[flashback to Martin's later days on the police force:]
Frank: You going to carry that fish around all day?
Martin: Hey, he has a name. That's Eddie.
Frank: Why don't you get yourself a real pet? You know, like a- like a dog?
Martin: Ah, I'm not really a dog person. I just wanted someone in the family I could get along with. Did I tell you Frasier's not coming home for Thanksgiving?
Frank: Yeah, you did.
Martin: And have I told you about my weekly Sunday brunch with Niles and Maris?
Frank: Yeah, you have.
Martin: Well, I'd rather be at church. I'd get more to eat.
