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.

Dr. John Sturgis: See, this is why we're great together. You teach me about social etiquette, and I teach you about beaver anuses.
Meemaw: [CHUCKLES] It is magical.
Dr. John Sturgis: Did you know "ani" is also acceptable as the plural of "anus"?
Meemaw: And the magic continues.

Dr. John Sturgis: Hello, my little vicuña.
Meemaw: [chuckles] Well, hello to you, too. And more importantly, what is a vicuña?
Dr. John Sturgis: Only what I feel is the cutest camelid on the planet.
Meemaw: Well, I suppose I could ask you what a camelid is, but you're just gonna say more words that I don't know.

Meemaw: John?
Dr. John Sturgis: Hello.
Meemaw: What- What're you doing?
Dr. John Sturgis: I was doing tai chi and then I realized that I was continually being bombarded by subatomic particles and it behooves me, perhaps, to pay slightly closer attention to them. Maybe "chi" is the ancient Chinese word for the subatomic universe.
Meemaw: You're scaring me, John.
Dr. John Sturgis: Well, there's nothing to be scared of. Tomorrow, somebody will win the Nobel Prize about these particles not me. But I'm experiencing them firsthand [LAUGHS] which could be better.
Meemaw: Why don't you come down and experience them on the floor?
Dr. John Sturgis: I think I just felt a neutrino. [LAUGHING] You know, neutrinos are interesting. They never bond with anything, they're always alone. I think that one went right through my pants.
Meemaw: All right, why don't we go downstairs, and I'll fix us both a nice cup of hot tea and you can tell me all about it. Please?
Dr. John Sturgis: Okay. It was my dream to win the Nobel, and I'm not going to. I bet Sheldon will.
Meemaw: That'll be something.
Dr. John Sturgis: Yeah.

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.

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.

Adult Sheldon: Over the next several days, my social experiment was providing clear-cut data about the benefits of being well-liked.
Matt: Hey, Sheldon. Heard you like these.
Sheldon: Thank you. It's the best watery chocolate milk on the market.
Matt: Thank you for letting me use your room.
Adult Sheldon: I suppose it was like the old saying, "I scratch your back, you scratch mine," which I actually have issues with. Why is your back itchy? A rash? Chicken pox? Scabies? Scratch your own back.
