Mary: You're really making him live out there?
George Sr.: He's not gonna last one night in that nasty thing.
Mary: Have you seen that boy's room?

Sheldon: Regardless, I'm not interested in making any more friends.
Mary: Oh, I don't think that's how you really feel.
Sheldon: It is. From now on, it's a hermit's life for me.
Mary: I bet, when you grow up, you will be surrounded by lots of smart, wonderful friends.
Sheldon: I can't see that happening.

Sheldon: Mom, when should I be expecting my testicles?
Woman: [turns around] What is wrong with him?
Mary: Nothing is wrong with him. Now turn around before I knock your lights out.
Sheldon: Hello.

Mary: Sheldon Lee Cooper, if you don't finish that pork chop, I swear I will chew it up and spit it in your mouth like a mama bird.
Missy: Do it, Mom. Do it.

Missy: Why don't you believe in God? [Sheldon raises his hand] Sheldon.
Sheldon: Because science explains the universe without the need of inventing a supernatural being.
Missy: But how do you know for sure He doesn't exist?
Sheldon: Ooh. [raises hand]
Missy: Stop that.
Sheldon: The burden of proof isn't on me. If I said there was an invisible monkey in the room with us, you shouldn't believe me just because you can't prove me wrong.

Pastor Jeff: Now, for a psalm 100 bookmark, who can name the apostles? [Billy raises his hand] Billy.
Billy Sparks: Sleepy, Grumpy, Doc...
Pastor Jeff: Those are dwarves. Anyone else?

George Sr.: Just go get your money back and buy a different car.
George Jr.: No.
George Sr.: Georgie, I'm not playing around.
George Jr.: Neither am I. I bought it with my own money, and you don't get a say.
George Sr.: As long as you live under my roof, I get plenty of say.
George Jr.: Fine. I'll move out.
George Sr.: And where you gonna go?
George Jr.: I'll live in the van.
George Sr.: [laughs] You know what? It was only a matter of time before you lived in a van. Have at it.
George Jr.: Scooby-Doo lived in a van, and he turned out fine.
