George: Hey. I just got off the phone with President Hagemeyer. This guy we're gonna have dinner with sounds pretty interesting. He made all of his money selling antistatic furniture for laboratories.
Sheldon: He's not even a scientist? He's just a furniture salesman?
George: Yeah.
Sheldon: What am I supposed to talk about?
George: Talk about whatever you want. Just... don't be insulting.
Sheldon: What if he says something I think is ridiculous?
George: Keep it to yourself.
Sheldon: What if you just said something I think is ridiculous? Because...
George: Okay, maybe we need to work a little on your conversation skills, like not calling people out for saying stupid things.
Sheldon: How am I supposed to practice that?
[cut to Sheldon answering the door to Billy Sparks:]
Billy Sparks: What's up?

George: And Sheldon's fine. You know what he's like. If someone took him, I'm sure they'll bring him right back.

Sheldon: There's going to be a lecture on carbon dating at the Natural Science Museum on Saturday. Who would like to take me?
George: You know what? I'd be happy to.
Meemaw: What happened to helping me at my yard sale?
George: Ooh, is that this Saturday? I'm sorry. I'm taking him to a lecture on, uh what is it? Carbonation?
Sheldon: Carbon dating. A method of determining the age of artifacts and fossils.
George: Hey, we could use that to figure out how old your grandma is.
Sheldon: That won't work. You can't carbon-date something that's alive.
George: Well, then, we'll just chop her down and count the rings.
Meemaw: Oh, George, did my "lump of clay" remark strike a nerve?
George: A little.

Georgie: A bill? Really?
George: Room and board, buddy.
Georgie: $50 a month for food?
George: The way you eat, I should've gone $50 a week.
Georgie: Laundry services?
George: Your poor mother has to touch your underwear.
Georgie: What's the $10 a month "peema" charge?
George: Oh, P-I-M-A, that's a "Pain in My Ass" tax. My way of getting compensated for you taking years off my life.

Georgie: See? They ain't allowed to dance, either.
Missy: It's like I'm watching my life.
Georgie: That's how I feel when I'm watching Top Gun.

George: Come on, Sheldon, think of it as a free dinner.
Sheldon: I'm a kid. All my dinners are free.

Dale: Now, what do you think young people talk about on their dates?
Meemaw: I don't know. But my knee's telling me it's gonna rain this weekend.
