George Sr.: Your mother's taking him to school.
Sheldon: That's not very efficient. Our car's already going there.
George Sr.: Not that it's any of your business, but I needed a break from your brother.
Sheldon: I certainly understand that. He's an acquired taste. Like Grape-Nuts. The first time I tried it, I thought I was eating gravel. But then I put a little sugar on it and let it get soggy. Now it's in my top six cereals.
George Sr.: I'll try soaking Georgie in a bowl of milk.
Sheldon: Sarcasm?
George Sr.: Yeah.
Sheldon: I had a feeling. The clue was you don't normally put people in bowls of milk.

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.

Adult Sheldon: I've fought many digital battles in my life, but none are as memorable as this first one with my Meemaw. By handing me the controller, she was telling me she believed in me. That inside my small, fragile frame beat the heart of a hero.

Adult Sheldon: Since that night, I've battled orcs, zombies, Nazis, Nazi-zombies, a dinosaur in a go-kart, and played Van Halen's "Hot for Teacher" on a stringless, plastic guitar. But nothing would ever compare to that first quest with my meemaw. Although Leonard pulling a groin muscle doing Dance Dance Revolution was a close second.

Adult Sheldon: Over the next few days, I ran to my Meemaw's house so we could save the 8-bit princess. And if it's unclear how important this was, let me say it again: I ran.
