Rebecca: Oh, Frasier, I'm sorry. I must have fallen asleep. What time is it?
Frasier: Well, it's pretty late. Uh, I guess I'll go downstairs and, uh, sleep on the couch.
Rebecca: Maybe I should just go.
Frasier: No, no, you don't have to go home.
Rebecca: You don't have to sleep on the couch.
Frasier: Just a second. [door opens, shuts]
Rebecca: Frasier, what was that?
Frasier: [o.s.] What was what?
Rebecca: I thought I heard a door slam. You don't think those guys are back, do you?
Frasier: No, no impossible. I locked and dead bolted it. They'd need a key to get in. Now where were we? Let's make this a night we'll never forget. [door opens]
Lilith: Frasier?
Frasier: Lilith!
Lilith: Rebecca?!
Rebecca: Lilith. Am I the only one who feels awkward here?
