Frasier: Oh, Dad. You care for a coffee?
Martin: Nah. I can see where you might think I would, though. A guy walks into a coffee bar, he can't blame people for thinking he likes coffee.
Frasier: Yes, Dad.
Martin: Course, uh, if he didn't like it, he could make that clear to people. He might say, "I am not a coffee drinker" or "I have never tried coffee even once."
Frasier: Yes, all right, Dad.
Martin: "I am not even curious about..."
Frasier: Yes, all right!
