Adult Sheldon: Eventually, Dr. Linkletter admitted we could use the help of Dr. Sturgis, and Team Science was back in action, scoring goals against Team Ignorance. Look at me, talking like a jock.
Dr. John Sturgis: Oh, I see you came around to my idea for distinguishing massive particles from axion particles.
Dr. Linkletter: Well, it did provide an excellent jumping-off point for me to crack the actual problem.
Dr. John Sturgis: Seems the actual problem is your inability to recognize a brilliant idea when it's handed to you.
Dr. Linkletter: Is that so, you pedantic little gremlin?
Dr. John Sturgis: How dare you! Well, it's all just simple...
Adult Sheldon: My father was right. They were bringing the best out of each other, like steel sharpening steel.

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.

Adult Sheldon: Visiting Tam's house for the first time was an emotional roller coaster.
For example, it's traditional in Vietnamese homes to have gruesome religious iconography near the entrance. I did not like that.
However, it's also customary to not wear shoes around the house for sanitary reasons. I did like that.
Interestingly, one of the main ingredients in Vietnamese cooking is an extremely pungent condiment known as fish sauce. I did not like that.
But before every meal, it's common for everyone to wash their hands and face. I did like that.
Forks are not customary in a Vietnamese household. I did not like that.
And instead of napkins, there was one towel for everyone to share at the table. Seriously, what are they thinking?

Adult Sheldon: I've fought many digital battles in my life, but none are as memorable as this first one with my Meemaw. By handing me the controller, she was telling me she believed in me. That inside my small, fragile frame beat the heart of a hero.

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.

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.

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.
