Adult Sheldon: I had suffered some setbacks. But just as Edison had forged ahead on electric lighting without the help of Tesla, I was going to make it through orientation without the help of my mommy, even if she did make boo-boos stop hurting. While I had found inspiration courtesy of Thomas Edison, it was soon replaced with anger at Whitcomb L. Judson, inventor of the zipper.
Sheldon: [scoffs] Oh, come on.

Adult Sheldon: Like Batman's utility belt, my briefcase was equipped for any emergency. I don't know if the Bat-pants had a zipper, but if they did, I could fix it.
Sheldon: Oh, dear.

Adult Sheldon: The good name of Lady Science had been besmirched and it was up to me to defend her honor. I had a lot of ground to cover in one night. Thankfully, 11 years of my family's incessant yammering had given me an extraordinary ability to focus.

Adult Sheldon: It was past my bedtime, but who could sleep with a page-turner like Meditations on First Philosophy by René Descartes? Descartes was more than just a philosopher. He was also the mathematician who invented the Cartesian plane. If you've ever enjoyed that X squared plus Y squared equals K is a circle, you can say merci beaucoup to Monsieur Descartes.

Adult Sheldon: Traditionalism is the philosophy that the best way of life is a return to the past.
Georgie: What are you doing?
Sheldon: [shaking a jar] Making my own butter, like in olden times.
Georgie: That's stupid.
Adult Sheldon: My arms are still sore.

President Hagemeyer: And this, of course, is our physics prodigy, Sheldon Cooper.
Justin: A great pleasure. [offers hand]
Adult Sheldon: I had an obligation to fulfill. So I closed my eyes and thought of science. [Sheldon shakes Justin's hand] Just like on my honeymoon.

Adult Sheldon: It turned out Gary did appreciate my honesty. The school got a generous donation.
President Hagemeyer: My, my, my. That is a lot of zeroes.
Adult Sheldon: My father got Oilers tickets from President Hagemeyer.
George: 50-yard line and free parking? Hoo-mama.
Adult Sheldon: And I got a brand-new, state-of-the-art antistatic lab chair.
Sheldon: It works.

Mary: What's it say?
George: Okay. Not so bad. We owe four dollars and 22 cents.
Sheldon: What?
Mary: That could've been worse.
George: Yeah, tell me about it.
Sheldon: Let me see that.
George: I'm gonna wash up for dinner.
Sheldon: You realize they're wrong. My return was flawless.
George: I-It's four dollars. Forget it.
Sheldon: But they're saying I made a mistake.
Mary: You also got us a nice refund. You did a great job.
Adult Sheldon: I appreciated my mother's love, but what a boy really craves is the unconditional approval of a government agency.

Adult Sheldon: I've never been good at sharing. I had to share a womb...
Missy: [over ultrasound video] Ow.
Sheldon: [over ultrasound video] Ow.
["Rico Suave" by Gerardo playing over headphones]
Adult Sheldon: ...a bedroom...
Missy: ♪ Rico...♪
Adult Sheldon: Even my train room had Georgie's sweaty weight bench in it.
Georgie: Come on, George. One more. Feel the burn, big boy. Feel the burn.
Adult Sheldon: But when it came to academics, the spotlight was all mine.
President Hagemeyer: Sheldon, having you here has been a real boon to this university.
Adult Sheldon: [spotlight shines on Sheldon] I did love basking in its glow.
President Hagemeyer: So we could really use your help in raising the school's profile even higher.
Sheldon: Of course. My intellect is at your service.
President Hagemeyer: Excellent. There is another young physics prodigy we want you to help us recruit. Her name is Paige Swanson. [electricity crackles]

Adult Sheldon: Classical physics can predict a lot about the world. For example, it can tell us what happens when one pool ball knocks into another. But when multiple balls careen in different directions, we've entered the wild and woolly world of nonlinear dynamics. And you don't need me to tell you that it's impossible to predict what will happen next. Actually, based on the state of our educational system, you probably do. Now imagine those are people. Even a brilliant young ball who graduated high school at 11 can be caught in the maelstrom. Aah! Our first collision was set in motion when Pastor Jeff and Robin had their baby.

Adult Sheldon: In physics, potential energy is a fascinating topic. Objects like springs store energy when they're coiled, waiting to unleash their full potential and soar to the heavens. Would you look at me go! Even in toy form, I'm shooting for the stars. While the potential energy of an object can be measured in absolutes, human potential remains more elusive. Sometimes, people seem to have all the potential in the world, but for some reason stay stuck to the ground.

Adult Sheldon: I've always had a curious affinity for Laundromats. Perhaps it's the rows of mechanical devices dedicated to a cleaner world. Or maybe it's the hypnotic rotation of spinning clothes on their sudsy journey to a fluffy, stain-free future. Mmm, look at 'em. Where was I? Oh, yes. Laundromats. My meemaw also loved them, but for an entirely different reason.
Meemaw: Banana, banana... Whoo! [laughs]
Adult Sheldon: Personally, I don't care for bananas. It's a texture thing.

Adult Sheldon: In astronomy, a syzygy is a rare event when three or more celestial bodies line up.
You may also know it as the stars aligning, which was probably coined by someone who couldn't spell "syzygy." If you want to win Scrabble, remember this bad boy. My father's idea of the stars aligning was having the house completely to himself. I was at school, Missy was at a friend's, Georgie was working, and my mother was on her way to a church retreat.
[elsewhere:]
Mary: [sings] There was a God who had a son, and Jesus was his name-o ?
Pastor Jeff: [sings] J-E-S-U-S
Mary: [sings] J-E-S-U-S
Pastor Jeff: J-E-S-U-S
Mary: And Jesus was his name-o. [honks horn]
Adult Sheldon: For my father, it was sweet, Southern syzygy. S-Y-Z-Y-G-Y. Syzygy. [doorbell rings]
George: [sighs] Balls.

Adult Sheldon: You know it's bleak when even a trip to RadioShack couldn't lift my spirits.
Announcer: Professor Proton will be right back after these messages.
[A recruitment commercial plays for the U.S. army]
Sheldon: Of course.
Adult Sheldon: I realized Professor Boucher was pushing me to be the best me I could be. You'd think the person who could teach me to be the best me I could be was me, but it was Professor Boucher, after the Army taught him to be the best he that he could be. Now it was up to me to help us be the best "we" we could be.
