Roz: Of course, it doesn't help that I didn't get any sleep last night.
Frasier: Dating a snorer?
Roz: You know, Frasier, I'm getting just a little tired of your constant insinuation that I sleep around. I didn't get any sleep because of that idiot Chopper Dave. When he gets bored doing traffic reports he likes to buzz people's apartments in his helicopter.
Frasier: Oh, I can see how that would be annoying.
Roz: Well, it didn't bother me much, but the guy I was with is a Vietnam vet and he started having flashbacks.
