Niles: Frasier, who was that woman on your show today?
Frasier: Oh, that was Mary Thomas. She's filling in for Roz this week.
Martin: It seemed to me like she was filling for you.
Niles: You're normally so particular about what happens on your show. I'm surprised you let her go on like that.
Frasier: Well, I started to say something and then I thought, well, it might be a bit condescending.
Martin: I know why you didn't say anything. Cause she's black, isn't it?
Frasier: Oh, that's ridiculous, Dad. Race has nothing to do with it.
Niles: Oh, come now, Frasier. You can't deny a certain measure of guilt, living as you do in your exclusive lily-white world.
Frasier: Niles, owning the CD of "Ella sings Gershwin" does not qualify you as a soul brother.
