Doctor: Is there anything you would like to tell me before we start?
Harry: Yes, I am going to kill you very soon.
Doctor: Oh, how?
Harry: First I am going to use you as a human shield, and then I am going to kill that guard over there with that screwdriver... And then I was thinking about breaking your neck.
Doctor: I see, and what makes you think you can do all that?
Harry: You know my handcuffs?
Harry: I picked them.
