Bus Stop Guy is one of House's poker buddies in the Season 2 episode House vs. God. He was portrayed by actor David Cheaney.
When House has a four card possible straight flush on the table and raises, Bus Stop Guy thinks he's bluffing and calls. However, when Wilson quickly folds, the other two players do as well. Bus Stop Guy realizes that House has at least a straight, but House flips over his hole card showing he has hit the straight flush and has only caught one player.
