Mary: The important thing is, is that you both need to keep this quiet. This is family business.
Sheldon: I have to keep a secret? I'm not good at those.
George: It's not a secret. No one's gonna ask you about it. It's just a thing you don't need to bring up.
Sheldon: But what if I do?
George: What if you don't?
Sheldon: But now it's all I can think about. What if my mouth loses control?
Mary: You're good at keeping promises, right?
Sheldon: Very. Great.
Mary: Then promise you won't tell anybody.
Sheldon: That's an interesting work-around. However...
Mary: You're not telling anyone.
Sheldon: Fine.

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.

Pastor Jeff: Come on up here, Sheldon. Let's hear what you got.
Sheldon: I've spent the last week studying what people believe, and I've come to a conclusion.
Pastor Jeff: And what's that?
Sheldon: I'm starting my own religion.
Pastor Jeff: I'm sorry, what?
Sheldon: I'm calling it Mathology. It's based on a universal binary system.
Pastor Jeff: That's terrific, Sheldon, but this is a Baptist Sunday school.
Sheldon: I know, I'm here to convert everybody. Any takers?
Pastor Jeff: Okay. Let's go have a talk with your mom.
Sheldon: The only sin in Mathology is being stupid.

Mary: Too bad. We are going.
Sheldon: Class is starting tomorrow. I'm not going anywhere.
Mary: Sheldon, do not argue with me. You are going home.
Sheldon: Mom, the people of Germany are obsessed with rules and devoid of humor. I am home.

Missy: [groans] Mom and Dad are still really upset.
Sheldon: With good reason. She's awfully old to be having a baby.
Missy: Is it really dangerous?
Sheldon: Not with modern science, but back in pioneer times, we'd be burying her down by the crick.
Missy: I'm just saying they're cranky enough, so don't be a pain in the ass.
Sheldon: I'm always on my best behavior. You're the hormonal firecracker around here.
Missy: Sheldon.
Sheldon: And thar she blows. Moby Dick. It's a book.

George: Where the hell's my travel mug?
Mary: I think Georgie took it, dear.
George: That son of a gun.
Mary: Missy, your father's gonna take you to school today.
Missy: Thanks, Daddy. I hope it's not too much trouble.
George: [smiles] No trouble at all, my little angel. [Mary smiles at Missy, too]
Sheldon: [to Missy] Why'd you say they're cranky? They're fine.

Mary: [chuckles] Well, at this point, it doesn't matter, because she doesn't want to get married.
Pastor Rob: Well, I can talk to her if you want.
Mary: Mm.
Pastor Rob: I'm pretty good with young people.
Mary: She's 29.
Pastor Rob: Also pretty good with people my own age. [Mary chuckles]
