George: Mr. Spock! He flies around all the time in that spaceship. He's not afraid, is he?
Sheldon: I'm not Mr. Spock.
George: No, but-but I've seen you pretend to be him. Could you do that right now? You be Spock, I'll be Kirk.
Sheldon: Maybe.
George: Okay, Mr. Spock. Your first order is to return to your seat.
Sheldon: Aye, Captain.

George: And Sheldon's fine. You know what he's like. If someone took him, I'm sure they'll bring him right back.

Georgie: A bill? Really?
George: Room and board, buddy.
Georgie: $50 a month for food?
George: The way you eat, I should've gone $50 a week.
Georgie: Laundry services?
George: Your poor mother has to touch your underwear.
Georgie: What's the $10 a month "peema" charge?
George: Oh, P-I-M-A, that's a "Pain in My Ass" tax. My way of getting compensated for you taking years off my life.

Georgie: You know what else is nice?
George: Hmm?
Georgie: I get to learn from all your parenting mistakes.
George: I'm starting to think letting you live this long was one of 'em.
Georgie: Like that. I'd never say something so awful to my kid. [George scoffs] Thanks, big guy.

Sheldon: Dad, the university offered to pay for us to go to California! They're even putting us up in a hotel.
George: You're kidding.
Missy: We're going to California?
Sheldon: No, just me and Dad.
Missy: That's fair. I'm so happy for you.
Adult Sheldon: Sometimes sarcasm was laid on so thick even I could detect it.
Sheldon: Thanks!
Adult Sheldon: This was not one of those times.

Sheldon: Dad, good news. Airline tickets to California are more affordable than you think.
George: Sheldon, we're not going.
Mary: What's all this about?
Sheldon: Stephen Hawking is giving a lecture at Caltech. If we leave on Wednesday and are willing to make four layovers, in Boise, Denver, Albuquerque and Fargo, we can get there for only $95 each.

George: I have a job. I can't just leave in the middle of the week.
Sheldon: Well, then what about Mom?
Mary: Sorry, Shelly, we're not in a position to do this.
Sheldon: But Stephen Hawking's my hero. Imagine if you got a chance to see Jesus or Dad got to meet the man who invented beer.
