Adult Sheldon: Scientific rivalries are a fact of life. When two competing scientists work on a project, it can devolve into an intellectual boxing match. Over the years, there's been a few classic heavyweight bouts. Newton and Leibniz. [bell ringing] Tesla and Edison. And in a lesser-known but equally brutal bout...

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?

Dr. Linkletter: I cannot work with that creepy little know-it-all one more day.

Dr. Linkletter: Sturgis. Well, both, but mostly Sturgis.

Dr. John Sturgis: He's not interested in anyone else's input.
President Hagemeyer: I-I'm sorry, Sheldon or Linkletter?
Dr. John Sturgis: Linkletter.
President Hagemeyer: Ah, got it. Continue.

Dr. John Sturgis: I was brought in to help but Dr. Linkletter doesn't value my input.
President Hagemeyer: Oh, I hear you. That must be tough.
[cut to:]
Dr. Linkletter: Ever since he was brought back, he contradicts everything I say.
President Hagemeyer: I hear you. That must be tough.

Sheldon: There was a time when their arguing brought out the best in them, but now it's just hindering our work.
President Hagemeyer: I hear you. That must be tough.

Dr. John Sturgis: The free-streaming length of the axion is too long. It'll erase the fluctuations.
Dr. Linkletter: You're completely forgetting that it is nonrelativistic dark matter.
Dr. John Sturgis: You'll never have the resolution to see microkelvin features.
Dr. Linkletter: I think your brain is as smooth as the top of your head.
Dr. John Sturgis: Low blow, Grant.
Sheldon: He's right, gentlemen, let's keep it to science.
Dr. John Sturgis: You'll never have the resolution to see microkelvin features.
