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 plays 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.

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.

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: : As we sat in silence, I had a horrible realization. For the first time in my life, I didn't look forward to doing my homework.

Sheldon: So one-fourth of the 12 pieces of pie is?
Missy: Three?
Sheldon: Yes. And one-third of the 12 pieces is?
Missy: Four?
Sheldon: Yes. Now how much is one-third of the pie plus one-fourth of the pie?
Missy: Well, three plus four is seven, but there's 12 pieces, so seven-twelve-iths.
Sheldon: It's twelfths. And yes.
Missy: I did it.
Adult Sheldon: Actually, I did it. In less than ten minutes, I taught fractions to a monkey.

George: Okay, here we go, Sheldon. One "precision astronomical refractor telescope."
Sheldon: Wow. Thanks, Dad.
Adult Sheldon: For the next few weeks, my guilt-ridden father continued to lavish me with gifts. Then the football playoffs started and that was that.

Adult Sheldon: News of my friendship with Tommy had apparently spread. So much so, the student body was finally treating me with the respect I deserved, even when Tommy wasn't around. This must be how Carl Sagan felt, walking through the halls of PBS.

Adult Sheldon: Like Superman in a phone booth, I was no stranger to undressing in my gym locker. But not today. Thanks to Tommy, I was invincible.

Adult Sheldon: Conventional wisdom tells us that when one stands up to a bully, the bully will inevitably back down and respect you for your courage. My experience suggests otherwise. When Jason finally caught me, he had the good sense not to commit assault and battery. This did not, however, prevent him from imprisoning me in his locker. That was a very long night. Very long.

Adult Sheldon: It should come as no surprise that the very first grade I ever received was a "super-duper." Granted it was for counting spots on a ladybug, but still, I nailed it. Even as the difficulty of assignments grew, I maintained the same level of excellence. In every class, in every subject, I was perfect. Which is why this day hit me like a ton of bricks.

Adult Sheldon: Once again, I brought my mother so much joy she was moved to tears. I don't know how I do it.
