This trope is where a character states a relationship with someone else through a long and indirect chain of connections. The chain can be simple (I know this guy who knows this guy) to elaborate (My uncle's drinking buddy's doctor works with this guy whose brother's fiancee...). Sometimes, despite this, the person acts as if he or she knows the person really well. Other times, it's reversed; they really do know the person well, and are making up this long string of connections to socially or legally distance themselves from the other party.
Usually the elaborate case is used as an hope/promise for a plan, which very rarely delivers.
See also Screw the Rules, I Have Connections!, where this is not only true, but makes a character significantly powerful. Compare ...Or So I Heard for cases where the character is downplaying his connection with a disreputable associate. Not to be confused with I Know A Guy, which redirects to Friend in the Black Market.
- Doraemon plays with this. Taking advantage of the "Six Degrees Of Separation" theory via one of the usual Imported Alien Phlebotinum, Nobita is able to meet celebrities and other famous people at will. Apparently the device has a few bugs to work out given that amusing things can happen if the names of the people you want to meet are too similar.
- In The Tonsillitis Episode of Calvin and Hobbes: The Series, Socrates quotes the SpongeBob SquarePants example verbatim.
- Harry & the Mysterious Curse of the Girl Who Lived:

- Ninja Wizard Book 2:
Harry: My cousin Dudleys friend Piers uncles neighbor works at the police station in Surrey.
- Naruto in Myoushuu no Fuuin has a great deal of connections in the criminal underworld and always refers to this trope by name. It gets to the point that when Team 7 has to find Jiraiya (after already tracking down Tsunade), they jokingly express shock that Naruto doesn't "Know a guy who knows a guy who's secretly his traveling companion".
- From The Emperor's New Groove:
Chicha: So, remind me again how you're related to Pacha?Yzma: Why, I'm his third cousin's brother's wife's step-niece's great aunt. (beat) Twice removed.

- From Ferris Bueller's Day Off:
My best friend's sister's boyfriend's brother's girlfriend heard from this guy that knows this girl who's going with a guy that saw Ferris passed out at 31 flavors last night. I guess its pretty serious.
- From Hot Fuzz: "That's Auntie Jackie's sister's brother's boy". That he doesn't just say 'my cousin' suggests complicated relationships... or just Rule of Funny.
- From Sharpay's Fabulous Adventure:
"I texted Bridget, who e-mailed Constance, who tweeted Bethany, who IMed Jenn, who Facebooked Kara, who has an ex-friend who she caught with her boyfriend, who she then dumped, so now Karas her friend again, who knows of a New York apartment available in a luxury townhouse."
- From Jetsons: The Movie
Judy Jetson:"I just found out Doris told Susie and Susie told Mary and Mary told Francie and Francie told me Helen took my date with Cosmo!"
- Monsters, Inc.: Boo is Sully's cousin's sister's daughter. Why he didn't just say first cousin once removed is probably trying to invoke this for "Bring an Obscure Relative to Work Day".
- From Sexy Beast:
Don:"I know a bloke, who knows a bloke, who knows a bloke. Now you know this bloke."Gal:"Do I?"Don:"This is a bloke you know."
- In Conan the Destroyer, Conan's sidekick told the heroes that his "brother's sister's cousin" knew a secret entrance into the Big Bad's palace. (Exactly why his "brother's sister" wasn't also his sister is something he doesn't explain; fortunately, the secret entrance is there.)
- In Starsky & Hutch, Huggy Bear uses this to explain how he got his new Lincoln.
"It's a '76. Won't be out 'til next year. But I know some people that know some people that robbed some people."

