->''"When a spy finds a listening device, the last thing he does is turn it off."''
-->-- '''Michael Westen (Narrator)''', ''Series/BurnNotice''

People notice their phone is tapped, or see a microphone in their potted plant, or otherwise discover that someone is spying on them. So they start acting.

A specific version of this is when two people being audio bugged carry on a conversation for the benefit of the bug while holding the ''real'' conversation by sign language or exchanging written notes. (And the visual conversation will often begin with a note or signal meaning "I should warn you we're being bugged".)

* Sasuke did this in ''Manga/{{Naruto}}'' by giving his teammates a long and complicated password that the real Naruto would never be able to remember. They get separated soon after, and when they next see Naruto, he gives the correct password, and Sasuke correctly assumes this Naruto is an impostor using Transformation Jutsu who had been eavesdropping earlier.
* Combined with BluffingTheMurderer in ''Manga/TheKindaichiCaseFiles'': On at least one occasion, Kindaichi stages a fight and pretends to go off alone in order to lure out the suspected killer.
* In an episode of ''Anime/GhostInTheShellStandAloneComplex'', the Major realizes that the Tachikomas are observing her meeting with Batou. She and Batou proceed to hold two conversations simultaneously: they speak audibly to mislead the Tachikomas, while using their neural implants to message each other wirelessly and say what they really mean.
* ''Manga/FullmetalAlchemist'': Hawkeye needs to get Mustang a message about [[spoiler:the identity of the homunculus Pride]], but knows that [[spoiler:Pride]] is observing her, so she signals Mustang by tapping her mug. They then have a long, apparent innocuous conversation that's a cover for a coded message.
** Actually, Roy does this for an undefined ammount of time, he's a well known ladies' man so he acts like he's talking to one of his girlfriends in his phone while in truth he is giving coded instructions to his underlings.
* Light did this with Kyomi Takada in ''Manga/DeathNote'': They were having one conversation for the benefit of the Task Force listening in, while secretly writing notes to each other containing the real conversation.
* Done rather humorously in an episode of ''Anime/SonicX'' with a bugged prison cell. Knuckles cottoned on and interrupted the conversation about the Chaos Emerald with one about food.
* Happens in ''Anime/GirlsUndPanzer'': Miho realizes the enemy is listening on their radio transmissions, so she begins giving false orders through the radio to lure the enemy tanks into ambushes while delivering her real instructions with her cell phone.
* ''Manga/MakenKi'': Takaki demonstrates [[TheSmartGuy why]] she's Tenbi's [[BigGood chief strategist]] by outwitting Jigoku, after Sui warns her of Jigoku's ability to detect sound across great distances. Then adds that even if they wrote their conversation down, he'd still be able to discern it based on the sound of their penstrokes. So Takaki [[BeatThemAtTheirOwnGame feeds Jigoku false information]] by using her right hand to write a phony mission brief, while using the index finger of her left hand to relay her real strategy in midair. Gen follows suit, leaving Jigoku none the wiser.
* Done for laughs in ''Manga/WildAdapter''. Kubota, having guessed that they're being spied on, finds a bug in their apartment, and when Tokito asks what he is looking for, shows it to him and asks if Tokito has seen his glasses (which Kubota is wearing). Tokito takes a second to realize what's going on, and replies that they're [[LastPlaceYouLook on top of Kubota's head]], playfully wondering if Kubota is growing old. The guys listening are then treated to an increasingly explicit dialogue that suggests the two [[HoYay are about to have sex]], and are promptly disgusted. Cut to the duo sitting on their sofa with completely deadpan expressions, improvising the conversation before Tokito breaks the device, letting the listeners know that they've been found out and messed with.[[note]]What makes it even more hilarious is that the panel that reveals Tokito and Kubota sitting on the sofa is at the top of its page, meaning that until that point even ''the reader'' can fall for their trick.[[/note]]

[[folder: {{Comic Books}}]]
* In ''Astonishing Comicbook/XMen'', ComicBook/{{Cyclops}} is aware that the enemy is probably listening to the team's conversation, so he signals Emma Frost to link the team telepathically. He then lays out his plan via the link, while the team has a verbal conversation designed to lure the enemy into a trap. It's particularly effective because the ''readers'' aren't aware of the second conversation until the scene is [[OnceMoreWithClarity revisited]] in the next issue.

