Quote from Roz in The Fight Before Christmas
Roz: What is it? Daphne: The other day I found out something about Dr. Crane I wasn't supposed to know. Roz: Frasier? Daphne: No, his brother. Apparently, he's had a crush on me for years. Roz: [sighing] Thank God! Daphne: What do you mean, "Thank God?" Roz: I've been afraid for months I'd be the one to blow the secret. Daphne: You mean you knew? Roz: Well, everybody kinda did.
