A favorite trick of the PhantomThief, ImpossibleThief or an illusionist.

While talking to someone, this character will suddenly produce a small item. The other party slowly realizes that it's something ''they'' were carrying in their pocket just a moment ago, and quickly checks... but of course it's not there -- the thief has stolen it, unnoticed by the victim (and the audience). In a variant, the thief will tell the victim to "check your wallet", or ask "what's the time on your watch?" etc. Only when the victim discovers he's been robbed, the thief demonstrates the item and laughs.

The key here is that the victim doesn't even realize he's been robbed until the thief himself alerts him to this fact.

Usually, the thief returns the items to its owner afterwards.

* There's an episode of ''Series/{{Bones}}'' which involves the investigation of a bunch of street performers. One interviewee does this several times throughout the conversation, much to Bones' amusement and Booth's annoyance.
* In an episode of ''Series/DoctorWho'', Romana steals the Fourth Doctor's Jelly Babies off-screen. When he asks where she got them, she replies "The same place you do. Your pocket."
* {{Subverted}} in an episode of ''Series/{{JAG}}''. Harm is talking to a guy who specializes in clandestine operations, and at some point, the guy holds up Harm's wallet, criticizing him for letting the guy steal it, pointing out that he could use the ID contained within to allow him access onto the base. Harm then tells him to [[GenreSavvy open the wallet]], revealing that the ID card holder inside contains only a note saying "Arrest Me".
* Parker from ''Series/{{Leverage}}'' does this a lot; particularly notable is "The Twelve-Step Job", where she goes undercover in a rehab center, is prescribed antidepressants, and starts doing it ''unconsciously''. It's also how she met her master-thief mentor when she was 12.

* David Blaine, a street magician, does this by distracting the audience with a routine card trick, then drawing attention to their missing watch.
* Apollo Robbins sometimes takes this UpToEleven, not just stealing audience members' wristwatches, but also their wedding rings, cellphones, and wallets. Sometimes even the things inside the wallets, like driver's licenses and money. He always gives these back though, but not always in ways you'd expect (the previously mentioned wedding ring belonged to a woman, and was found in her husband's pants pocket, attached to his keyring).

* One group known as the "Bling Ring" stole from Orlando Bloom many multiple items. When they were caught, one of the members had their mugshot taken while he was wearing Orlando Bloom's black and white T-shirt. Bloom's reaction was sort of this...
