Marshall: Look, I don't wanna be exactly like my family, and don't take this the wrong way, but I don't wanna be exactly like your family either. We'll be our own family, and we'll find our own way to freak out the people our kids bring home.
Lily: Great, now I'm crying. Look, we may have some really big decisions to make in about 10 seconds but right now, I don't care where our kids grow up as long as they have you for a father. Gosh, I hope you're the father. Just a little joke to lighten up the mood.
Marshall: What does it say?
Lily: I'm afraid to look.
Pete: [o.s.] It's negative.
Lily: Thank God.
