Mary: Should you really be reading in the car, baby?
Sheldon: I'll be fine.
Mary: You sure? You're not the one who'll have to clean up the oatmeal back there.
Sheldon: I said I'll be fine. And it's the blueberries you should be worried about.
Mary: Well, you're in a mood.
Sheldon: Maybe because there was so much bickering going on at home that I couldn't study.
Mary: Oh, I'm sorry if our family problems are getting in the way of your schoolwork.
Sheldon: I accept your apology. [vomits]
Mary: Oh...
Sheldon: Yep, blueberries.

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: 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.

Sheldon: If we're switching religions, may I recommend Judaism.
Mary: Why?
Sheldon: Both William Shatner and Leonard Nimoy are Jewish.
George Sr.: So?
Sheldon: Isn't that enough?

Adult Sheldon: I was struggling to focus and needed help. Luckily, there was someone on campus I could always count on to lend a friendly ear. A second mom, if you will.
President Hagemeyer: What now?
Sheldon: You said if I ever had a problem, I could come to you and you'd fix it.
President Hagemeyer: When did I say that?
Sheldon: September 13th, 1991. You had just eaten a poppyseed bagel and had one stuck in your teeth.
President Hagemeyer: I'll take your word for it.
Sheldon: It was right here. How did it not make you crazy? It made me crazy.
President Hagemeyer: What do you want?
Sheldon: My family's falling apart.
President Hagemeyer: Oh, I'm sorry to hear that. Uh... what do you want me to do?
Sheldon: Fix it.
