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.

Adult Sheldon: I didn't realize until years later that my father was only asking questions about lightning and thunder to cheer me up. In fact, he would often pretend to be dumb just to make me feel better.

Adult Sheldon: My father didn't always get the credit he deserved. The advice he gave me actually worked out pretty well. Of course, I never told him.
George Sr.: Talked to Billy.
Missy: Why would you do that?
George Sr.: No, it was good.
Missy: Stay out of my life.
Adult Sheldon: He may not have been the world's greatest dad. But maybe we weren't the world's greatest kids.

Adult Sheldon: Visiting Tam's house for the first time was an emotional roller coaster.
For example, it's traditional in Vietnamese homes to have gruesome religious iconography near the entrance. I did not like that.
However, it's also customary to not wear shoes around the house for sanitary reasons. I did like that.
Interestingly, one of the main ingredients in Vietnamese cooking is an extremely pungent condiment known as fish sauce. I did not like that.
But before every meal, it's common for everyone to wash their hands and face. I did like that.
Forks are not customary in a Vietnamese household. I did not like that.
And instead of napkins, there was one towel for everyone to share at the table. Seriously, what are they thinking?

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.
