Quotes6

  • Dr. Zachary Smith: When I was a child I, too, thought like a child, but when I became a man, I had to think like a man.
  • Will Robinson: I don't think it matters WHAT age you are: if you're dishonest you're dishonest, and that's all there is to it.
  • Prof. John Robinson: Tell us about the cage.
  • The Robot: Special thermo-genetic unit adjusts to the biological need of each imprisoned animal.
  • Maj. Don West: What's the range of temperature?
  • The Robot: From 300° above zero to 150° below zero.
  • Prof. John Robinson: What sort of animals live at those temperatures?
  • Dr. Zachary Smith: I hope we never have the misfortune to find out.
  • Dr. Zachary Smith: All we need to do is to have the Keeper allow us to come aboard his spaceship. I said before, there are seven of us. It would be a simple matter.
  • Maureen Robinson: No! Absolutely no!
  • Dr. Zachary Smith: I understand your objections, Mrs. Robinson, but sometimes violence is a necessity.
  • Maureen Robinson: Well, Dr. Smith, no matter how much I want to get off this planet, I won't resort to violence to do so.
  • Dr. Zachary Smith: In this situation, the end more than amply justifies the means.
  • Prof. John Robinson: Well, not to me it doesn't, and unless I'm badly mistaken, not to anyone else at this table, and that concludes the matter.
  • Dr. Zachary Smith: I want to talk to you, sir.
  • The Keeper: What could you say that would be of interest to me?
  • Dr. Zachary Smith: How would you like to add some new animals to your collection?
  • The Keeper: Are you referring to members of the Robinson party?
  • Dr. Zachary Smith: Certainly not, sir. I assure you they are a very poor selection indeed. But it's an entirely different story on Earth. The planet literally swarms with all sorts of strange creatures.
  • The Keeper: [wearied] Yes, I'm beginning to realize that.
  • Prof. John Robinson: [about to lock Smith in his cabin for the night] Hey, Dr. Smith, I think you'd better get inside. Don, you take the first watch.
  • Maj. Don West: All right.
  • Dr. Zachary Smith: Very well, I'll go, but I know I shan't sleep a wink. I'll need something to read.
  • Prof. John Robinson: [enthusiastically] Well, we'll get you a book.
  • Dr. Zachary Smith: I'm thirsty.
  • Prof. John Robinson: And a glass of water.
  • Dr. Zachary Smith: A little music might help to pass the time.
  • Prof. John Robinson: Oh. Well, you can have one of Penny's tapes.
  • Dr. Zachary Smith: And I'd like the robot to keep me company.
  • Prof. John Robinson: [shoving Smith in his cabin] Get inside!
  • Dr. Zachary Smith: [affronted] Really!
  • Dr. Zachary Smith: I'm still in my cage, madam. I've just been fed, so I am not dangerous. You may open the door.
