Meemaw: Wait, what's an "event horizon"?
Sheldon: It just means the edge.
Meemaw: Why not say "the edge"?
Georgie: The guitar player for U is called the Edge.
George: What does that have to do with anything?
Georgie: I'm participating in the conversation. You're just sitting there like a lump.
Meemaw: [snorts] "Lump."
Sheldon: Anyway, ordinarily, the particles would collide and destroy each other.
Dr. John Sturgis: But in this instance, they could exist simultaneously.
George: And what is the significance of that? [to Georgie] I can participate, smart-ass.
Georgie: Good job, lump.

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.

Georgie: Mornin'.
Mary: Mornin'.
Georgie: I slept in the nude last night. Felt every little breeze.
[Sheldon slides his food away]
Mary: Thank you for sharing that.
Georgie: You're welcome.

Adult Sheldon: [v.o.] We often regret the things we don't say. There's a lot of things I wish I had said to my dad while he was around. That I appreciated him. That I loved him. Which is why I'm grateful for the times I did tell him how I felt.
Sheldon: Tonight was fun.
George: Yeah? Why is that?
Sheldon: Dr. Sturgis was here. Everybody talked about science. It was nice.
George: It was.

President Hagemeyer: Sheldon, Dr. Sturgis quit right before the semester started. He left me in the lurch.
Sheldon: And this is your chance to be the bigger person.
President Hagemeyer: I don't want to be the bigger person. I'll be the small, petty person. That's way more fun.
Sheldon: Please? It would make me really happy if he came back. And you said yourself my happiness is important to the university.
President Hagemeyer: Are you trying to manipulate me?
Sheldon: Hey, being small and petty is fun.

Meemaw: Thanks for inviting John to dinner tonight.
Mary: Oh, my pleasure.
Meemaw: I've been a little bit worried about him. You know, with what happened last time.
Mary: At least he didn't seem unstable when I talked to him.
Meemaw: The man has a doctorate in science, and he's filling people's grocery bags.
Mary: He actually did a really nice job. He put the heavy things on the bottom. He kept the cold things together.
Meemaw: Mary.
Mary: Well, they don't always do that.
