There's not a day goes by I don't feel regret. Not because I'm in here, or because you think I should. I look back on the way I was then: a young, stupid kid who committed that terrible crime. I want to talk to him. I want to try and talk some sense to him, tell him the way things are. But I can't. That kid's long gone and this old man is all that's left. I got to live with that. Rehabilitated? It's just a bullshit word. So you go on and stamp your form, sonny, and stop wasting my time. Because to tell you the truth, I don't give a shit.
Memorizing Red's monologues?

Mathematicians won the war. Mathematicians broke the Japanese codes.. and built the Abomb! Mathematicians.. like you!
The stated goal of the Soviets is global communism. In medicine or economics.. in technology or space.. battlelines are being drawn!
To triumph we need results.. publishable, applicable results.. Now who among you will be the next Morse..? The next Einstein? Who among you will be the vanguard of democracy, freedom and discovery? Today we bequeath Americas future into your able hands.. Welcome to Princeton gentlemen..
