Dr. Zachary Smith
- 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!
- 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?
- 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.
