Frasier: Niles and Roz? It's just ridiculous.
Martin: Oh, not this again.
Frasier: Well, they are just completely incompatible.
Martin: Well, haven't you ever heard about "opposites attracting"? I mean, look at your mother and me. We went together for six months, nobody thought it would last, we had forty happy years together.
Frasier: Never thought of it that way.
Martin: Yeah. And then, there are those relationships where people have a ton of things in common and of course they always work out real well. [laughs]
Frasier: Thank you, Dad, I suppose that was a backhanded comment about me and Lilith.
Martin: Wouldn't it be great if she was flying by here on her broomstick right now?

Roz: Why don't you just admit it? You're just doing this because you want Daphne.
Niles: Yes! Yes! Yes, I want Daphne. I think we belong together. Just like I think you and Donny belong together. And why should two people be happy when four people can be ecstatic?

Niles: Oh, in a funny way this reminds me of that wonderful moment in "A Streetcar Named Desire" when the brutish Stanley says to the ultra-refined Blanche, "We've had this date with each other from the beginning."
Roz: Well, I don't know the play all that well, but I can tell you right now I'm not all that refined.
Niles: No, actually I was picturing you more as Stanley.
