Carla: So, uh, how was your night off? Bet you spend a lot of time worrying about that kid of yours.
Frasier: No, not a bit. We had a wonderful time. We knew he was in good hands, so we just sat back and relaxed. We had a much needed, healthy night away from him.
Carla: That's terrific. Oh, by the way, your sitter called and she said that Frederick rolled over by himself for the first time.
Frasier: What?! And we missed it? We must be the worst parents in the world.
Lilith: Frasier, let's rush home, fall to our knees and beg his forgiveness.
Frasier: I'll never get over this until the day I die! [both run out]
Carla: New parents, they're always suckers for that gag.
