Chandler: You know what just occurred to me? This could be our last  Thanksgiving just the two of us. I mean, we could be getting a baby  soon!

Chandler: Somebody is gonna pick us.

Monica: Yeah, but we haven’t heard a thing from the adoption agency and it has been weeks!

Monica: Name one of his books.

Chandler: (after a long pause) “The Firm”?
