Missy: This is too complicated. I'm just gonna keep rubbing this thing on my bat and kicking butt.
Mary: Okay, that is it. Take it off.
Missy: No, I need it. The game's Saturday.
Mary: There are more important things than baseball. Now, hand it over.
Missy: God, cover your ears. Damn it.
Mary: Missy Cooper! You are not ready for that. You give that back. Oh, you... Get!

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.

George Jr.: Should I be wearing all that?
Sheldon: I recommend it. Those rocks are filthy.
George Jr.: I'm good. God made dirt. Dirt don't hurt.

George Jr.: Tell me, Sheldon.
Sheldon: It occurred to me that a good way to generate a positive cash flow would be to curate popular songs and make them available in a digital form. Possibly on a small device that could also be used as a phone or even a camera.
George Jr.: Right. [mocking] A phone, camera, music machine. Get out of here.

George Jr.: "Sell blood or non-vital organs."
George Sr.: Mm, give 'em your brain. You're not using it. [Sheldon laughs] I think that's the only time I've ever heard you laugh.
Sheldon: That's the only time you've ever been funny.
