George: Georgie, how'd you do on that math test today?
Georgie: It was tough. I don't know.
Sheldon: I'm sorry I wasn't more help.
Georgie: Me, too.
Mary: That's all right, baby, you tried.
Missy: Yeah. It's okay, baby.

Sheldon: This isn't over.
Georgie: Oh, yeah? What are you gonna do?
Sheldon: All right, maybe it's over.

Sheldon: So what do you think?
Meemaw: I don't think you should let it bother you very much. I mean, there's always gonna be people in this world who are playing fast and loose with the rules. And your brother's one of them.
Sheldon: That's how Captain Kirk is on Star Trek.
Meemaw: Well, there you go, and he's, like, the main guy on that show.
Sheldon: No, Mr. Spock is the main guy.
Meemaw: I stand corrected.

Sheldon: Although Kirk is usually the one who saves the Enterprise.
Meemaw: Because he doesn't always follow the rules?
Sheldon: He even cheated on a test when he was a cadet. The Kobayashi Maru.
Meemaw: The what?
Sheldon: Kobayashi Maru. Kirk is a legend because of it.

Coach Wilkins: Happened to me while I was in the Army. I was in a bar in Georgia, tried to lift up this big gal. Swear I could hear something pop down there.

Professor Proton: [on TV] Today, we're going to learn about Sir Isaac Newton.
