Dr. Zachary Smith
- Dr. Zachary Smith: Besides, I owe it to myself to set the record straight when we return to Earth.
- The Robot: You will have to tell a few whoppers to do that, Dr. Smith.
- Dr. Zachary Smith: Quiet, you obsolete oaf!
- Sgt. Smith: There will be no apology , Smith. We have just checked you out. Your name is Zachary Smith?
- Dr. Zachary Smith: Of course it is.
- Sgt. Smith: Mine is Horatio Smith, Smith. And whether I like it or not--and I don't--you are my great-great-great-great grandfather.
- Dr. Zachary Smith: Am I in--I am? Oh, good heavens. Oh, my dear boy. You are my great-great-great-great grandson? Well, let me look at you. Yes. I can see the resemblance. I think I'm going to cry. What a magnificent specimen of manhood you are--just like me! What a credit to the name of Smith!
- Sgt. Smith: Except that Zachary Smith has shamed all the Smiths, Smith. You know what it's like to live under a cloud? To have a finger of scorn pointed at you... because you-- yes, you-- besmirched the family name?
- Dr. Zachary Smith: I? Are you suggesting that the family name was besmirched by me?
- Sgt. Smith: Were you or were you not the fifth columnist in the Jupiter expedition?
- Dr. Zachary Smith: Certainly not.
- Sgt. Smith: Were you or were you not the master saboteur?
- Dr. Zachary Smith: No.
- Sgt. Smith: Were you or were you not the sly, Machiavellian menace during the entire Robinson voyage?
- Dr. Zachary Smith: Well, I...
- Sgt. Smith: Answer me! Answer me-- yes or no?
- Dr. Zachary Smith: How dare you!
- Dr. Zachary Smith: [Talking to the Robot] Did you hear these foul slanders?
- The Robot: I did, and they are not slanders.
