Meemaw: Yes?
Sheldon: How's it going?
Meemaw: It's Sheldon again.
Sheldon: What do you mean "again"?
Meemaw: Speak.
Sheldon: I recently read an article about a superconducting supercollider that might be built in Texas.
Meemaw: What about it?
Sheldon: Well, I thought if there was a lull in your dinner conversation, you might casually drop it as an icebreaker.
Meemaw: Our dinner conversation is going just fine.
Sheldon: Well, now you have it in your back pocket. Carry on.

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.

Adult Sheldon: I would go on to draw up such contracts throughout my life. With roommates. With my wife. Even with my own children.

Mary: He's just excited that Meemaw's dating a man he looks up to.
Georgie: I wish she could date Tony Danza that'd be cool.
George: What is it with you and Tony Danza?
Georgie: Well, the show doesn't come out and say it, but I'm pretty sure he's the boss.
Missy: I think the blonde lady's the boss.
Georgie: Angela? Who's the oddball now?

Mary: I know you've had a number of gentleman callers, but I've never heard you speak like this before.
Meemaw: "Gentleman callers"?
George: And we wonder where Sheldon gets it.
