Mary: Let's say grace. Bless us, Lord, for the food we are about to receive, and bless the hands that prepared it. Amen.
All: Amen.
Sheldon: I told Dr. Linkletter about Georgie.
George Jr.: Why'd y'all tell Sheldon?
Missy: They didn't. I figured it out.
George Jr.: Great. Now everyone knows.
Mary: Not everyone.
Sheldon: Just us and Dr. Linkletter.

Principal Petersen: Our next young speaker needs no introduction, but that didn't stop him from writing one and making me read it. [laughter] "Fun fact." [audience groans, murmurs] I hear you. "The word 'valedictorian' is from the Latin 'valedicere,' meaning 'to say farewell.' It is primarily used in the United States, Canada, the Philippines and Armenia." Maybe that fact's more fun in Armenia. Please welcome your valedictorian, Sheldon Cooper.
Mary: Yay, Shelly!
Sheldon: Hello. I'm not very comfortable speaking in front of crowds. But there's a technique to reduce stage fright by focusing on one person in the audience and delivering your speech just to them. That's what I'll be doing today. If it weren't for this person, I wouldn't be here right now. They've taught me a lot, and it's by their example that I found the courage to move forward into this new and exciting chapter of my life. Missy... ...this is for you. Change can be scary, but I know we're going to be fine... ...because like you said, "It's okay to be scared. We just have to do it anyway." So if any of my fellow graduates are nervous about the future, know that you're not alone. I suggest you all try to be as brave as my twin sister. That's my plan. Missy, I wish I could give you advice about middle school, but I was so smart, I skipped it. If you make it to high school, we'll talk. Thank you. [applause]

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.

Missy: [groans] Mom and Dad are still really upset.
Sheldon: With good reason. She's awfully old to be having a baby.
Missy: Is it really dangerous?
Sheldon: Not with modern science, but back in pioneer times, we'd be burying her down by the crick.
Missy: I'm just saying they're cranky enough, so don't be a pain in the ass.
Sheldon: I'm always on my best behavior. You're the hormonal firecracker around here.
Missy: Sheldon.
Sheldon: And thar she blows. Moby Dick. It's a book.

George Sr.: Where the hell's my travel mug?
Mary: I think Georgie took it, dear.
George Sr.: That son of a gun.
Mary: Missy, your father's gonna take you to school today.
Missy: Thanks, Daddy. I hope it's not too much trouble.
George Sr.: [smiles] No trouble at all, my little angel. [Mary smiles at Missy, too]
Sheldon: [to Missy] Why'd you say they're cranky? They're fine.

Meemaw: What's up?
Missy: Why won't Mom and Dad tell us what's going on?
Meemaw: Well, there might be several reasons for that, but right off the top of my head, I'd say none of your damn business.
Sheldon: Mom's having a baby, and that's none of our business?
Meemaw: [chuckles] Is that what you think's going on?
Missy: Isn't it?
Meemaw: No.
Sheldon: Then what's going on?
Meemaw: None of your damn business.