[[folder: {{Fan Works}}]]
* In Creator/AAPessimal's ''{{Discworld}}''-set tale ''Gap year Adventures'', Assassins Horst Lensen and Mariella Smith-Rhodes are "administrative detention" by the local police in [[UsefulNotes/SouthAfrica Rimwards Howondaland]]. Horst, who has just been searched, loudly apologises to Mariella that all his weapons and equipment have been discovered and taken away. Aware Mariella has not been searched yet as the local police cannot find any qualified female personnel to conduct a search, they conduct a ''second'' conversation in Assassin sign-language and finger-code in which Horst suggests it would be a good idea if she slips him some of hers, so that ''one'' of them has some weapons available.

* ''Film/TheKentuckyFriedMovie'''s segment "A Fistful of Yen". While in Dr. Klahn's headquarters, Loo is about to discuss escape plans with Ada Gronick when she shows him a listening device. They make polite conversation as she shows him the rest of the devices and spies.
-->'''Ada Gronick:''' [speaking quietly] The guards will have to be bribed. We'll need money.
-->'''Loo:''' We can raise the money, that's no problem. [Reaches up and pulls down an overhead microphone, speaks into it] But that would be wrong.
* ''Film/TheAdventureOfSherlockHolmesSmarterBrother''. Franchise/SherlockHolmes and Watson are in a room when Holmes silently informs Watson that there's someone listening at the keyhole. They then have a conversation intended to fool the eavesdropper that they're leaving the country.

The rest of the team keeps talking while Stavros sneaks over to the door catching the eavesdropper and pulling him into the room. It's the first sign that things may not be going as planned.
** In a darker variant from the same film, Mallory feeds disinformation to the loyal but badly injured Franklin, knowing that when Franklin is captured the Germans will extract the disinformation and be decoyed.
* In ''Film/AfterTheSunset'', after the retired jewel thieves discover that the FBI agent has hidden a bug in their apartment, they begin talking like they're getting ready to have sex. (the fact that he's eagerly listening to all this is genuinely creepy). Then the woman claims to have invited another woman over to join them. . .the agent's mother. At this point, they bid him good night, then smash the bug, causing painful feedback in his ear.
* ''[[Series/{{Thunderbirds}} Thunderbird 6]]'': when Lady Penelope is talking with Alan about Skyship One's captain Foster, of whom they both already suspect that he is not who he claims to be, the lamp next to her bed falls of the table, revealing a listening device underneath. Realizing the ship's crew is eavesdropping on her, she quickly alters her opinion about Foster and tells Alan they shouldn't jump to conclusion so fast.
* A villainous example in ''Film/TheresSomethingAboutMary''.

This is also done in the American remake ''Film/TheManWithOneRedShoe''.
* In ''Film/EvidentDomain'', a Soviet official is suddenly taken off from his job and is put under surveillance. After learning that his home is bugged, he fakes a fight with his wife about a lover that he "wasn't supposed to see anymore" so that she'll have an excuse to leave town while he investigates the matter.

