinks there's anything strange about him.
** Well, ''Yugi'' does. Though his reaction is less "he's definitely a villain!" and more "I'm tired of rescuing people. Let's just go home and forget this happened." Unluckily, Brisbane easily tricks Tristan and Tea to [[SchmuckBait "step on the map"]], dragging Yugi along for the ride.
** "HOW DARE YOU DEFY ME!"
** Also, at one point, Evil Bakura tries to impersonate Normal Bakura. He mentions his "Britishness", says he had to do British things like "drink tea and eat [[strike:"crumpets"]] bangers and mash" -- and everyone falls for it.
*** Don't forget, he does those British things because he's British.
** And of course we have "Malik Blishtar" who is "definitely ''not'' Marik Ishtar".
*** "[[TheVentureBrothers IGNORE ME!]]"
* ''DrHorriblesSingAlongBlog'' invokes this a version of this trope when Penny introduces Captain Hammer to Billy at the laundromat.
--> ''Billy: We're meeting now for first time.''
** Also, it doesn't actually fool Hammer, who just waits until Penny's out of earshot to make it clear [[IKnowYouKnowIKnow he knows]].
* An episode of ReBootTheAbridgedSeries has this with Cyrus/Syrus/however his name is spelled.
* ''Metaleeto'' impersonating a criminal:
-->Rest assured, I love crime and also don't shower.

[[folder: Real Life ]]

* [[TruthInTelevision Tourists.]] Their "I ♥ NY" T-shirts give them away EVERY time.
** I just came back from NYC, and personally I would have thought it was that they were the only ones waiting for the pedestrian lights.
*** Wait, there is anybody who actually waits for the traffic lights in NY???
** Actually Lampshaded in {{CSINY}}. When they find a victim wearing such a shirt, they immediately assume it's a tourist. They are right (although he was actually wearing it because he spilt coffee down his shirt and was there to [[spoiler: rescue his daughter from a brothel]] rather than sightseeing). In a subversion, Danny mentions he wanted one as a kid (when he got one, it got him beaten up at school).
** If they DON'T wear "I ♥ NY" T-shirts, the accent will reveal the truth.
*** Yeah... Or, as ''TomLehrer'' so briliantly put it some 40 years ago:
---> '''Tom Lehrer''': ''If you take the various popular song forms to their logical extremes, you can arrive at almost anything from the ridiculous to the obscene, or -- [[YouSuck as they say in New York]] -- [[TakeThat sophisticated.'']]
* [[http://failblog.org/2009/07/22/telemarketing-fail/ This]] picture. Definitely, absolutely not a telemarketer.
* My Dad grew up in a country town (In Australia) and he tells me that he's NEVER heard anyone from the country yelling "Kooo-eee", only people from the city pretending they're from the country
** And while I'm on the subject, I have NEVER had shrimp or any crustacean at a BBQ, that's actually an American thing. We don't even call them shrimp. And the only places I know of where you can even GET hats with corks hanging from them is tourist places.
* Canadians do not wear Canadian flag pins or shirts when visiting other countries.
** Everyone in Britain just assumes a Canadian it an American with the sense not to admit it anyway.
* The increase in "staycations" (not a word I use) means that some Britons will act like this while they only in another part of Briton (even their own country). When ThisTroper was on a trip to London at the age of about 13 his grandmother chastised him for acting like an American tourist for considering annoying one of the palace guards (you know, the kind who aren't allowed to move [[spoiler: unless they want to give a particularly annoying tourist a slap]]).
