Adult Sheldon: The next day, I got my cast off. In a world where I valued symmetry,
I was relieved to see that both my arms were as pale and skinny as ever. But this Texan had unfinished business to tend to.
Missy: Want me to get you started?
Sheldon: No, I can do it.
Adult Sheldon: And I did do it. I rode my bike without training wheels like an adult. It would take more than a chicken or the threat of a fractured bone to scare me. It would take a brown beast named Scraps. [dog barks]
Sheldon: Aah! Mommy?!
Adult Sheldon: I rode my bike 11 miles that day.
Sheldon: Mommy!

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.

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.

Mary: Sheldon, faith means believing in something you can't know for sure is real. And right now, I am struggling with that.
Sheldon: So you don't believe in God anymore?
Mary: That isn't something for you to worry about. I need to figure this out myself.
Sheldon: Can I help? Maybe I could provide a fresh perspective.
Mary: I don't think so, baby.
Sheldon: Did you know that if gravity were slightly more powerful, the universe would collapse into a ball?
Mary: I did not.
Sheldon: Also, if gravity were slightly less powerful, the universe would fly apart and there would be no stars or planets.
Mary: Where you going with this, Sheldon?
Sheldon: It's just that gravity is precisely as strong as it needs to be. And if the ratio of the electromagnetic force to the strong force wasn't one percent, life wouldn't exist. What are the odds that would happen all by itself?
Mary: Why are you trying to convince me to believe in God? You don't believe in God.
Sheldon: I don't, but the precision of the universe at least makes it logical to conclude there's a creator.
Mary: Baby, I appreciate what you're trying to do, but logic is here. And my problem is here.
Sheldon: Well, there are 5 billion people on this planet and you're the perfect mom for me. What are the odds of that?

Meemaw: Look, you haven't even gotten to the worst part of it yet. They're gonna leave home. They're gonna move to another city.
Mary: Oh, Lord.
Meemaw: They're gonna tell you their loser boyfriend has knocked them up. Just to be clear, that would be you.
Mary: Sorry.
Meemaw: Turned my hair gray overnight.
Mary: I said sorry. Clearly, you're not in the mood to help.
Meemaw: Listen, it's hard being a parent, but if you do it right, they don't need you anymore.
Mary: Well, I don't like that. I get it, but I just don't like it.
Meemaw: Well, I'd point out, you'll always have your husband, but you want me to be "helpful".

Sheldon: Well, that's what I heard. And if Hawking doesn't let it stop him, then I can't let this cast stop me.
Missy: Great. Go back to sleep.
Sheldon: I will, and I'll do it all by myself. [sings] Soft kitty, warm kitty
Missy: Oh, my God.
Sheldon: Little ball of fur Happy kitty, sleepy kitty, purr Purr, purr.

George Jr.: "Have a great summer. Georgie". Normally I'd write, "Have a bitchin' summer", but I figured you wouldn't like that.
Sheldon: I wouldn't.
