Martin: Look, the last thing I want on my birthday weekend is some big long drawn-out argument between you two, all right? Now let's just chill this beer that we brought, all right, and just put all these weird thoughts out of our minds.
Niles: Fine.
[Frasier and Mia pass through the living room]
Frasier: Oh, sorry, Dad. Come on, hon. Let's go see if our room still has that big creaky old pine bed that Mom and Dad used to sleep in. [o.s.] A-ha. Yeah, there she is.
Martin: [to Niles] Well, a guess a warm one wouldn't kill us.
