Nash:
In competitive behavior someone always loses.
Charles:
Well, my niece knows that, John, and she's about this high.
Nash:
See if I derive an equilibrium where prevalence is a non-singular event where nobody loses, can you imagine the effect that would have on conflict scenarios, arm negotiations...
Charles:
When did you last eat?
Nash:
...currency exchange?
Charles:
When did you last eat? You know, food.
Nash:
You have no respect for cognitive reverie, you know that?
Charles:
Yes. But pizza - now, pizza I have enormous respect for. And of course beer.
[leaves]
Nash:
[throws stuff down and follows] I have respect for beer. I have respect for beer!


Hansen:
Cowards, all of you. Come on. Whoever wins, Sol does his laundry for the semester.
Sol:
Does that seem unfair to anybody?
Bender:
No, not at all.


Nash:
Classes will dull your mind, destroy the potential for authentic creativity.


Charles:
That Isaac Newton fellow was right.
Nash:
He was on to something.
Charles:
Clever boy.


Charles:
So what's your story? You the poor kid that never got to go to Exeter or Andover?
Nash:
Despite my privileged upbringing, I'm actually quite well-balanced. I have a chip on both shoulders.


Nash:
There has to be a mathematical explanation for how bad that tie is.


Hansen:
So how about it, Nash? You scared?
Nash:
Terrified... mortified... petrified... stupefied... by you.


Charles:
Nothing's ever for sure, John. That's the only sure thing I do know.


Nash:
I've made the most important discovery of my life. It's only in the mysterious equation of love that any logical reasons can be found. I'm only here tonight because of you. You are the only reason I am... you are all my reasons.


Nash:
What truly is logic? Who decides reason? My quest has taken me to the physical, the metaphysical, the delusional, and back. I have made the most important discovery of my career - the most important discovery of my life. It is only in the mysterious equations of love that any logic or reason can be found. I am only here tonight because of you
[looking at and speaking to Alicia]
Nash:
You are the only reason I am. You are all my reasons. Thank you.
[applause from audience]


Charles:
Her husband was too drunk to know he was too drunk to drive.


Nash:
[to Charles] The prodigal roommate revealed. "Saw my name on the lecture slate." YOU LYING SON OF A BITCH!
Dr. Rosen:
Who are you talking to? Tell me who you see.
Nash:
How do you say "Charles Herman" in Russian?