* Used in ''Literature/The39Clues'' series, more than once to throw the other Cahills of the track
* During the "David" arc in the ''Literature/{{Animorphs}}'' series, once the team realizes how unstable and dangerous David is, they sometimes do this while discussing their plans, in case he is eavesdropping on them in morph.
** They host a similar fake conversation when some Andalite assassins (claiming to be there solely to kill Visser Three) show up and the Animorphs are pretty sure that the assassins are not what they claim to be. The Animorphs pretend to break up when they strongly suspect Estrid and Arbat are listening in, allowing Ax to join with the assassins and figure out what their ''real'' plan is.
* In the ''Literature/{{Discworld}}'' books, Vetinari sends all his semaphore communiques using codes that are "fiendishly difficult" but not unbreakable. He wants people to read them so that [[IKnowYouKnowIKnow he knows what they think he thinks they're thinking]].
* In one of the ''Literature/{{Foreigner}}'' novels, protagonist Bren is in a situation where, to communicate with the alien ''atevi'', he must use the communications systems of a group of humans who are not only eavesdropping on him, but blocking the transmission of anything they don't like. To get around this he sends a message comparing his situation to a scenario in a particular genre of ''atevi'' popular culture, a comparison which seems innocuous to the human eavesdroppers but which clearly explains exactly how much trouble he's in to any ''atevi''.
* In Creator/JohnGrisham's ''Literature/TheRainmaker,'' Rudy Baylor discovers that the attorneys for the insurance company he's suing have tapped his phone. He considers exposing them, but he realizes he'll never prove they were the ones who did it. Instead, he leaves the tap in place and feeds them false information, making them look like fools in the courtroom and rigging the jury in his favor.
* Used in the third ''Literature/SammyKeyes'' book by Sammy and her friend Marissa, who are catcher and pitcher, respectively, of one of their school's softball teams. They're eating lunch before a big game when Sammy notices a member of the rival team lurking nearby, so she and Marissa start loudly going over what signals Marissa's going to use for each of her pitches--the ''wrong'' signals, of course.
* In ''{{Literature/Doom}}: Hell on Earth'', Fly and the squad meet some infiltrators posing as drug dealers and making zombie serum. The spies blast obnoxiously loud music and everybody talks about bands and drugs while holding the real discussion on notepads.
* Invoked in ''[[Franchise/ConanTheBarbarian Conan And The Manhunters]]''. Some priests pay a couple of guards to stand outside a prison window and discuss how the city's treasure is going to be stored in the basement of their new temple. Conan, a robber chief this round, is in that cell and manages to escape. [[spoiler:The priests needed magic present to begin the awakening, and there was no way Conan's band could move all the cash without a wizard's help.]] Complications ensue.
* In ''Literature/TheDresdenFiles'' book ''Cold Days'', Harry knows [[spoiler:Lara has placed bugs in Thomas' apartment]]. So when he calls up a contact, he speaks with a representative of the contact, warns them the line is bugged, and uses big words like "operative." Harry knows this will get her attention and send her to keep track of whomever Harry has contacted. [[spoiler:The bluff comes when Harry reveals he wants Lara to try and track Odin as he will spot them and this will tell him how the White Court does its surveillance now. This information is payment to him for agreeing to meet Harry at all]]. Harry then [[spoiler: blows out every electronic device in Thomas' apartment]], which really should have been a tip-off, but was awesome nonetheless.
** Taken UpToEleven and mildly [[DeconstructedTrope Deconstructed]] in ''Skin Game'' with [[spoiler: the possibility that Anduriel is listening and watching ''[[ParanoiaFuel at any time]]''. Harry has to do a book-long, solo version of this, which strains his interactions with his friends since he isn't telling them anything.]]
* The Literature/TommyAndTuppence book ''The Secret Adversary'' uses this with the character of Annette. [[spoiler: Annette is actually Jane Finn, pretending to have trauma-induced amnesia so she can't be forced to reveal the location of a set of secret documents. Part of her ruse is "forgetting" how to speak English and only using French; at one point, she realizes she's being spied on and starts crying and wailing in French so her kidnappers are convinced the amnesia is real.]]
* Creator/PennAndTeller's book ''Cruel Tricks For Dear Friends'' includes a sample letter to put on your laptop and pull up when a nosy neighbor reads over your shoulder. It makes it look like you're writing a letter about how you just got out of prison for killing someone who annoyed you by reading over your shoulder, and how you wouldn't hesitate to do it again.
* Taken to LogicalExtreme in "A Private Eye", short SF story, as it takes place in the future where ''your entire life'' is being constantly taped.

