Niles: [on the phone] Maris, I'm afraid I'll be delayed a few hours. Frasier and I have taken it upon ourselves to tackle a home repair. Yes, I'm working with my hands. Yes, I've worked up a bit of a sweat. I suppose I could take my shirt off.
Frasier: Niles, what are you doing?
Niles: She seems to be getting aroused at my attempt at manual labor. [on phone] Maris, I'm holding some sort of wrench.
Frasier: [taking the phone] Give me that! [on phone] Hello, Maris? Maris, Niles is busy now. No, never mind what I'm wearing.
