Norman Goodman: I would be happy if Jerry had no emotions whatsoever. Because the thing of it is once you go down that road... here's Jerry, an emotional being cooped up for 300 years with no one to talk to... none of the socialization, the emotional growth that comes from contact with other emotional beings.
Norman Goodman: What happens if Jerry gets mad?
Norman Goodman: Can I ask you something about this reflective surface?
Barnes: Yeah, it appears to be mercury, doesn't it? Except mercury is liquid at this temperature.
Norman Goodman: Oh, no. That's not what I'm talking about. What worries me is that it's reflecting everything but us.
Norman Goodman: What is it, Harry?
Dr. Harry Adams: Take a look. It's chipped.
Captain Harold C. Barnes: Alright, it's chipped - so what?
Dr. Harry Adams: Well I thought you said this thing wouldn't damage when it crashed and that this titanium alloy was so superstrong there's no way you can hurt it.
Captain Harold C. Barnes: I did.
Dr. Harry Adams: So how come it chips when this scientist just bangs on it with a hammer?
