George Sr.: 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 Sr.: 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.

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

George Jr.: Maybe you should go across the street and apologize.
George Sr.: I can't do that.
George Jr.: Why not?
George Sr.: 'Cause if I do, it sets a bad precedent.
George Jr.: What's Nixon got to do with it?
George Sr.: What?
George Jr.: 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 Sr.: Okay, Connie, now you're just insulting me.
Meemaw: Well, that was not my intention, but I'm glad to hear it.
