Mr. Givens: Well, if Star Trek is so great, how come Lost in Space kicked its butt in the ratings? [all oohing]
Nathan: Well, if Lost in Space is so great, how come no one's ever remade it?
Sheldon: That's true, they're still making Star Trek movies and a new series.
Nathan: Yeah, which is even better than the original. [all oohing]
Sheldon: I'm sorry, what did you say?
Nathan: You heard me, Star Trek: Next Gen is better than Original Series.
Mr. Givens: Lost in Space brought me hours of happiness as a child, you... jerks.

George: Hey, Hubert. Was Sheldon in class today?
Mr. Givens: Nope. Haven't seen him all week.
George: Weren't you gonna say anything?
Mr. Givens: I didn't want to jinx it.

Mr. Givens: Caltech? Fantastic.
Sheldon: For Caltech? I know.
Mr. Givens: Mm. Well, I'm sure you're gonna do great things.
Sheldon: I hope so. I intend to. I'm being modest. I will.
Mr. Givens: You're taller, but you're still the same.
Sheldon: It's fun, isn't it?
Mr. Givens: Okay. Good luck at Caltech, Sheldon.
Sheldon: I don't believe in luck.
Mr. Givens: Well, here's hoping that a random universe works out in your favor.
Sheldon: Thank you. Bye.
Mr. Givens: Hmm. [to his class] That young man might change the world someday. Or blow it up. Who's to say?

Sheldon: Mr. Givens, I just wanted you to know that I'm still working hard on my campaign to get more funding for the science department.
Mr. Givens: Oh, great, 'cause I've got to dig up tomorrow's worms myself.

Sheldon: Mom, I know what I want to do for spring break. What happened to your face?
Mr. Lundy: Told you, people take notice.
Mary: This is for my new job.
Sheldon: Is your new job fighting Batman? Because you look like The Joker.

George: Sales is a tough racket, Mare.
Georgie: Yeah. It ain't as easy as I make it look.
Mary: Well, I think I'd be good at it.
Georgie: You sure? Sometimes you got to do a little fibbin'.
Mary: I would do it without that.
Georgie: And you got to have people skills.
Mary: I have people skills.
Georgie: Do you?
Mary: I'd like to throw my dinner roll at your head right now, but you don't see me doing it.

Mary: I'm not buying it. I'm thinking about selling it.
George: You?
Mary: Yes, me. Wouldn't hurt to have extra money.
Sheldon: But you already have two jobs... church and mom.
Mary: Well, that second one doesn't pay much.
Sheldon: I do your taxes. The first one doesn't either.
