Sheldon: There's my favorite fire exit. Very well marked.
Mary: Nice.
Sheldon: Ooh. See that little step stool? They didn't have that before I got here.
Mary: Very impressive.
Sheldon: I know. And this is where I take my quantum field theory class. Those are my college classmates. I would tell you their names, but most of them won't make it to Christmas.

Sheldon: Missy and I broke a lot of rules the other night, and we've received no punishment.
George: [sighs] Buddy, it's been a rough week. We're just glad you're both safe.
Sheldon: But in the absence of a divine being, society's rules are what keeps a person's morality in check.
George: Well, there you go.
Sheldon: No, y-you're not following me. If actions have no repercussions, society breaks down, everything devolves into chaos.
George: You might be overthinking this.
Sheldon: I thought so, too. Then I thought about it, and I'm not.
George: Sheldon, you had one bad night. Just let it go.
Sheldon: But... I did something wrong and I got away with it. That's not okay.
George: Buddy...
Sheldon: Socrates maintained that the man who lies to himself has an enemy living within. He's not even a person. He's just a chaos of selfish desires wrapped in an animal hide.

Sheldon: Unbelievable. It's either cartoons or men in their underwear banging their heads together.
Ricky: You complain a lot.
Sheldon: Excuse me?
Ricky: Seriously, dude, you need to relax.
Sheldon: How can I relax? I'm being held captive in a bacterial playground.

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.

Dr. John Sturgis: I'm glad she's doing well. Tell her I say hi.
Mary: I will do that.
Dr. John Sturgis: Actually, no. Uh, tell her I said hello. "Hi" is a bit, uh, casual. Or wait. Greetings. Just say, uh, "Greetings from John."
Mary: You don't sound sure about that.
Dr. John Sturgis: No, I don't.

Mary: You wanted to see me, Pastor?
Pastor Jeff: Cop a squat. Uh, please, have a seat. I just wanted to thank you for all the work you've done preparing for the carnival.
Mary: Anything for the church.
Pastor Jeff: I'm so glad you said that. How would you feel if... we put Sheldon in the dunk tank?
Mary: What? No.
Peg: Aw.
Pastor Jeff: But imagine how much people would pay to dunk him. We'd raise so much money.
Peg: I'm in for $20, easy.
Mary: I'm not having people throw baseballs at my son.
Pastor Jeff: They throw them at a target. He's in a cage.
Mary: No!
Peg: Boo.
Pastor Jeff: Okay. I respect your decision.
Mary: Is that all?
Pastor Jeff: Yes.
Peg: Well, damn.
Pastor Jeff: [to the heavens] I do so much for you.

George: Does he really have to walk around with that?
Mary: He's fine. Leave him be.
Missy: You're just begging to get beat up.
Sheldon: I'm more concerned about the biggest bully of all: the Sun.
