Adult Sheldon: I've fought many digital battles in my life, but none are as memorable as this first one with my Meemaw. By handing me the controller, she was telling me she believed in me. That inside my small, fragile frame beat the heart of a hero.

Adult Sheldon: Since that night, I've battled orcs, zombies, Nazis, Nazi-zombies, a dinosaur in a go-kart, and played Van Halen's "Hot for Teacher" on a stringless, plastic guitar. But nothing would ever compare to that first quest with my meemaw. Although Leonard pulling a groin muscle doing Dance Dance Revolution was a close second.

Paige: I'm bored. Let's get out of here.
Sheldon: I can't. I told my dad I'd stay here until the end of the lecture.
Paige: Okay. Be a baby. I'm leaving.
Dr. Barrett: In our case, the math yields approximately 48,000 years.
Adult Sheldon: I was most certainly not a baby. If anyone was a baby, it was she, because people who call other people babies are the real babies.
Sheldon: [WHISPERING] Wait up.

Adult Sheldon: My mother's fears that no one would be saved that Halloween night were proven incorrect.
Mr. Lundy: As they kissed, she thought about the choices that led her to this moment.
Adult Sheldon: Mr. Lundy's scene about lust made a deep impact on my brother's date.
Mr. Lundy: Her youth was gone. She had traded her beauty for a few tawdry dollars, and now she had nothing left but shame and venereal disease.
Adult Sheldon: She asked to be saved by Jesus.
Veronica: [CRYING] I don't want to live like this anymore.
Mary: Oh, just repeat after me-
Adult Sheldon: And as it turns out, she was. She went on to live a life devoted to God, feeding the poor, even helping her sister start a literacy program for female prisoners. My brother, on the other hand, became a devout atheist after that night.
Mary: We got one!

All: Trick or treat.
Judy: Aren't y'all precious. And you look like a little Carl Sagan.
Adult Sheldon: Vindication, the sweetest candy of all.

Adult Sheldon: While my sister and I are twins, we've always been different. By the age of two, I was reading books. Missy was content to eat them. By five, I had a healthy appreciation for a well-organized work space. My sister, less so.

Adult Sheldon: The bond between twins is an incredibly close one, which is why I moved 1,500 miles to California the first chance I got.

Adult Sheldon: For most students, the weekend represented two days of fun, freedom, and in the case of my brother, a chance to ignore all forms of hygiene. But this wasn't a typical weekend, because this was the weekend I got to do my parents' taxes.
Sheldon: Howdy do, W-2.

George Sr.: Sheldon, all you got to do is be cool.
Adult Sheldon: "Be cool." He might as well have asked me to fly around the backyard.

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?

Adult Sheldon: If my mother's faith was the Starship Enterprise, over the next week, she achieved warp factor 9.

Mary: Thank you, Lord, for this little boy.
Sheldon: I knew I could fix it.
Mary: [LAUGHS] Maybe it was you and the Lord.
Adult Sheldon: I don't like sharing credit, but I knew in that moment it wasn't the appropriate time to say it.

Adult Sheldon: Not since sharing a uterus with my twin sister have I been so unhappy sitting next to someone.

Mary: Okay, look. You're right. I don't have many friends, so I was hoping to get to know Paige's mom. But if it makes you uncomfortable, then I will call her and cancel.
Sheldon: I'll think about it.
Mary: Thank you, baby.
Adult Sheldon: Guilt and jealousy in the same day. I slept hard that night.

Adult Sheldon: The thought of spending an afternoon with Paige seemed excruciating, but I wanted to make my mother happy. I was torn.
Dr. McCoy: The release of emotions, Mr. Spock, is what keeps us healthy Emotionally healthy, that is.
Adult Sheldon: Luckily, the wise words of Gene Roddenberry flatly delivered by Leonard Nimoy resolved my dilemma.
Mr. Spock: That may be, Doctor. However, I have noted that the healthy release of emotion is frequently very unhealthy.
Adult Sheldon: I realized if Mr. Spock could rise above his emotions while the fate of the Enterprise hung in the balance, certainly I could tolerate Paige for a few hours.

Adult Sheldon: : Vulcans use a technique called Kolinahr to suppress their emotions.
Mary: [OFF-SCREEN] Sheldon, they're here!
Adult Sheldon: Obviously, I wasn't a Vulcan. So I did the next best thing: took my feelings and shoved them down so far they may have been lost forever.

Paige: Sheldon! [She hugs him]
[flashback:] Dr. McCoy: The release of emotions, Mr. Spock, is what keeps us healthy.
Adult Sheldon: Dr. McCoy was an idiot.

Adult Sheldon: I started to think that Paige and I might have more in common than I thought.
Maybe my mother was right. I really did just need to get to know her better.
Paige: Checkmate! You lose. [CHUCKLES] Guess that makes me the smartest.
Adult Sheldon: I don't know if ten-year-old Spock ever flipped a chess board, but ten-year-old Sheldon sure did.

Adult Sheldon: And by some people, I mean everyone. While I may not be X-Men material I have always possessed unusually heightened senses.

Adult Sheldon: I also had extraordinary hearing. During dinner, I could tune out the cacophony of chewing, slurping, chewing, cutlery scraping against plates, chewing, and my father's heavy breathing as he wrestled with a ketchup bottle.