[[folder: Live-Action Television]]
* In ''Series/{{Farscape}}'', Crichton and Aeryn eventually do this to Scorpius, apparently getting him to believe that their relationship is at an end and Aeryn can't be used against Crichton. [[spoiler: "Apparently" being the operative word; Aeryn ends up getting kidnapped in an operation that Scorpius apparently had a hand in, so the whole gambit is rendered completely pointless because Crichton ends up offering Scorpius everything he wanted in return for Aeryn's safety.]]
* ''Series/BurnNotice'':
** Michael often bluffs people listening when he knows he is being bugged.
** Michael gets it used ''against'' him: in one episode when it's clear that his apartment is under surveillance, he tries to hold an innocuous conversation with Fiona, who instead uses the opportunity to force Michael to talk about their relationship (which is still innocuous, at least to the people listening).
* in ''Series/{{Chuck}}'', Chuck realizes in one episode that Casey is eavesdropping on him, so he begins talking about sandwiches with Morgan to annoy Casey.
* This was done in the season 3 finale of ''Series/TheMentalist'', to give one of the CBI employees who might be Red John's spies the room number of a person they were hiding. The person is actually somewhere else, and the room number is a trick to reveal who is Red John's spy.

They then let some false information slip out while talking and make noises that imply their hideout is under the watertower.
** In "Eight O'Clock and All is Well", a [[TheMole Mole]] uses the technique against them. As far as the Heroes, listening through a bug in Klink's office, are concerned, the new prisoner is playing Klink to get out of a punishment. Meanwhile the [=Mole=] has passed Klink a note identifying himself as Gestapo, and is pouring Klink a drink.
** In another episode, the Germans plant a bug in the prisoners' barracks. Hogan uses it to feed the Germans false information, with the prisoners reading parts off of scripts.
* ''Series/{{Seinfeld}}'': While in the diner waiting for a reporter who's going to do a story on Jerry, he and George notice a young woman eavesdropping on their conversation, so to mess with her they pretend to be gay for each other.

They try desparately to convince her that they're not gay -- NotThatTheresAnythingWrongWithThat.
* In one episode of ''Series/{{Scrubs}}'', Dr. Cox realizes that [[ButtMonkey Doug]] is listening to him and says to himself;

-->'''Dr. Cox:''' ... Now, if you leave, I'm going to know that you were listening to me [[MortonsFork and I'm gonna go ahead and kill you anyway!]]
* In one episode of ''Series/SueThomasFBEye'', the characters play football. The other team hides their mouths during huddles so Sue, who is deaf, cannot read their lips. On the final play, they let her see their lips, but call a fake play. She doesn't fall for the bluff.

* In the climax of the ''Series/StarTrekTheOriginalSeries'' episode "The Deadly Years", due to having been rapidly aged by mysterious radiation and gone senile Kirk has stepped down from command and his incompetent replacement has led the ship through the Romulan Neutral Zone and the latter are about to destroy them. Suddenly a cure is found, a restored Kirk appears on the bridge and gives an order to relay a message to Starfleet... using a code previously established as having been broken by the Romulans, which briefly causes the crew to wonder if he's still senile. Nevertheless, they open the channels and Kirk sends a message that the ''Enterprise'' will self destruct via the [[CallBack Corbomite Device]] and destroy any ship in a huge radius. The Romulans intercept the message and leave.

It gets the case thrown out of court.
* A ''Magazine/{{MAD}}'' strip suggested several ways to mess with them (for the kind of eavesdroppers who are just nosy folks, not spies). Like on an airplane: "That nice Arab guy gave me this package for his grandma. I bet it's a clock - you hear how it's ticking?"

* Used in ''Theatre/MuchAdoAboutNothing'' to make Beatrice and Benedick fall in love with each other.

