George Sr.: You want to explain yourself?
Sheldon: I'd rather just go to bed, since I have to be up in a few hours anyway.
George Sr.: Look, I understand you're tired, but that is no reason for you-
Sheldon: I'm not just tired. I'm exhausted. Everything hurts. I get up in the morning to do this job I don't even like. And I'm doing it just for the money, and it's not even a lot of money. I keep trying harder and harder, and it doesn't even make a difference. So if you're going to yell at me or punish me, let's just get it over with.
George Sr.: I'm not gonna punish you.
Sheldon: Why not? I deserve it.
George Sr.: Let me tell you about my day. I got yelled at by the principal for benching a linebacker who's flunking English. Then I got yelled at even more by the kid's parents. Then I had to break up a fight in the locker room. Got elbowed in the neck.
Sheldon: That's a rough day.
George Sr.: That was all before 10:00 a.m. So I get what you're going through. But you'll notice, I didn't come home and take it out on you.
Sheldon: No, you didn't.
George Sr.: I want you to get back in there, apologize to everyone, and finish your dinner.
Sheldon: Yes, sir.

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.
