Quote from Frasier in The Improbable Dream (Part 1)
Lilith: What about Russell and Pam? Frasier: Oh, hang Russell and Pam. They just want to weasel some free psychological advice out of us anyway. So, Rebecca, go on about your dreams. Rebecca: I guess you could say the main problem is that this guy who's... I don't know, I guess you could say he's starring in these dreams... Is somebody I definitely should not be dreaming about. Frasier: Ah... Because even though he's a sexy and successful doctor, he's also happily married and about to be a father. Yes. There is no fruit so sweet as that which is forbidden. Lilith: Frasier, stop before you embarrass yourself further. Frasier: What? Lilith: Darling, you're the love of my life, but even I don't have erotic dreams about you.
