Sheldon: Although Kirk is usually the one who saves the Enterprise.
Meemaw: Because he doesn't always follow the rules?
Sheldon: He even cheated on a test when he was a cadet. The Kobayashi Maru.
Meemaw: The what?
Sheldon: Kobayashi Maru. Kirk is a legend because of it.

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: Do you think a Spock could become a Kirk?
Meemaw: Well, in my experience, most people stay the miserable bastards they are their whole entire life. But I have seen some folks change.

Adult Sheldon: Despite my explanation that I was embracing my inner Kirk, my mother had me make amends for all my misdeeds. Starting in the library, where I had to reshelve hundreds of books. Well, to be honest, that one was a hoot.

Adult Sheldon: The amends got worse when Coach Wilkins made me climb the rope. Lacking any upper body strength, I hung there like a salami in a deli window.
