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.
