NASA Director: Thanks, kid. You really saved my bottom.
Sheldon: Tell your bottom it's welcome.

Mary: Let's say grace.
Sheldon: Hang on, safety first. [puts mittens on]
George Jr.: When are you gonna get over that?
Sheldon: I would think recent events would make you value protection.
Mary: Enough.

Ms. MacElroy: Now, can anyone tell me why Melville shifts the narrative voice from Ishmael to Ahab? [Ms. MacElroy waits for somebody else to raise their hand] Sheldon.
Sheldon: I have a tummyache. I'd like to see the nurse.
Derek: A "tummyache"?
Sheldon: Yes, Derek, I have a tummy and it aches. Ergo, tummyache.
Derek: Ergo?
Sheldon: It's Latin, Derek.
Ms. MacElroy: Go to the nurse.
Sheldon: And to answer your question, the shifting point of view grants the reader a broader perspective of events than typically allowed by first-person narration.
Ms. MacElroy: Where were we?
Sheldon: And "ergo" is Latin for "hence," Derek.

Missy: What's it like to not believe in God?
Sheldon: It's great. Big fan.
Missy: Are you ever afraid you're wrong?
Sheldon: About religion? Never. About other things? Also never.

Sheldon: I've been corresponding with Dr. John Sturgis at East Texas Tech. He said I could audit his course.
Meemaw: You're pen pals with a stranger? Is this okay?
Sheldon: He's not a stranger. He's a famous scientist. He carbon-dated the oldest human feces.
Meemaw: That ain't strange.

Mary: Now, Shelly, I appreciate that you want to expand your horizons, but how would you even get there? The school's an hour away. I'm working, your dad's working.
George Jr.: Again, who cares? Let him go.
Missy: He could hitchhike.
George Jr.: Perfect.

Meemaw: So, how was everybody's day?
Sheldon: I'm done with high school.
George Sr.: What does that mean?
Sheldon: Well, I don't learn anything there, and I don't want to go anymore.
Mary: Well, where do you think you're gonna go?
George Jr.: Who cares? Let him go.
