George: Oh, come on. You know how I feel about your mother meddlin' in our finances.
Mary: She wasn't meddlin', she was offering to help. And that computer is not some silly toy. Sheldon could use it for his schoolwork, and I could use it to organize my recipes.
George: You already got 'em organized on those little cards.
Mary: Yeah, like a cave person.

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.

Sheldon: And then they laughed at me for not knowing something that they knew. Who does that?
Mary: You do.
Sheldon: Well, this is no time for a teachable moment. Your child is hurting.
Mary: Sorry. [taps Sheldon's shoulder] There, there.
Sheldon: I guess that'll do. Now, how about a hot beverage?

Georgie: What are you doing?
George: Separating the whites from the colors.
Georgie: Whoa, that's racist.

Georgie: Maybe you should go across the street and apologize.
George: I can't do that.
Georgie: Why not?
George: 'Cause if I do, it sets a bad precedent.
Georgie: What's Nixon got to do with it?
George: What?
Georgie: You said "bad president," like Nixon. You know, this guy.

Meemaw: I could buy it for him, and then y'all could pay me back when you can.
George: Okay, Connie, now you're just insulting me.
Meemaw: Well, that was not my intention, but I'm glad to hear it.
