Mary: Baby, you need to eat something.
Sheldon: But it looks like I can change the definitions of electric and magnetic fields and rotate the magnetic charge away mathematically to zero.
Mary: Maybe some fried okra would help.
Sheldon: Richard Feynman didn't develop quantum electrodynamics by filling up on fried okra.
Mary: Well, maybe that's because his mama didn't love him as much as I love you.
Adult Sheldon: Richard Feynman was Jewish. His mother didn't give him fried okra.

Adult Sheldon: You never know where scientific inspiration will strike. For Newton, it was under an apple tree. For Archimedes, it was sitting in a bathtub. For me, on this particular day, it had a "sweaty people eating meat" kind of vibe.

Sheldon: State troopers. I wonder what they want.
Adult Sheldon: It turns out they wanted me. Fun fact, this was one of seven times I was brought home by law enforcement once, on the back of a horse.

Adult Sheldon: The world had stopped making sense. A grown-up had lied to me, my meemaw and I were at odds, I was in trouble with my parents. I had to find a way to restore balance.

Adult Sheldon: Teachers have always been impressed by me. And my new college professor was no exception. You'd think it was my once-in-a-generation intellect. But it was more than that. There was my wicked sense of humor.
Dr. Linkletter: ...explained by maximizing entropy. Yes, Sheldon?
Sheldon: Entropy. It isn't what it used to be.
Adult Sheldon: Plus, when things got heavy, I was always ready with a fun fact to lighten the mood.
Sheldon: Fun fact: Did you know that the ancient incas stored bureaucratic records on knotted strings called "quipu"? Q-U-I-P-U. Quipu.
Adult Sheldon: Whatever the reason, I was clearly his favorite student.
Dr. Linkletter: Connie, what a treat it is to see you.
Adult Sheldon: Look at him smile. He couldn't get enough of me.

Mary: I'm reading this book about mental problems, and I'm worried it sounds like Sheldon.
George Sr.: Well, stop reading the book.
Mary: Shelly and Dr. Sturgis have a lot in common, and look what happened.
George Sr.: What, you mean like how he went to-
Adult Sheldon: As a society, we've made strides in how we discuss psychological issues. 30 years ago in East Texas, let's just say we hadn't.
George Sr.: cuckoo, cuckoo. [blubbers]

Adult Sheldon: Some people are just natural-born worriers. My mother, for example, could whip herself into a frenzy even if I were sitting on my bed doing nothing.

Adult Sheldon: A primary feature of quarks is that they're always bonded together, but in that moment, I felt like a neutrino, destined to be alone forever.
[Montage of young Leonard, Penny, Raj, Howard, Bernadette and Amy at that moment]
Adult Sheldon: Thankfully, I was wrong.

Adult Sheldon: A few times a year, there was a dedicated day where my school was closed.
This allowed the teachers to catch up on their administrative duties. While I was normally against a break from learning, I did applaud the Medford faculty's commitment to our education.

Adult Sheldon: Living in a small Texas town, a few things are guaranteed: Someone nearby will have chickens. Everyone will know your business. But on the brighter side, in a small Texas town, people take care of each other.

Adult Sheldon: Before I became Dr. Sheldon Cooper, I was President Sheldon Cooper. And I don't mind telling you, they both look pretty darn good on business cards. One of my first responsibilities as class president was delivering the morning announcements.

Adult Sheldon: Emboldened by my father's pep talk, I began working on my speech. I aspired to walk in the footsteps of history's greatest orators: Socrates, Winston Churchill, and, last but not least, Professor Proton.

Adult Sheldon: Another hurdle in my political career was glossophobia: fear of public speaking.
I've been known to experience dry mouth, perspiration, heart palpitations, and fainting. A similar response to what I experience around unleashed dogs.

Adult Sheldon: Not all science is created equal. There's physics, the undisputed king of science.
There's chemistry. It's no physics, but it's not a bad way to pass a rainy afternoon. And then there's biology, the squishiest of the sciences.

Adult Sheldon: The prospect of advancing to the next stage of academia had me feeling giddy.
And, on top of that, I got to pack a suitcase, which is like playing Tetris but with underwear.

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

Adult Sheldon: Over the next few days, I continued to play the violin in an effort to replicate the mental prowess of Einstein. I was asked to confine my practice to the garage by my father, mother, sister and brother. Meemaw was fine with me practicing in the house, but why would she care? She doesn't live with us.

Adult Sheldon: I'd like to tell you a story about a time I was right. Now, I'm sure you're thinking, "But, Sheldon, you're never wrong." And you'd be right. But it's worth taking a closer look at this particular incident. Because it began with a loaf of bread, and ended with me and my family almost being kicked out of the United States of America.

Adult Sheldon: Dr. Sturgis was a wise man. It was a learning opportunity. And when the day comes that I'm wrong, I fully plan to admit it.

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.
