Sheldon: Aah. No skateboarding in the hallway. Aah! This childishness cannot be allowed to continue.

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.

Sheldon: [on the phone] Hello, Mom. It's your son, Sheldon.
Mary: Hello, my son, Sheldon.
Sheldon: I have an 8:00 a.m. class tomorrow, and I was wondering if I could spend the night in my dorm.
Mary: That's fine.
Sheldon: Now before you answer, hear me out. I have a list of reasons why this is a good idea. Number one...
Mary: Sheldon, I know that you're safe there. It's fine.
Sheldon: That's reason number four. Please don't skip ahead.
Mary: Honey, I trust you. Just go to bed at a reasonable hour and call if you need anything. Otherwise, I'll see you tomorrow.
Sheldon: Okay. Number one: I'm not...
Mary: Goodbye, Sheldon. [hangs up]
Sheldon: Who hangs up on a list?

Sheldon: I've compiled a list of reasons why I should be appointed the dormitory R.A. Number one...
President Hagemeyer: Fine. You're the R.A.
Sheldon: Okay. "Number one: I love rules... creating them, following them, and most fun of all, enforcing them."
President Hagemeyer: You're the R.A., Sheldon.
Sheldon: Excellent. "Number two... punishment for rule infractions must be both fair and merciless."

Meemaw: Do you see any unoccupied machines here?
Dale: No.
Meemaw: Exactly. We are at capacity. It's time to expand.
Dale: Where?
Meemaw: The video store right behind that wall just lost its lease.
Dale: Aw, heck. I was gonna pick up the new John Candy.
Meemaw: Well, as my partner in this enterprise, you can get that new John Candy for free.
Dale: So you're gonna buy a video store?
Meemaw: Video store in the front, video poker in the back.
