There were names, and lines connecting the names to other names, and some of the lines were in different colors and...
"Tell me," said General Granger, "is there anyone in my army who
isn’t a spy?"
Somebody disguises themselves
as a member of some group to sneak among them
. However, it turns out everyone else in the area is also in disguise. Primarily used in comedy.
A favorite scene is to have the primary detectives bust an operation, only to find out that the people they're busting are cops themselves. Depending on how much hilarity the writers are going for, there may be as many as three or four squads in the room at the time.
Once the multiple operations are revealed, Jurisdiction Friction
tends to ensue, with the squads arguing about who takes point, who can stick around, and who has to leave.
If they turn out to have been on the same side too, then it is Right Hand Versus Left Hand
. Sometimes the result of a Gambit Pileup
. Might also drive a character to demand: "Okay, will the real [X] please stand up?" - and then everybody
Compare/contrast I Am Spartacus
Due to the nature of this trope, spoilers abound.

Live Action TV
- Tom Lehrer introduced his song "The Wild West is Where I Want to Be" by saying, "A few years ago I worked for a while at the Los Alamos scientific laboratory in New Mexico.

- The Industrial Workers of the World (Wobblies), introduced in the supplement Acute Paranoia (1986). When Friend Computer heard about this secret society, it sent Troubleshooters to infiltrate it and report back to Internal Security; however, since the Real Life Wobblies fell apart before Alpha Complex was created, they were executed for failing to find it. After several iterations, one clever team created the Wobblies so they'd have something to "infiltrate". At first, every single member was an IntSec spy, but later they started finding "real" members of the society... who were actually spies from other secret societies.
- In Prototype, the game devolves into a three-way war between the infected, Blackwatch, and the player character, Alex Mercer.

The only people who are as innocent as they claim are K and Quark, given that Alice probably knows everything Clover does.
- This article from The Onion (which parodies the rumor that most of the members of the Ku Klux Klan being mostly run by undercover policemen). Conversely, they also once made a reference to a child porn site being busted by authorities, and every single visitor to the site claimed to be a concerned citizen trying to infiltrate the site and bring it down from the inside.

- Another episode had Lisa pretend to be part Native American.

- Similarly, Spongebob once tried to disguise as Mister Krabs when he molted his shell so he wouldn't look like a sissy in front of his old buddies; once Mister Krabs makes his confession, the others all reveal that they, too, had something to hide.
- In an episode of The Adventures of Jimmy Neutron, a picnic is accompanied by a series of parent-child games. Jimmy, who naturally despairs of Hugh winning anything unassisted, invents something that more or less instills hypercompetence in athletics. When Cindy wins after the device malfunctions, it's revealed that her "mother" is actually her bodybuilding aunt, which would mean the prize goes to the Neutrons - except that they fess up to cheating as well, at which point the presenter runs through every team present until near-terminally unathletic Carl and his father are revealed to be the only ones who haven't cheated in at least one of the events.
- Played for Drama in Batman Beyond - Terry attempts to stop an illegal weapons sale, but it turns out the 'dealers' were actually Gotham PD.

"It took us two months to set up that sting, and two minutes for you to ruin it!"
- On Invader Zim, Zim and GIR were once captured by even stupider aliens who thought they were an actual human and dog. These aliens' disguises were even more pathetic, such as human masks that they held to their faces with sticks.
- Teen Titans has a Playing with a Trope example. After finding not one but two undercover heroes, Brother Blood suspects this of the H.I.V.E Academy. "Was anyone in my school actually there to LEARN?" They were the only moles at the time but another student has a Heel-Face Turn later on.
- In the Wander over Yonder episode "The Bad Guy", Doomstone appears to be a Wretched Hive, but all of its inhabitants are merely pretending to be cutthroats and badasses - because they assume everyone else is the genuine article.
- Futurama featured an episode of robot soap opera All My Circuits, wherein a "Previously On..." segment featured several clips of characters claiming they had amnesia.

- Conservapedia. Trying to separate the trolls from the genuine maniacs is a Mind Screw of a task, not helped by the fact that people are judged there mostly by how much they suck up to the site's Small Name, Big Ego founder. One time, the wiki's creator decided to purge a large amount of the accounts. It's been said that he banned all the legitimate users, but kept the trolls. This overlaps with Poe's Law.
- The Something Awful presence on the conservative "alternative to facebook", The Tea Party Community, is a particularly wonderful example of this - at this point it's not clear how many normal users of the site there even are anymore, mixed in with all the Something Awful trolls, trolls pretending to not be trolls, people trolling them intentionally... and trolls from other places, who don't necessarily realize it's been taken over by SA.
- Tales abound of Agent Provocateurs infiltrating student political societies in the US only to find that the most radical elements are agents from a different source and all the actual students are perfectly reasonable and unobjectionable people.
- Supposedly when the Allies got hold of Nazi records at the end of World War II, they learned that every German spy in Britain had been found and turned into a double agent by Allied intelligence. In fact, "Double Cross System" found and turned every German agent in Britain. By 1941, the MI-5 actively ran and controlled the German espionage system in the United Kingdom. It got to the point that MI-5 had to actually jail some of their turned spies rather than letting them report back false information. If it seemed that nobody had gotten caught, the Nazis would've found that suspicious.
- It is said that the only reason the Ku Klux Klan is still around is the undercover police agents — they're the only members who reliably show up for meetings and pay their dues on time.
- The German extreme right-wing party NPD (Nationaldemokratische Partei Deutschlands, National-democratic Party of Germany) is infiltrated heavily by the Verfassungsschutz (Protectors of the Constitution, Germany's domestic intelligence agency). When talking about disbanding the party, the highest court ruled that with so many protectors in the party - which would all be exempt from prosecution - any abolishment trial would be doomed to fail. In fact, it seems that many of these planted moles are using their immunity and the paycheck from the Verfassungsschutz to actually help the party to survive. In one case, a high member of the NPD stated openly that without being paid from the Verfassungsschutz, he wouldn't have been able to build up the party's branch in his state.
- In the former East Germany, the Stasi made generous use of informers in the population to spy on antigovernment forces. So many, in fact, that the BBC reported that as many as one in seven East Germans were on the Stasi's payroll.

- Reportedly Anne Bonny, a pirate famous for disguising herself as a man, once became attracted to another pirate on her crew. She revealed her secret to the pirate and tried to flirt with him at which point she was shocked to discover that said pirate was Mary Read, another pirate famous for being a woman disguised as a man. This was rather awkward to say the least.
