From Midnight Express;
Ahmet: Where are you going? Why don't you walk the wheel with us? What is the matter my American friend? What has upset you? Oh, a bad machine doesn't know that he's a bad machine. You still don't believe it? You still don't believe you're a bad machine?
Billy Hayes: Oh, I know. I already know. I know that you are a bad machine. And do you know how I know? Huh? I know, because I'm from the factory. I make the machines!
