Pastor Jeff: Please be seated. A Pharisee once asked Jesus what the greatest commandment was, and do you know what he said? [Sheldon raises his hand] Sheldon, it's a rhetorical question.

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.

Missy: What's it like to not believe in God?

Sheldon: Seems unlikely; my mother's on Vulcan.
Billy Sparks: My mom is on Valium.

Dr. John Sturgis: So if Einstein's analysis of time is correct, the future's already happened, but we'll discuss that in more detail next week.
Sheldon: Or perhaps we already have.
Dr. John Sturgis: Exactly. [laughs]
Meemaw: Good one.
