Georgie: What's a math emergency?
George: That's when things don't add up. Oh, come on, guys. That was a good one.

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.

George: I may not understand exactly what's going on with you and Dr. Sturgis, but you can't be rude to an adult.
Sheldon: What if they're wrong?
George: Doesn't matter. There are plenty of stupid people in the world, but when they're older than you, you got to show them respect.
Sheldon: I understand, sir. Thank you for your incredibly wise advice.
George: Okay.
Missy: Did you just call Dad stupid without calling him stupid?
Sheldon: Yes.

Ms. Ingram: Today we're gonna work on interior angles of a convex polygon. Georgie, where's your brother?
Georgie: I don't know, do you really want him here?
Ms. Ingram: Convex polygons are polygons...
