George: What's going on?
Mary: That was Dr. Linkletter. He says that Sheldon is spending too much time with him.
George: Better him than us, right?
Mary: [sighs] He's suggesting that Sheldon try and find some friends on campus.
George: Makes sense.
Mary: I'm just worried that he's gonna be hanging out with people who are drinking and going to parties.
George: Like he's gonna make friends with the cool kids.

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: I'm hurt Dr. Linkletter doesn't want me as a friend.
Mary: Understandable.
Sheldon: I'm also angry. I don't like having two feelings at once. It's annoying. Great, annoyed. That's three.

[title: Sci-Fi Club:]
Sheldon: So, what kind of activities does the Science Fiction Club engage in?
Greg: Well, this Friday we're having a screening of Star Wars on laser disc.
Sheldon: I thought this was the Science Fiction Club.
Greg: It is.
Sheldon: Star Wars is science fantasy. The Force is basically magic. At that point, you might as well be watching The Hobbit.
Greg: That's next week.
Sheldon: This is madness.

Dr. Willard: The Moho lies between the mantle and the crust, and...
Sheldon: Excuse me, I'm looking for Dr. Linkletter.
Dr. Willard: He's not here.
Sheldon: Sorry for wasting your time. Oh, this is geology. You're already wasting your time.
