Bob: Ten dollars? I'll give you five.
Sheldon: Sir, that's a Lionel MPC-era O Gauge that I've had since I was six. You're lucky it's only ten.
Bob: Fine. Ten.
Sheldon: Uh, uh, I meant $20.
Bob: T-The tag says ten.
Sheldon: And now it's a thousand. Give that back. Have a nice day.

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: Hello, Pastor Jeff.
Pastor Jeff: Sheldon, George, good news. I told the congregation about your exciting opportunity in Germany, and boy, were they thrilled to help. [laughs] I've never seen the collection plate so full.
Sheldon: Well, thank you. Are you seeing this? I am beloved.
Pastor Jeff: Sure.

Sheldon: I brought you some snacks. For Mom, a Bavarian-style pretzel. And for Dad, four Lone Star beers poured into a pitcher to approximate a stein.
George: What do you want?
Sheldon: For starters, a danke wouldn't kill you.
Mary: A what?
Sheldon: It's "thank you" in German. Uh, so, if you were thinking of thanking, then you'd be denken of danken. You're awfully quiet. I assume you're denken.
Mary: W-Where are you going with all this?
Sheldon: If I play my cards right, Germany.

Mary: Well, we're gonna have to talk to Dr. Sturgis before we make any decisions.
George: We're- We're not making any promises.
Mary: Mm-hmm.
George: This is not a yes.
Sheldon: But it's also not a nein, which German for "no", as opposed to the number nine, which is neun.
