Sheldon: [on the phone] And since we're both on spring break, I thought you might like to go with me.
President Hagemeyer: Sheldon, I am the president of the university.
Sheldon: You're right. I should've asked you first. So is that a "yes"?
President Hagemeyer: No!

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.

Ms. Hutchins: I don't know.
Mary: Trust me, the men are gonna be lining up.
Ms. Hutchins: Well, they haven't been so far, and I've been basically giving it away.
Mary: That's your business really.

Sheldon: Mom, I know what I want to do for spring break. What happened to your face?
Mr. Lundy: Told you, people take notice.
Mary: This is for my new job.
Sheldon: Is your new job fighting Batman? Because you look like The Joker.

Nathan: Hey, you made it. [Star Trek salute]
Sheldon: It would have been illogical not to.
Nathan: [deep voice] Well, you're going to have a blast.
Sheldon: I know this is un-Spock-like, but I can't stop smiling.
Mr. Givens: [climbs aboard] [British accent] There you are, dear sir. Let's get this pusillanimous bucket of nuts and bolts on the road. [applause and cheering] We have a comic-con to get to!
Sheldon: Mr. Givens?
Mr. Givens: Oh, the pain.
