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.

Meemaw: Hello?
Dr. John Sturgis: Did you know that word "hello" wasn't used as a greeting - until the invention of the telephone?
Meemaw: Hi, John.
Dr. John Sturgis: To end a phone call, it was suggested to say, "That is all."
Meemaw: Is that all, John?
Dr. John Sturgis: No, I wanted to invite you to dinner tomorrow night.
Meemaw: Great. Where we going?
Dr. John Sturgis: I can't tell you that. It's a surprise.
Meemaw: You want to give me a clue so I'll know how to dress?
Dr. John Sturgis: Well, dress as if you were going to a Mexican restaurant.
Meemaw: Oh, we're going to Puerta Roja.
Dr. John Sturgis: I can't tell you that, it would ruin the surprise.
Meemaw: John, you do realize that I'll be the one driving us there.
Dr. John Sturgis: Fine, we're going to Puerta Roja, but everything else is a surprise. That is all!

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: Did you know that there's a type of vanilla flavoring derived from the anal glands of the North American beaver?
Meemaw: That seems like a fact you could have shared before we started eating.
Dr. John Sturgis: It isn't used very often. I understand it's difficult to, uh, milk the little sacs.
Meemaw: Cool. Okay, new topic.

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.

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.

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.
