Quote from Niles in The Club
Frasier: After last night's behavior, I believe an apology is in order. Niles: I agree. Well? Frasier: "Well," what? Niles: It's your turn. I apologized first last time. Frasier: No, you didn't! Niles: I did so! I distinctly remember. It was after that shouting match at the Monet exhibit. I had my secretary leave a heartfelt apology with your service. Frasier: So you did. That means it is my turn again. Damn! ... I'm sorry. Niles: Me, too.
