  • Trivia

  • Quotes

    • Penfield: (about Tooner) We gotta get this guy, he made me itch in front of strangers!

    • Charlie: How about a truce?
      Penfield: Is this some game theory trick?
      Charlie: If it was, I would be using the fourth-level altruism ploy, right?

    • Charlie: Seriously, every time I come up with something new, in the back of my mind I'm thinking, 'Penfield's gonna tear this apart.'
      Penfield: No, you're just saying this to be nice.

    • David: (in a movie trailer voice-over voice) In a world where mathematicians go mano y mano with a killer...
      Colby: (in the same type of voice)...this time, it's personal.

    • Penfield: God, why am I so stupid?
      Charlie: You want answers one through fifty? Or fifty through one hundred?

    • Charlie: I think going to temple's an interesting choice. I have nothing negative to say about that.
      Don: Okay.
      Charlie: At least it's not a monastery.

    • Nikki: I get it. You don't want us making life miserable for innocent grad students.
      Penfield: That's what professors are for.

    • Larry: Enough! Surely two eminent mathematicians can find ways to calmly discuss theory.
      Charlie: We're not discussing theory.
      Penfield: No, we're talking hamburgers.

    • Charlie: Talking about set theory. Let's say this circle represents objects visible in the night sky. And this circle represents objects that generate light. Where they overlap is a subset: objects visible in the night sky that generate light, like a star.
      Penfield: How do you not have your own show on PBS?

    • Nikki: That mean anything to you?
      Charlie: Not immediately. But there might be a subset within the superset.
      Nikki: And for those of us who don't speak math?

  • Allusions

    • Colby: (to David, as they are walking through Tooner's neighborhood, looking for him) Everybody knows our name, but nobody's glad we came.

      Colby's remark is an allusion to a line from the theme song from the TV series Cheers - "Sometimes you want to go where everybody knows your name, and they're always glad you came."
