Sheldon: How would you feel about joining me in the groundbreaking search for exoplanets that could support life?
Dr. Prakash: I'd love it. How would you feel about joining me in finding subatomic particles that move backwards in time?
Sheldon: You mean tachyons?
Dr. Prakash: Yes.
Sheldon: That's nonsense. Let's get started on my thing.

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: I need telescope time to search for exoplanets, and Dr. Linkletter and Dr. Sturgis have denied my request.
President Hagemeyer: Why?
Sheldon: They said that kind of research would expose both me and the university to criticism.
President Hagemeyer: [stifled laugh] Well, that's outrageous.
Sheldon: So, you'll give me access?
President Hagemeyer: Gosh, no. I want to, but... I'm just the president. [chuckles] Use of the telescope has to be approved by a... science advisor.
Sheldon: Is that true?
President Hagemeyer: Does it sound true?
Sheldon: I suppose it does.
President Hagemeyer: Then I suppose it is.
Sheldon: Why did I even come to you?
President Hagemeyer: [gasps] Remember that next time.

Sheldon: Dr. Linkletter, I need to talk to you.
Dr. Linkletter: Are we in my office?
Sheldon: No.
Dr. Linkletter: Then these are not my office hours.
Sheldon: Are you using my love of schedules against me?
Dr. Linkletter: [chuckles] Oh, yes.
Sheldon: Well done.

Sheldon: President Hagemeyer, we have a problem.
President Hagemeyer: What now, Sheldon? The Yoo-hoos in the vending machine aren't cold enough?
Sheldon: Actually, they aren't, but we'll table that for later.
