Quote from Roz in Hooping Cranes
Roz: That's very funny. You know, I hope it goes well, because he doesn't speak any English, and the only French I know is "oui" and "non." Frasier: I suppose you'll just be using one of those. Roz: Before you get too clever, you're the one who's going out with his brother. Frasier: Have a nice date, Roz.
