Roz: I thought your father was in charge of Christmas decorations.
Frasier: Oh, no, no, not this year. We're doing it my way. That's why I'm ordering a tasteful tree here. They'll even deliver it on Christmas Eve, fully decorated.
Roz: Gee, that'll be fun for Freddie.
Frasier: Oh no, Frederick won't be joining me this year. He's spending his vacation on an archaeological tour with Lilith.
Roz: He's spending Christmas with dried-up old bones?
Frasier: [laughs] I thought I told you, she's taking him on an archaeological tour.
