Paige: You didn't stay for the Q and A.
Sheldon: I had no Q's, and therefore, needed no A's.

Mary: Let's say grace.
Sheldon: Hang on, safety first. [puts mittens on]
George Jr.: When are you gonna get over that?
Sheldon: I would think recent events would make you value protection.
Mary: Enough.

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: It's great. Big fan.
Missy: Are you ever afraid you're wrong?
Sheldon: About religion? Never. About other things? Also never.

Sheldon: Paige? Why are you here?
Paige: The lecture.
Sheldon: Well, if you're looking to jump the line, I don't do cutsies.
Paige: No, I'm actually part of the lecture. Professor Patterson is my mentor at U.T.
Sheldon: Really? You're part of the quantum gravity team?
Paige: Yeah, it's actually really interesting. We've been examining all...
Sheldon: I know what it's about. It's why I've been waiting in line for three hours.
Paige: Wow, three hours to see me speak? I didn't know you were such a fan.

Sheldon: I can relate. A young lady brought chaos into my life as well today.
Missy: What happened?
Sheldon: Paige was visiting the university and got mad that I have college friends and she doesn't.
George Sr.: You're drunk, Sheldon has friends. This a crazy-ass dinner.

Paige: Your neighbors let you hang out with them?
Sheldon: I'm basically the social glue of our floor.
