Mary: And please look after Sheldon and I as we travel to Germany.
Sheldon: "Sheldon and me".
Mary: [sighs] God doesn't care about grammar.
Sheldon: You're not gonna be on a ten-hour flight with God.
Georgie: I bet it's gonna feel longer than ten.

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.

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.

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.

Missy: One question.
George: Yes?
Missy: What's 0600?

Mandy: Okay, we got diapers, wipes, change of clothes, bottles, binkies, bibs.
Georgie: And we got your boobs, so we're set on food.
Mandy: Okay, please don't bring my boobs up when we're at my parents' house.
Georgie: Well, what if it comes up naturally?
Mandy: It won't.

Sheldon: When we get there, you'll be looking for "international departures".
George: Ah, well, thanks for letting me know that Germany's in a different country.
Sheldon: Is he joking? I'd like to believe he's joking.
Mary: He's joking, Sheldon.
Sheldon: He's a football coach. I don't know what he knows.
