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: 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 Sr.: Talked to Billy.
Missy: Why would you do that?
George Sr.: 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: 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: 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 Sr.: Talked to Billy.
Missy: Why would you do that?
George Sr.: 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.

George Jr.: I'm not here to work. I'm here with the answers to all your problems.
Meemaw: And what is that?
George Jr.: How to get your back room up and running again.
Meemaw: I'm listening.
George Jr.: I was thinking about Chuck E. Cheese.
Meemaw: Oh, God.
George Jr.: 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.

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 Sr.: Well, the way I see it, y'all are on Team Science, right?
Sheldon: I suppose.
George Sr.: And people on the same team don't have to get along to work together.
Sheldon: Like you and Mom.
George Sr.: 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 Sr.: Do you want Team Science to win?
Sheldon: Thank you. This has been helpful. [exits]
Billy Sparks: What's a Bose condensate?
George Sr.: I'll tell you at halftime.