- In Harry Potter and the Goblet of Fire, Ron, who is currently not on speaking terms with Harry, has Hermione relay the news to him that Hagrid wants to see him. This bit of news had apparently been relayed through several other people before reaching Ron, and Hermione frustratedly tries to list them all out. She gives up when Harry asks her to repeat the list. Later, Ron reveals that he actually heard the news directly from Hagrid and made up the rest of the chain.
- Ocean's Eleven. Danny uses this trope after The Caper comes off successfully to throw off suspicion. When Benedict demands to know if Danny is responsible, Danny says he knows a guy he did time with who knows anyone who could have pulled off such a heist. Benedict just thinks he's being played and hands him over to the police for parole violation.
- The Hitch Hikers Guide To The Galaxy:
- In Life, the Universe and Everything, Effrafax of Wug got rid of the mountain he was supposed to render invisible with the aid of "his friends, and his friends' friends, and his friends' friends' friends, and his friend's friends' friends' friends, and some rather less good friends of theirs who happened to own a major stellar trucking company".
- In So Long, and Thanks for All the Fish, Arthur mentions the Urban Legend version by saying the story he's about to tell sounds like one of those ones that happened to a friend of a friend of a friend but probably got made up somewhere along the chain, but this one did happen, because it happened to him. (It actually happened to Douglas Adams.)
- In Michael Connelly book The Gods of Guilt, Cisco says he knows "some people who know some people".
- In Mark Twain's "Two Little Tales" the second tale features an elaborate one of these which stretches from the son of a cesspool emptier to the emperor. The son's best friend, a chimney-sweep, comments on it:
It's a philosophy, you see. Mighty good word—and large. It goes on this idea: everybody in the world, little and big, has one special friend, a friend that he's glad to do favors to—not sour about it, but glad—glad clear to the marrow. And so, I don't care where you start, you can get at anybody's ear that you want to—I don't care how low you are, nor how high he is. And it's so simple: you've only to find the first friend, that is all; that ends your part of the work. He finds the next friend himself, and that one finds the third, and so on, friend after friend, link after link, like a chain; and you can go up it or down it, as high as you like or as low as you like.
- SyFy's Alice has:
Hatter: I know some people, who know some, well, other people.
- This is how Saul arranges a meeting between Walter White and Gus Fring in Breaking Bad. And its quite literal.

When the first attempted meeting falls through, Saul has no idea how to try again.
- From Cheers:
Sam: I know a guy who knows a guy...Diane: And he's a bookie?Sam: No, but he knows a guy who is.
- In Burn Notice, Sam's key role is being "the guy who knows a guy". The amount of contacts he has is absurd, even for a former Navy SEAL who's had quite a lot of meetings with other departments of the government in his time.
- This is the only explanation for where the martial artists of Power Rangers Jungle Fury got their hands on high tech morphers. Y'see, the substitute mentor knows a guy who knows a guy who has an uncle who's has a connection ...

- In "The Magnificent Ferengi", Quark speaks of doing "business with the nephew of the cousin of the stepsister of a friend of the secretary to the [Balcanar] Consortium's chief accountant."
- Garak seems to have an inexhastive supply of "Contacts on Cardassia" that he can call upon to assist the plot. This is usually played for humor, but the episode "In the Pale Moon Light" plays this serious as many of these contacts are people who, while vaguely described, make Sisko second guess the need for their service just by the morally high prices that those contacts ask. Inverted as well, as one contact thinks Sisko was nothing but a Dirty Old Man and jokes around about what Sisko wants him to do... that is, until Sisko tells the guy it was Garak who made the meeting possible, which horrifies the contact into better behaving himself.
- Subverted in That '70s Show when Eric and Kelso are buying promise rings for Donna and Jackie, and Kelso brings them to an alley.
Eric: Kelso, this doesn't look like a ring store.Kelso: Don't worry, I know a guy who knows a guy.[Leo walks into the alley]Leo: Hey, dudes.Eric: Wait, Leo's the guy? I thought you said you knew a guy who knew a guy.Kelso: Yeah, I do.Eric: I know Leo.Kelso: OK, so you're the guy.

- Tom Lehrer:
- "Lobachevsky", from Songs by Tom Lehrer, has an exaggeratedly long one of these:
I have a friend in Minsk,
Who has a friend in Pinsk,
Whose friend in Omsk
Has friend in Tomsk
With friend in Akmolinsk.
His friend in Alexandrovsk
Has friend in Petropavlovsk,
Whose friend somehow is solving now
The problem in Dnepropetrovsk.
- Then the next verse runs through the whole thing again backward, somehow adding two more towns into the "chain".
- His song "I got it from Agnes" is a series of chains.

Cause somebody's mama knows somebody's cousinand somebody's sister knows somebody's husbandand somebody's daughter knows somebody's brotherand around here we all look out for each other.
- Urban Legends are often purported to happen to such people. In fact, folklorists who study Urban Legends have the acronym "F.O.A.F." which stands for Friend Of A Friend. The fact that such legends are often proven false or at least never proven conclusively could be seen as a variant on the "promise that never delivers" part of the trope.
- Played with in Driver: San Francisco: One mission involves playing as two undercover cops to defuse a couple of truck bombs on the highway. Once the madman reveals he has around half a dozen more cruising the city, Tanner remarks the trope name. This is referencing Tanner's shifting ability to possess any driver on the road which he uses to locate and defuse the rest of the bombs.

- In Exterminatus Now, Eastwood knows a guy who knows a guy that can examine the artifact that a bunch of heavily armed mercenaries tried to steal from them. He forgot exactly which friend he knew this guy through, though...which bites him in the ass since said friend turns out to have been Silas Morth, who is behind the whole operation and is blackmailing the examiner into delivering the artifact to him.
