Missy: Ew! You were doing it, too?
Mary: Well, it's... different. Your father and I are married, so when we're... amorous...
Missy: I don't want to hear about this.
George: [enters] [yawns] What's for breakfast? I am hungry. [chuckles]
Missy: Nope. [gets up and walks away]
George: What's her problem?
Missy: Thin walls.
Mary: [sighs] She heard Mandy and Georgie... You know.
George: Oh [groans] At least she didn't hear us. [Mary sighs]

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.

[After Sheldon storms off with his upgraded computer:]
Jim: He gonna be okay?
George: Oh. Tonight, sure. Big picture? [shrugs]
Adult Sheldon: I've got a hot wife and a Nobel Prize. I turned out fine.

Mary: [on the phone] Hi, Pastor Jeff. Can you come over right now? I need you to save someone's soul.
[Cut to Mary opening the front door to Pastor Jeff, who is holding his bible:]
Pastor Jeff: Whose soul needs saving? Is it Sheldon? I've been waiting for this.
Mary: No. We're still praying for him. Come in, we don't have much time.

Georgie: It's for my daughter. Mom baptized her in the kitchen sink, and Mandy's mom did it in a Catholic church.
Sheldon: Sure. Baptists versus Catholics. Much blood was shed over that in the 1500s.
