Captain: [v.o.] Ladies and gentlemen, this is your captain speaking. We're expecting a smooth flight to Los Angeles. Before we take off, please direct your attention to the flight attendants as they review some important safety procedures.
Sheldon: "Safety procedures"? Oh, baby.

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.

Pastor Jeff: Come on up here, Sheldon. Let's hear what you got.
Sheldon: I've spent the last week studying what people believe, and I've come to a conclusion.
Pastor Jeff: And what's that?
Sheldon: I'm starting my own religion.
Pastor Jeff: I'm sorry, what?
Sheldon: I'm calling it Mathology. It's based on a universal binary system.
Pastor Jeff: That's terrific, Sheldon, but this is a Baptist Sunday school.
Sheldon: I know, I'm here to convert everybody. Any takers?
Pastor Jeff: Okay. Let's go have a talk with your mom.
Sheldon: The only sin in Mathology is being stupid.

Mary: Too bad. We are going.
Sheldon: Class is starting tomorrow. I'm not going anywhere.
Mary: Sheldon, do not argue with me. You are going home.
Sheldon: Mom, the people of Germany are obsessed with rules and devoid of humor. I am home.

Sheldon: Dad, the university offered to pay for us to go to California! They're even putting us up in a hotel.
George: 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.

George: Mr. Spock! He flies around all the time in that spaceship. He's not afraid, is he?
Sheldon: I'm not Mr. Spock.
George: No, but-but I've seen you pretend to be him. Could you do that right now? You be Spock, I'll be Kirk.
Sheldon: Maybe.
George: Okay, Mr. Spock. Your first order is to return to your seat.
Sheldon: Aye, Captain.

Sheldon: Dad, good news. Airline tickets to California are more affordable than you think.
George: 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.
