Ted: Well, Barney and his brother aren't exactly alike.
Lily: James is gay.
Robin: Really? I mean, never in a million years would I picture you with a gay brother, that's awesome.
Ted: Yeah. I just wanted you to have a heads up, so you don't act all surprised when he gets here.
[After a knock, Barney opens the front door]
Barney: Here he is.
James: What up, New York.
Robin: [to Ted] Thanks for the heads up.
