Mary: Thank you, Lord, for this little boy.
Sheldon: I knew I could fix it.
Mary: [LAUGHS] Maybe it was you and the Lord.
Adult Sheldon: I don't like sharing credit, but I knew in that moment it wasn't the appropriate time to say it.

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?

Mary: Sheldon, faith means believing in something you can't know for sure is real. And right now, I am struggling with that.
Sheldon: So you don't believe in God anymore?
Mary: That isn't something for you to worry about. I need to figure this out myself.
Sheldon: Can I help? Maybe I could provide a fresh perspective.
Mary: I don't think so, baby.
Sheldon: Did you know that if gravity were slightly more powerful, the universe would collapse into a ball?
Mary: I did not.
Sheldon: Also, if gravity were slightly less powerful, the universe would fly apart and there would be no stars or planets.
Mary: Where you going with this, Sheldon?
Sheldon: It's just that gravity is precisely as strong as it needs to be. And if the ratio of the electromagnetic force to the strong force wasn't one percent, life wouldn't exist. What are the odds that would happen all by itself?
Mary: Why are you trying to convince me to believe in God? You don't believe in God.
Sheldon: I don't, but the precision of the universe at least makes it logical to conclude there's a creator.
Mary: Baby, I appreciate what you're trying to do, but logic is here. And my problem is here.
Sheldon: Well, there are 5 billion people on this planet and you're the perfect mom for me. What are the odds of that?

George Jr.: Would you feel more confident if I told you I already know how to drive?
George Sr.: Video games don't count.
George Jr.: I'll have you know I've driven Meemaw's car. I also drove your truck one night while you were sleeping.
George Sr.: Are you crazy?!
George Jr.: I parked it and everything, you had no idea.
George Sr.: Okay, let let me get this straight. You're trying to prove to me that you're a responsible person by admitting you stole my truck.
George Jr.: I said I was responsible, never said I was smart.

Sheldon: And then I said octopus aliens didn't need to become Christian because they're not affected by original sin.
Missy: You should've been there; Pastor Jeff almost started crying.
George Sr.: Oh, now I'm sorry I missed it.
Mary: That's your fault for having a hangover.
George Sr.: Or it's God's fault for putting Sunday morning after Saturday night.
