Prof. John Robinson: [journal entry] Although we've survived the earthquake, and Maj.

[John and Don discover Dr. Smith taking a shower with the last of their water supply]
Prof. John Robinson: I ought to kick you clear into orbit for taking a shower at a time like this.
Dr. Zachary Smith: I couldn't wait another day. I was losing precious body fluids besides feeling very icky.
Maureen Robinson: Dr. Smith! Don't eat that!
[She knocks the fruit out of his hand]
Dr. Zachary Smith: Well! You didn't have to do that. There's plenty more.
Maureen Robinson: How many of these have you eaten?
Dr. Zachary Smith: It was only my second, and I must say it's delicious, a very exotic flavor. Now, you needn't worry. There's plenty for everyone, just don't worry at all about it.
Maureen Robinson: But you don't understand! This fruit hasn't been tested. It might be...
Dr. Zachary Smith: May be what? Tell me.
Maureen Robinson: Poisonous! Oh, WHY couldn't you have waited?
Dr. Zachary Smith: I know how you all feel about me! Another mouth to feed! Another thirst to quench! "Oh, yes, let's get rid of him! This is our chance." That's the way your evil minds worked, wasn't it?
Will Robinson: Gosh, it's not so bad being big. Think of all the marvelous things you'll be able to do. Like, gosh, you'll be able to get bird's eggs without even climbing.
Prof. John Robinson: Now, Smith, the doctor, probably knows more about the action of that fruit on the pituitary gland than any of us, but Smith, the victim, well, he's in a state of shock. He couldn't help himself even if he wanted to.
