Quote from Frasier in Goodnight, Seattle
Frasier: Because it's not a word. Charlotte: Yes, it is. Frasier: No, it's not. Charlotte: Yes, it is. Frasier: Use it in a sentence. Charlotte: "Her grandmother's bed was warm and... quilty." Frasier: And why is she lying there? Because she's feeling all "befevered" again? Charlotte: Could I borrow your "F"? I've got a little message for you.
