Georgie: You just need to introduce me to her.
Sheldon: Why?
Georgie: I want to be her friend.
Sheldon: Well, you better take a number. She's friends with a lot of boys around here.

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.

Tam: You see a large red button. What do you do?
Billy Sparks: I press it.
Tam: The floor opens up and you plunge into a 60-foot pit.
Billy Sparks: I fly out. Up, up, and away!
Sheldon: Again, you're not Superman in this game; you're Superman for Halloween.
Tam: Which isn't till next week.
Billy Sparks: So I'm in a pit.
Tam: You're in a pit.
Billy Sparks: Then I blast my way out with my super breath! [BLOWING]
Sheldon: Just let him do it.

Mary: It's awful. It makes sin seem like a good thing.
George: Well, that's the problem, isn't it? I mean, if sin didn't seem like a good thing, nobody would do it.
Mary: George, please, I'm in no mood.
George: Hey. Wrath. That's one of the seven sins, right?
Mary: Pastor Jeff gave me this project because he knew I'd be best at it. Now Gene Lundy is taking over.
George: Oh, look, pride. And envy. Don't stop. Four sins to go. I'm guessing lust ain't happening tonight.

Billy Sparks: Did you know Superman has a dog? His name is Krypto. He plays fetch in space.
