I don't have eyes in the back of my head, I can't hear a flea walking, I am not in any way superman. But there's this... Voice in the back of my head that just keeps reminding me I might not be around long enough to do any of it. And the fact that you could do that again sits in the back of my head somewhere. If you're going to put a bullet in the back of my head, just do it. The... the way these people work... if I don't close the deal, they'll put a bullet in the back of my head, and they'll find another guy to do it.
