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: 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?

George Jr.: See? They ain't allowed to dance, either.
Missy: It's like I'm watching my life.
George Jr.: That's how I feel when I'm watching Top Gun.

George Sr.: Come on, Sheldon, think of it as a free dinner.
Sheldon: I'm a kid. All my dinners are free.

Dale: Now, what do you think young people talk about on their dates?
Meemaw: I don't know. But my knee's telling me it's gonna rain this weekend.
