Sheldon: Hello!
George: Oh.
George: What are you doing here?
Sheldon: I got called to the principal's office.
George: So did I. What, you do something wrong?
Sheldon: Not that I'm aware of. Did you?
George: I hope not.
Sheldon: Maybe it's good news.
George: Sheldon, you ever been called to the principal's office for good news?
Sheldon: Never.

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.

Sheldon: I think you tripped and hit your head.
Dr. John Sturgis: I'm a bit woozy.
Sheldon: I better test for concussion. What's your name?
Dr. John Sturgis: John Burgess Sturgis.
Sheldon: Burgess Sturgis? Great name.
Dr. John Sturgis: Thank you.

Mary: Remember, it's a school night, so his bedtime is 7:30.
Dr. John Sturgis: Mine, too!

Sheldon: Do you believe there's intelligent life in the universe?
Dr. John Sturgis: I have no doubt.
Sheldon: Why is that?
Dr. John Sturgis: The Drake Equation claims that there are at least 20 detectable civilizations in our Milky Way galaxy alone.
Sheldon: Interesting. My sister likes to say that I'm an alien.
Dr. John Sturgis: I've often been called that. Once by the praying mantis in my dream.
Sheldon: Maybe we are aliens.
Dr. John Sturgis: Perhaps. Or maybe people like you and me were the original inhabitants of Earth, and everyone else is from outer space.
Sheldon: Ooh, I like that better.