* In ''VideoGame/MetalGearSolid'', Liquid and Ocelot discuss their PAL codes and Snake's card key deactivating Metal Gear Rex, knowing that Snake is spying on them, to further fool Snake into unwillingly doing their bidding for them.

* ''Webcomic/{{XKCD}}'' [[http://xkcd.com/525/ #525]]:

* In ''Webcomic/QuestionableContent'', Faye, Dora and Marten against the Vespavenger, starting [[http://questionablecontent.net/view.php?comic=739 here]].
* Subverted in ''Webcomic/TheLastDaysOfFoxHound'' when Gurlukovitch calls Ocelot on a cell phone to discuss their evil plan. Rather than bluff the people he knows are listening in, Ocelot ''flat out scolds Gurlukovitch by telling him exactly who is listening in on the other end''. Cue said eavesdroppers [[CrowningMomentOfFunny breaking silence to wonder how Ocelot does it while Ocelot rolls his eyes and Gurlukovitch listens in disbelief.]]
* In ''Webcomic/GirlGenius'' Zola plays up her false ditsy blonde persona and acts like her plans are much less complex and dangerous while walking in the parts of Castle Heterodyne that can listen in to her conversation with Gil. As soon as she's in a "dead zone" she drops part of the act and explains that she's got a device to kill the castle.

[[folder: WesternAnimation]]
* From ''WesternAnimation/AvatarTheLastAirbender'': a masterful example by [[TheDragon Azula]], when she has [[SugarAndIcePersonality Mai]] and [[PerkyFemaleMinion Ty Lee]] purposely reveal that they're Fire Nation in disguise... to the pair of Dai Li agents they knew were eavesdropping, overhead. She knew they'd ferry the news back to [[EvilChancellor Long Feng]], and knew he couldn't resist the opportunity to use it against her. So she wasn't surprised when those same agents brought her to his cell, where he coerces her into helping him under threat of exposing her to the Earth King. [[MagnificentBastard Azula]] "[[ObfuscatingStupidity reluctantly]]" agrees. It doesn't end well for Long Feng.
* In one episode of ''[[WesternAnimation/AdventuresOfTheGummiBears Gummi Bears]]'', the king tries to find out a famous chef's secret recipe by listening at the door, which the chef thwarts by reciting absolute nonsense instead of his ingredients.

* One episode of ''WesternAnimation/KingOfTheHill'' centers around Dale attempting to sue the Manitoba Tobacco Company for "ruining Nancy's skin" with their cigarette smoke, [[ItMakesSenseInContext so he can use the money to get her some plastic surgery]]. They send him a singing placard fish that's bugged, in order to get proof against Dale's claim. Being the paranoid nut he is, Dale almost immediately recognizes the bug, and decides to counter-bluff them. Unfortunately, he does this in some of the saddest and most painful scenes in the series by acting as a total {{Jerkass}} towards her.
* In one episode of ''WesternAnimation/AmericanDad'', Stan decides to stage a "disappearance" to see how quickly Francine would move on without him. When he gets back, he discovers that Francine had intentionally moved on as quickly as was plausible to get to him, remarking that it was suspicious that the house was full of {{Incredibly Obvious Bug}}s.

[[folder: RealLife]]
* The Finnish military bought equipment from the Soviet Union during the Cold War. Finns knew that their hotel rooms would be obviously bugged so while discussing in "private" they would mention X as absolutely definitely maximum agreeable price for a given item and like clockwork the next day Soviet negotiators would ask X+Y which would then be haggled to X.

* In the United States, it's a common practice among middle and highschoolers to post misleading updates about fake parties about to happen or are currently happening in order to intentionally mislead police tracking said facebook or twitter posts in the opposite direction of a real party, or just in a random direction for laughs; it's come to be called "Pied Pipering", at least in southern states. It's also common to "weaponize" police by posting fake concerns of nonexistent suspicious activity on fake accounts to send police or other authority figures to spy on the houses of people the poster doesn't like, in the same vein as "Swatting".
