Quote from David in Livin' the Dream
David: Sensei, do you generally do house calls like this? Sensei: Uh, you can just call me Billy. And no. No, but Dwight insisted. He wanted to receive his black belt in the place he loves most in the world. David: He said that? He's an odd guy, isn't he? Sensei: Yes. Irritating, also yes. But I gotta hand it to him, he's one of the most tenacious and determined men I've ever met.
