Pastor Rob: Gentlemen. How are we tonight?
Billy Sparks: [whispers] Be cool.
Pastor Rob: Y'all wouldn't be planning on throwing any water balloons at the girls later?
Billy Sparks: No, sir.
[Pastor Rob picks up Billy's backpack and removes a water balloon]
Pastor Rob: Nice try.
Billy Sparks: How did he know?
Sheldon: Maybe God told him.

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.

Billy Sparks: I've seen this before. They're big now, but they're gonna get small.
Missy: Yeah. It's called Honey, I Shrunk the Kids.
Billy Sparks: [whispers] If you get scared, I'm here.
Missy: Terrific.

Sheldon: Wil Wheaton plays Wesley Crusher. He's a child prodigy who's very young to be on the bridge of a Galaxy-class starship.
Missy: Okay.
Sheldon: But he's so intelligent that most people come to rely on him.
Missy: Okay.
Sheldon: Sounds kind of familiar, huh?
Missy: Okay.

George Jr.: You know one of the best things about working here? I always smell like dryer sheets.
Mandy: Is that a good thing?
George Jr.: Compared to how I used to smell, yeah.
