Darren: Any chance you play Dungeons and Dragons?
Sheldon: And how. I once created a campaign set in 1940s London where Alan Turing was a character, and I had the mathematicians be magic users with theorems instead of spells. The intelligence officers were clerics...
Darren: "Yes" works. We're playing tonight and we're down a magic user. You in?
Sheldon: When are you playing?
Darren: We start at 7:00. We'll go till whenever.
Sheldon: My mom didn't let me stay past 6:00 yesterday. She'll never let me stay till "whenever."
Darren: Bummer.
Sheldon: Mm. You could play at my house.
Darren: No.
Sheldon: Bummer. I've never said that before. Did it sound cool?
Darren: No.
Sheldon: Bummer.

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.

Mary: What is going on? Sheldon, are you okay?
Sheldon: My stomach hurts.
Darren: He's gonna throw up.
Mary: Did you give him beer? Did they give you beer?!
[Mary follows Sheldon, Darren and Oscar into the dorm room]
Sheldon: Just root beer.
Mary: It's gonna be okay, baby. [Sheldon throws up] Oh. Why is it so colorful?
Sheldon: Too many... [gags] Skittles. [retches]

George Sr.: Where's the coffee?
George Jr.: I finished it.
George Sr.: When you finish a pot, you're supposed to make more.
Mary: Oh, is that the rule?
George Sr.: It is for him. Why are you reading my paper?
George Jr.: Well, pardon me for keeping up on events of the day.
George Sr.: Tomorrow's headline: Father Strangles Son.
George Jr.: Good luck. My horoscope says "things are looking up."

Adult Sheldon: Grown-ups and the elderly had always liked me, and now I had won over undergrads. Like a beloved board game, I'm fun for ages nine to 90.
