"I think that Tammy, her monologue is completely optimistic, totally [looking] to a better place—the cosmos—and she has learned so much from this experience. And I think that Urp, in his farewell speech to these pathetic lifeforms, gives a real strong hint that there are darker days ahead. It's a pretty good indication of where things were."

"Klaatu: You have faith, Professor Barnhardt?"

"I am leaving soon, and you will forgive me if I speak bluntly. The universe grows smaller every day, and the threat of aggression by any group, anywhere, can no longer be tolerated. There must be security for all or no one is secure. Now, this does not mean giving up any freedom except the freedom to act irresponsibly. Your ancestors knew this when they made laws to govern themselves and hired policemen to enforce them. We of the other planets have long accepted this principle. We have an organization for the mutual protection of all planets and for the complete elimination of aggression. The test of any such higher authority is, of course, the police force that supports it. For our policemen, we created a race of robots. Their function is to patrol the planets—in space ships like this one—and preserve the peace. In matters of aggression, we have given them absolute power over us; this power can not be revoked. At the first sign of violence, they act automatically against the aggressor. The penalty for provoking their action is too terrible to risk. The result is that we live in peace, without arms or armies, secure in the knowledge that we are free from aggression and war—free to pursue more profitable enterprises. Now, we do not pretend to have achieved perfection, but we do have a system, and it works. I came here to give you these facts. It is no concern of ours how you run your own planet. But if you threaten to extend your violence, this Earth of yours will be reduced to a burned-out cinder. Your choice is simple: Join us and live in peace, or pursue your present course and face obliteration. We shall be waiting for your answer; the decision rests with you."

"[To Kroenen] You killed my father! Your ass is mine!"

"Hey, Myers, you're a talker. What's a good word, a solid word for "need"?"

"It's not– It's not what you think. Plus, you're nine. You're too young to be giving me advice."

"[To Sammael] Listen, Sammy, I'm not a very good shot, but the Samaritan here uses really big bullets. So what do you say we work this out in a nice, peaceful–? [Sammael runs off] Oh, crap."

"Damn! Would you please be a little more careful?"
