Niles: Oh, dear. The sound of that rain's going to keep me up all night.
Frasier: I'm amazed you can hear it over there in mission control.
Niles: Do you mind if I close the window?
Frasier: Not at all.
Niles: Ah, much better. [Niles turns on a tape]
Frasier: Niles, what are you talking about? That's just more rain noise.
Niles: No, it's much more than rain. This is all the sounds of the Brazilian rain forest. Does it bother you?
Frasier: No. Go to bed.
[A bird's screeching is heard on the tape]
Frasier: Oh, for God's sake, Niles!
