Adult Sheldon: Meemaw liked to teach me things that kept me awake at night.

Adult Sheldon: For a brief moment, I was filled with the healing power of faith. Then the next day, we all got violently ill from Billy Sparks' eggs, and I was over it.

Adult Sheldon: Fun fact the first time I almost died was at the age of nine. The murder weapon? A Jimmy Dean sausage.

Adult Sheldon: Somehow, my parents didn't find out about me partying heartily. But I did pay a price for burning the candle at both ends. I made a mistake on a math test. In my exhaustion, I did all the calculations in my head, and, like a common zoo animal, forgot to show my work.

Adult Sheldon: Extricating myself from this situation was not going to be easy. My father was counting on me, Meemaw was counting on me, the school was counting on me. After much thought, I decided to employ the one strategic maneuver I knew I could count on. I tattled.

Adult Sheldon: With my research complete and my ulcer on the mend, all that was left to do was send my work to NASA and wait to become America's scientific sweetheart.

Adult Sheldon: I don't know if other supervillains started their careers by getting out of P.E., but that's where I began.

Adult Sheldon: Emboldened by my faux hernia, I started taking books out of the library without getting the cards stamped.

Tam: You didn't check out those books.
Sheldon: I know.
Adult Sheldon: Before you judge me too harshly, I always brought them back on time. I was a rule-breaker, not a lunatic.

Adult Sheldon: And finally, I had to apologize to my meemaw, who was an unfortunate victim of my sister's treasure hunt.

Tam: So you leave tomorrow?
Sheldon: Yes.
Tam: Dallas.
Sheldon: Yes.
Tam: Cool.
Adult Sheldon: It was touching to watch Tam bravely fight back tears.
Tam: Have you ever thought about making the trains go clockwise?
Sheldon: No.
Tam:
Adult Sheldon: You should. Brave, brave Tam.

Adult Sheldon: I never heard from One and Zero again. Although, I was once visited by Nine when I had chickenpox. He was a lot less funny than he thought he was.

Adult Sheldon: The home computer I had long coveted was finally in my possession, but it was also destroying my home. Thankfully, it came pre-loaded with a program to help solve personal problems.

Adult Sheldon: In 1989 the Milton Bradley Company had dozens of board games on the market, but only one where you were the doctor. Operation came complete with a red light-up nose, 13 plastic body parts for players to remove and, most importantly, one pair of genuine tweezers. My sister performed a medical procedure using a children's board game, while I bravely sat very still. I guess you could say there were two heroes that day.

Adult Sheldon: Mr. Lundy gave a compelling speech. The audience did deserve to see what they came for, an eager boy bravely taking on the role of Little Orphan Annie. And in that respect, they were not disappointed.

Adult Sheldon: The basic premise of the book was that phobias were overcome by taking incremental steps toward confronting the phobia in question.
In my case, that started with watching a TV show that was adored by children around the world, but for me, was the stuff of nightmares. [Scooby Doo playing on TV]

Mary: Hey, who are you calling?
Sheldon: Dr. Sturgis.
Mary: Why?
Sheldon: I saw Meemaw get in a car with Mr. Rosenbloom.
Mary: No.... [dives across the room towards Sheldon]
Adult Sheldon: I don't know if it really happened this way, but to my nine-year-old mind, my mother was flying.

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

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.
