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?

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.

Frasier: Oh God, you haven't even heard the worst yet, Niles. The butcher shop was closed, so here I am with all my spices, everything I need to make my duck a l'orange, all I've got's the l'orange!
