George Sr.: This is the moment we lost that game. But one bad play doesn't mean you give up. We had plenty of time to turn it around, but y'all decided it was over. I don't want to ever see that happen again. Next time something seems out of your reach, you do not quit. You just dig deeper.
Sheldon: [appears out of nowhere] Does that mean if I find an affordable flight to California, we can go?

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: Dad, the university offered to pay for us to go to California! They're even putting us up in a hotel.
George Sr.: You're kidding.
Missy: We're going to California?
Sheldon: No, just me and Dad.
Missy: That's fair. I'm so happy for you.
Adult Sheldon: Sometimes sarcasm was laid on so thick even I could detect it.
Sheldon: Thanks!
Adult Sheldon: This was not one of those times.

Sheldon: Dad, good news. Airline tickets to California are more affordable than you think.
George Sr.: Sheldon, we're not going.
Mary: What's all this about?
Sheldon: Stephen Hawking is giving a lecture at Caltech. If we leave on Wednesday and are willing to make four layovers, in Boise, Denver, Albuquerque and Fargo, we can get there for only $95 each.

George Sr.: I have a job. I can't just leave in the middle of the week.
Sheldon: Well, then what about Mom?
Mary: Sorry, Shelly, we're not in a position to do this.
Sheldon: But Stephen Hawking's my hero. Imagine if you got a chance to see Jesus or Dad got to meet the man who invented beer.
