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, where the character is downplaying potentially embarrassing knowledge by claiming to have it secondhand rather than via direct experience. 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.

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 supposedly 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".

- At the climax of Ocean's Eleven, Terry Benedict assumes that Danny Ocean is responsible for the heist that just robbed Terry's casino.

So, when Terry presses him, Danny claims that he met a guy in prison who has information on every job pulled in the western United States, and Danny can use his connections to get him to give up the perpetrators.

- 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:

Sam: I know a guy who knows a guy...Diane: And he's a bookie?Sam: No, but he knows a guy who is.

- 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.

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.

- In episode four, she knows a guy who knows a cop who's willing to run a license plate for her.
- Played with in Driver: San Francisco: One mission involves playing as two undercover cops to defuse a couple of truck bombs on the highway.
