HORATIO: Hamlet.
HAMLET: What?
HORATIO: You're Hamlet.
HAMLET: Rats! I always mess that up. Hamlet. Hamlet. What did I say?
HORATIO: You said Macbeth. "Or my name isn't Macbeth."
HAMLET: Well, it isn't, is it?
HORATIO: Exactly. So you should be saying "or my name isn't Hamlet," since your name isn't Macbeth, it's Hamlet.
HAMLET: Let me get this straight -- since my name is Hamlet, I'm supposed to say "my name isn't Hamlet".
HORATIO: Precisely.
HAMLET: And I don't want to say "my name isn't Macbeth," since in point of fact my name isn't Macbeth.
HORATIO: Yes.
HAMLET: Are you sure about that?
HORATIO: Positive.
HAMLET: I always get confused by this "or my name isn't" stuff. Do I really have to say that?
SHAKESPEARE: All right, all right, I'll take it out.
