George Sr.: You know how much it's gonna cost to fix that fridge?
Sheldon: $200. I have really good hearing.
George Sr.: Do you have any idea how hard I work for the money we get?
Sheldon: I'm sorry.
George Sr.: I don't care how long it takes. You're gonna pay me back every cent of this.
Sheldon: Yes, sir.
George Sr.: I am very disappointed in you.

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

Sheldon: Dad, do you believe that fossils are millions of years old?
George Sr.: I guess. Why?
Sheldon: Well, Mom believes the world was only created 6,000 years ago.
George Sr.: Yeah. So?
Sheldon: Are these differences a sticking point in your marriage?
George Sr.: Not at all.
Sheldon: Why?
George Sr.: Simple. We never talk about it.
Sheldon: So you just avoid discussing topics you don't agree on?
George Sr.: At all costs.

Meemaw: I bowled a new high score last night.
George Sr.: Nice.
Meemaw: I got two turkeys.
Missy: What's a turkey?
Meemaw: It's three strikes in a row.
Missy: Why do they call it a turkey?
Meemaw: Well, when they first invented bowling, they used to just throw frozen turkeys at the pins. Eventually, they switched to balls to cut down on the smell.
George Sr.: Why you lying to her?
Meemaw: I find it keeps my mind sharp.

Adult Sheldon: Ignoring things that irritate me isn't my strong suit. Obsessively fixating on them, now that's what gets me out of bed in the morning.

Adult Sheldon: My father's wisdom touched me deeply. Which is why, to this day, no matter what I'm going through, I am never irritating or abusive to any of my friends or loved ones. Ask them. They'll tell you.

Billy Sparks: Hey, Sheldon.
Sheldon: Hello, Billy.
Billy Sparks: Are you our new paperboy?
Sheldon: Yes, I'm joining the work-a-day world.
Billy Sparks: I work, too! I take care of our chickens.
Sheldon: Don't get the wrong idea. When I grow up, I plan on being a theoretical physicist.
Billy Sparks: Cool. I'm sticking with chickens.
Sheldon: All righty then. Have a nice day.
Billy Sparks: You, too. [looking at the newspaper] Oh, cool, it's Monday.
