Marshall: Who's the second message from?
Lily: Dr. Stangel's office. I'm extremely fertile.
Marshall: You're extremely fertile! Oh, my God. I told you there was nothing to worry about. I got to call my dad and tell him the good news.
[Marshall grabs the phone. In Minnesota, his father listens to a football game while doing repair work in the garage. Marshall doesn't phone]
Marshall: If you're fertile, um, then that means I'm the problem.
