  Peter Parker: Ah, that's bad for me. I have a meeting for the Torch.
  Mary: The what?
  Peter Parker: The Torch, you know, the campus literary magazine. It comes out once a month.

  Peter Parker: I'll give you a copy of our magazine. So anyway, what about tomorrow? After lunch, baby?
  Mary: OK. See you around then.
