Roz: What brings you here?
Frasier: Well, I'm just showing Dad around, then he's gonna sit and listen to the show.
Martin: Yeah, it's kinda like payback for when Frasier and Niles were kids. I used to take them to the police station and show them where I worked.
Frasier: Yes. He used to make a big game of locking us in one of the cells and then pretending to lose the key.
Martin: I was just joking with them, I knew they weren't scared.
Frasier: Well, no. We weren't really scared, although after a while we did become quite hungry.
