Missy: Interesting.
Sheldon: What does it say? No, don't tell me. Okay, tell me. No, don't!
Missy: Sheldon, if I tell you but you never look at it, then you didn't break the law, right?
[later:]
Janice: [answers phone] Law offices of Morris, Morris & Yorn. Janice speaking.
Sheldon: [on the phone] Hello. I'd like to speak to either Morris, Morris or Yorn.
Janice: May I ask what it is in regard to?
Sheldon: Well, I was slicing a hot dog...

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.

Mary: So, George is mad at me, and Sheldon is mad at me, and... honestly, I'm mad at me, too.
Brenda Sparks: Will you please give yourself a break? All that you do for that family, I am surprised you didn't crack years ago.
Mary: How do you handle it all?
Brenda Sparks: I'm sitting in a chicken coop drinking a wine cooler at 11:00 a.m.... clearly, I don't.

George: What do you want, Sheldon?
Sheldon: I want to know why no one told me about this recruitment letter from Caltech.
George: Let me see that.
Mr. Givens: All right, let's get me drunk.
Sheldon: Hi, Mr. Givens.
Mr. Givens: Aw, come on!

[on the "Why Sheldon Cooper Should Go to College" tape:]
Ms. Ingram: Honestly... teaching Sheldon is the hardest thing I've ever had to do. And I don't say that because he can be a pain. I say that because he's so intelligent, I had to study every night just to keep up. I'm gonna miss him.
