George: Sheldon, what are you doing here?
Sheldon: They wouldn't let me use the phone in the principal's office.
George: Who are you calling?
Sheldon: Dr. Sturgis. It's a math emergency.
George: Don't you think you should've asked my permission first?
Sheldon: It's ringing. Yes or no?
George: You know what? I don't care.

Mary: So he's really good to graduate?
Principal Petersen: He sure is. I got to tell ya, usually when kids leave school after two years, it's not for college. It's for prison or pregnancy.
George: Well, between Georgie and Missy, we may hit the trifecta.
Mary: George!
George: Well, I'm not rooting for it. It's just a thing that could happen.

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.

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.

Adult Sheldon: Dr. Sturgis was a wise man. It was a learning opportunity. And when the day comes that I'm wrong, I fully plan to admit it.

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...
