Sam: Wait, you have a single?
Sheldon: Uh-huh.
Sam: And you don't even sleep here?
Sheldon: Well, sometimes I take naps, but that mattress is lumpy, lumpy.
Sam: I live with two other girls in a room this size.
Sheldon: You should've complained to President Hagemeyer. She was very accommodating.
Sam: Wait, there are two closets?
Sheldon: That's a bathroom.
Sam: Are you kidding me? I share one with, like, 30 other people.
Sheldon: That sounds yucky.
Sam: It is, Sheldon. It is very yucky. However yucky you think it is, it is yuckier.
Sheldon: Well, you're welcome to use mine. Just squat over the seat, don't sit.

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.

Sam: This is so unfair. You get so much more than every other student.
Sheldon: Fair isn't everyone getting the same thing. Fair is everyone getting what they deserve.
Sam: Sheldon, that arrogant attitude is why no one sits with you in class or lunch or ever.
Sheldon: Well, I like to think that they're maintaining a respectful distance out of deference to my intellect.
Sam: No. That's not what they're doing. They're avoiding you because you're an entitled brat who thinks that you're better than everybody else.
Sheldon: So, I should just pretend I'm less intelligent than I am?
Sam: You should realize that there are more important things in life than how smart you are.
Sheldon: Well, I'm also cute as a button, but it seems shallow to say it. [an exasperated Sam walks away] You could say it.

Dr. John Sturgis: You see, humans have evolved as social animals, so your feeling hurt might be a deep evolutionary desire to cooperate with others to ensure your survival.
Sheldon: So, you're saying it makes sociobiological sense to want other people to like me?
Dr. John Sturgis: Yes, and you may even get benefits from it. It's like on that show you enjoy, Star Track.
Sheldon: Trek.
Dr. John Sturgis: Right. Captain Kirk can't do it all by himself. He needs Doctor Spock.
Sheldon: Mister.
Dr. John Sturgis: Right. And Mister McCoy.
Sheldon: Doctor.
Dr. John Sturgis: Right.
Sheldon: Well, technically, they were his subordinate officers, but Kirk did always deal with them in a friendly manner, so I take your point.
Dr. John Sturgis: Good man.
Sheldon: I suppose I could treat it like an experiment. Run an analysis of the benefits of having people like me.
Dr. John Sturgis: That sounds like an idea the Captain, the Doctor, or the Mister would be proud of.
Sheldon: Excellent.
Dr. John Sturgis: You know, you'd think a smart fella like Spock would have a doctorate.
Sheldon: Actually, Spock rejected an offer from the Vulcan Science Academy in order to attend Starfleet.
Dr. John Sturgis: Huh. Not the choice I would have made, but I'm happy for him.

President Hagemeyer: Here we are.
Sheldon: [chuckles] What is this?
President Hagemeyer: A dorm room, and it's all yours. You can study, take naps, do whatever you want.
Sheldon: No one's living here?
President Hagemeyer: Well, we had an Indian exchange student, but he developed a taste for barbecue, so his parents made him go home.
Sheldon: Well, thank you for this.
President Hagemeyer: You're welcome.
Sheldon: It's like I always say, never underestimate the power of complaining.
Adult Sheldon: I've been testing that theory for decades, still works like gangbusters.
