Sheldon: Stop! You're not fighting Tommy, you're fighting me.
Tommy: Oh, boy.
Sheldon: Unless you want to shake hands and we all laugh about this over a glass of milk.
Jason: I think I'd rather kick both your asses.
Sheldon: I was afraid you'd say that. Are you familiar with the story of David and Goliath from the Bible?
Jason: Yeah.
Sheldon: That's too bad. I had a nice speech prepared. I'll say it anyway. You may have the size advantage, but like David and his sling, I also possess an air-based weapon. So I'll give you one more chance. Are you willing to step down?
Jason: I'll tell you what: you take the first shot, then it's my turn.
Sheldon: Very well. Three, two, one.
Jason: Ow! Son of a bitch!
Sheldon: I'm going to run.

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: Look at this, my mother left me a note. "You can do better. Mom." Not "Love, Mom," not "XO, Mom," just "Mom."

Sheldon: Good news, I just spoke to Tommy Clarkson.
Georgie: What? Are you crazy?
Sheldon: Nope, Mom had me tested.

Sheldon: Excuse me, sir. When you're done urinating, I'd like to ask you some questions about social dynamics, intimidation, threats, et cetera. Finish up, no hurry.
