Adult Sheldon: My father didn't always get the credit he deserved. The advice he gave me actually worked out pretty well. Of course, I never told him.
George: Talked to Billy.
Missy: Why would you do that?
George: No, it was good.
Missy: Stay out of my life.
Adult Sheldon: He may not have been the world's greatest dad. But maybe we weren't the world's greatest kids.

Adult Sheldon: I didn't realize until years later that my father was only asking questions about lightning and thunder to cheer me up. In fact, he would often pretend to be dumb just to make me feel better.

Pastor Jeff: Before our final prayer, would anyone else like to say a few words?
Mary: Missy? [Missy shakes her head] Shelly?
[Sheldon stands up and walks up to the microphone]
Sheldon: I've been thinking a lot about the last moments I had with my dad. It was morning, and he was leaving for work. He said, "See y'all later." And I said nothing. I regret that. I could have said "bye" or asked him for a ride. Or told him that I loved him. But I didn't. I barely noticed he left. So many times that I didn't notice my father. I hope he knew how much I loved him.
Adult Sheldon: I wish I could tell you I said all those things. But I didn't.
Mary: Shelly? [Sheldon shakes his head] [Mary shakes her head to Pastor Jeff]
Pastor Jeff: Let's bow our heads in prayer.
All: Our Father, who is in heaven, hallowed be Your name...
Adult Sheldon: For a long time, I focused on my father's shortcomings. Now that I'm his age and have kids of my own, I realize he was just a person doing the best he could, and he did a lot. I didn't say it at his funeral, but I can say it now. I loved my father. I will miss him forever.

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.

Georgie: I'm not here to work. I'm here with the answers to all your problems.
Meemaw: And what is that?
Georgie: How to get your back room up and running again.
Meemaw: I'm listening.
Georgie: I was thinking about Chuck E. Cheese.
Meemaw: Oh, God.
Georgie: Hear me out. Your payouts were in cash. That's illegal. When you play games at Chuck E. Cheese, you win tickets. Those tickets are traded for prizes. That's legal. You just need to do the same thing. People play your machines. Now the credits they win get exchanged for stuffed animals. Then you buy those stuffed animals back for cash. No laws broken, and you're back in business.

Adult Sheldon: You probably think of quantum physics as a white-knuckle rush of adrenaline, like the Peter Pan ride at Disneyland. But the reality can be a little less exciting, especially when you're stuck. [clock ticking] [lights humming] [water bubbles]
Dr. Linkletter: We'll get this.
Sheldon: Perhaps a set of fresh eyes could be helpful.
Dr. Linkletter: If you're going to suggest Dr. Sturgis, I should remind you we have a complicated history.
[flashback:]
Dr. John Sturgis: And your graviton research is mediocre at best!
Dr. Linkletter: You're not qualified to judge my work.
Dr. John Sturgis: All right, that's it. [they shove each other]
[present:]
Sheldon: We'll get this.

Sheldon: Dr. Linkletter and I are stuck on a science problem. I know Dr. Sturgis could help, but I'm hesitant to suggest that because I know they have a professional rivalry.
George: Well, the way I see it, y'all are on Team Science, right?
Sheldon: I suppose.
George: And people on the same team don't have to get along to work together.
Sheldon: Like you and Mom.
George: No. A quarterback and his receivers. He doesn't throw it to the guy he likes best. He throws it to the one that's open.
Billy Sparks: So smart.
Sheldon: So, I should ask Dr. Sturgis what he thinks about the dark matter being a Bose condensate?
George: Do you want Team Science to win?
Sheldon: Thank you. This has been helpful. [exits]
Billy Sparks: What's a Bose condensate?
George: I'll tell you at halftime.
