Drinks at Glunz, a German beer place.

Bringing the bill to our table, the jovial bartender (and I suspect, also the owner) said, "Any of you know how to say one in German?"

Me: Uh.. eins, zwei... Eins? Right?
Bartender: [pointing at leg] And how do you say this is German.
Me: I don't know.
Bartender: The leg is...?
Martin: Bein?
Bartender: So... put it together.... Ein...
Martin: Ein Bein?
Bartender: You're bine? Alright. [hands bill to Martin]

Ein Bein. Sort of sounds like "I'm buyin'." Must be a classic German American bartender joke.

Meador: Well, Martin, he got you.
