Roz: Sorry I'm late, but I had a date.
Frasier: Yes, I thought that was last night.
Roz: It was a good date. How's your new girlfriend?
Frasier: I allowed her to climb to the first base camp on Mount Crane and I believe she's feeling the effects of the altitude.
Roz: Is one of them nausea? Cause I'm getting that right now.
Frasier: Oh, shut up!
