Yes, I can say that it's very annoying when third person joins to chess..

To first guy: "No, don't move your queen there, he's got a knight guarding that spot!"

Second guy: (if looks could kill)

JUST KIDDING, I capture your pawn using en passant.

Doing that is fun, because not many people know of that move. Most people think, "Hey, did you just make up your own rule? That was ghey!!"
