documents: #Person1#: Hey, stop. [What?] And give me your money.
  #Person2#: What? No, no. Listen here.
  #Person1#: No, you listen. Hand over your purse, and I won't hurt you.
  #Person2#: You've got to be joking.
  #Person1#: Do I look like I'm joking?
  #Person2#: Heh. Look. I only have two dollars in change.
  #Person1#: I don't care. Give it to me! And your phone and credit cards.
  #Person2#: Okay. Listen. Obviously, you haven't thought this through. I mean, who's going to rob someone as they walk out of a karate studio? Really?
  #Person1#: Right. You don't fool me. Anyone can get a black belt online in 10 minutes. And I have a knife.
  #Person2#: Listen, mister. I'm telling you to back off. I'm a fifth-degree black belt, and I've trained for 25 years. I don't want to hurt you, but I'll defend myself if I have to.
  #Person1#: Alright, baby. Let me have it.
  #Person2#: You'd better call 911 first.
  #Person1#: Right. [Punches and kicks and yells and screams ... ] Ahh, oh, man. Ooohhhh. That hurts.
  #Person2#: Yeah. Listen. Here's your two dollars. You'll need them to cover your medical bills.
