Quote from Roz in The Wizard and Roz
Dr. Tewksbury: Well, what was that all about? Roz: Well, she thinks she's psychic, but he doesn't believe her. Dr. Tewksbury: Well, no matter who's right or wrong, Niles needs to set up stricter boundaries with his patients. I learned that from years of practice. Roz: No, no. She's not his patient, she's his girlfriend. Dr. Tewksbury: Oh, well in that case, no matter who's right or wrong, he's wrong. I learned that from years of marriage.
