- Will Robinson: But why work when the machine can do it FOR you?
- Prof. John Robinson: Will, up to now, this family's been getting along very well. We have respect and love for one another - and you can not wish for those things with THAT. Now we get this, a machine that makes dreams come true, and instead of making us happier, it sows the seeds of discontent, mistrust and indolence. I said "a machine that makes dreams come true..." Nightmares can also be dreams.
- Will Robinson: I brought you some breakfast.
- Dr. Zachary Smith: Ah, most kind of you, my boy - ah - but as an expert woodsman I find no difficulty living off the land.
- Will Robinson: You said all you wanted to do was check out the machine.
- Dr. Zachary Smith: That's exactly what I've been doing.
- Will Robinson: For four days?
- Dr. Zachary Smith: Well, you see, uh, science is a matter of, uh, trial and error. I had to be sure there was no danger.
- Will Robinson: Have you found any?
- Dr. Zachary Smith: There are certain problems, uh, but as soon as they're ironed out...
- Will Robinson: When will that be?
- Dr. Zachary Smith: Uh... eventually, my boy. Eventually.
- Will Robinson: What you really mean is - never, don't you, sir?
- Dr. Zachary Smith: If I had the intelligence of a goose, I'd still be a genius compared to you!
- Maj. Don West: Yeah, well, all that brainpower you're always talking about - it must be well-hidden because nobody ever notices it except yourself!
- Prof. John Robinson: We don't have a farm anymore.
- Will Robinson: What happened to it?
- Prof. John Robinson: It died of neglect!
- Maj. Don West: I don't know how the others feel, Smith, but I'm fed up to the teeth with you! Every time something goes wrong around here, you're always at the bottom of it. You're nothing but a troublemaker and the sooner we get rid of you the better off we'll all be.
- Dr. Zachary Smith: Now, uh, what about a piece of delicious French pastry? Can't make up your mind?
- Will Robinson: I was just thinking about Penny and Judy and everyone else.
- Dr. Zachary Smith: So?
- Will Robinson: It wouldn't be fair for me to have cake when they couldn't.
- Dr. Zachary Smith: A noble gesture but hardly realistic.
- Maj. Don West: [harshly] What do YOU want?
- Dr. Zachary Smith: Now, is that a way to greet Santa Claus, particularly when he has gifts for you all?
- Maureen Robinson: [to John] She was listening to her tapes.
- Penny Robinson: Oh, you should hear them, Dad. They're absolutely wonderful. Bach, and Mozart, and Beethoven...
- Prof. John Robinson: Well, I won't argue with your choice but, uh, do you have anything there by Deceit?
- Penny Robinson: Deceit? Don't think I've ever heard of THAT composer.
- Prof. John Robinson: Oh, perhaps you don't recognize the name. Uh, maybe these names will help - Cheat? Lie? Trick? D'you recognize the composer or do I have to go on?
- Dr. Zachary Smith: I have the thought machine, and I can have anything I want. All I have to do is think and - POOF, heh-heh - it's mine.
- Dr. Zachary Smith: I say, Zachary, would you like a servant? Yes, Zachary, you WOULD like a servant.
