Paige: Well, I think my parents are getting a divorce.
Sheldon: Why?
Paige: They fight all the time.
Sheldon: About what?
Paige: Mostly me.
Sheldon: Hmm. That's too bad. I guess I'm lucky.
Paige: Why?
Sheldon: I'm the glue that holds our family together.

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.

Mary: Mom, can you make the salad?
Meemaw: Sure.
George: Hey, don't put in any of those little tomatoes.
Meemaw: Hey, I don't tell you how to impersonate a lump of clay. You don't tell me how to make a salad.

Paige: Sheldon?
Sheldon: Paige?
Paige: I'm so happy to see you. Are you happy to see me?
Sheldon: Not immediately.
Paige: That's okay. I'm happy enough for both of us.

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.
