Sheldon: I'm wasting too much time sleeping at night. In fact, where's the coffee machine? Perhaps it is time I start chasing the caffeine dragon.
Dr. Linkletter: Sheldon, listen to us.
Sheldon: Why should I? You let this happen to me. You failed as my mentors. [Linkletter starts erasing Sheldon's equations from the whiteboard] What are you doing?!
Dr. Linkletter: You're still the student, this is still my office, and it's time for you to leave. [Sheldon turns to Dr. Sturgis]
Dr. John Sturgis: I'm afraid he's right. [Sheldon exits]

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: I'm waitin'.
George: For what?
Mary: The "I told you so." 'Cause I coddled Sheldon and apparently ruined his life.
George: Oh. I'm not gonna say that. I mean, you did coddle him and I did tell ya... All right, I told you so.
Mary: Thanks for not sayin' it.

Sheldon: Hold on, should I be trying to beef up my grad school applications?
Dr. John Sturgis: The competition is fierce. It takes a lot to stand out.
Sheldon: You're my advisors, why didn't you advise me of this?
[flashback:]
Dr. John Sturgis: Sheldon, if I could offer you some advice...
Sheldon: No thank you.
[flashback:]
Dr. Linkletter: Sheldon, I have a recommendation for you.
Sheldon: I have one for you. Trim your nose hair.
[present:]
Dr. Linkletter: Do you remember that?
Sheldon: I do. It looked like a spider was living up there.

Sheldon: [on the phone] Yes, is this the Columbia summer science honors program? Excellent. My name is Sheldon Cooper, perhaps you've heard of me. Well, now you have. Anyways, it's recently come to my attention that you could be an important step in my career advancement. So, good news, I'm available. Yes, I understand I've missed the deadline, but I'm sure you can make an exception. [emotional] But I'm Sheldon Cooper.
