Quote from Martin in An Affair to Forget
Frasier: Dad! Dad! I have to talk to you about Niles. I got a call on the show today from a German woman whose husband is a fencing instructor that she suspects is having an affair with his wealthy new client. Martin: And? Frasier: Don't you find that the least bit incriminating? Martin: No, I find it a coincidence. Seattle's a big city, I'm sure there's a bunch of German fencing instructors, each one with dozens of students. Frasier: Yes, but are they wealthy students? Martin: No. They're inner-city kids trying to work their way out of the ghetto with nothing but a foil and a dream.
