Jill: There is no possibility. You had a vasectomy.
Tim: They can be reversed. Or better yet, what if we had sex every day? If we had sex every day, then maybe one of my little guys who's been hiding is ready to make his move.
Jill: Tim, you obviously haven't thought this through.
Tim: I want us to think it through. You and me.
Jill: OK. OK, we will. All right. Suppose one of these guys-
Tim: Let's call him, uh, "Bob."
Jill: What is gonna guarantee that "Bob" is gonna get us a girl?
Tim: Bob won't let us down.
Jill: Bob let us down three times!
Tim: That wasn't Bob. That was Steve.
