Paige: I'm bored. Let's get out of here.
Sheldon: I can't. I told my dad I'd stay here until the end of the lecture.
Paige: Okay. Be a baby. I'm leaving.
Dr. Barrett: In our case, the math yields approximately 48,000 years.
Adult Sheldon: I was most certainly not a baby. If anyone was a baby, it was she, because people who call other people babies are the real babies.
Sheldon: [WHISPERING] Wait up.

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. John Sturgis: Connie, I need to apologize.
Meemaw: Oh, that's okay. Don't worry about it.
Dr. John Sturgis: No, I am worrying about it. I didn't realize that with you and I being in a relationship, me wearing your dead husband's clothes would be emotionally challenging for you.
Meemaw: All right, apology accepted.

Mary: Mom, can you make the salad?
Meemaw: Sure.
George Sr.: Hey, don't put in any of those little tomatoes.
Meemaw: Hey, I don't tell you how to impersonate a lump of clay. You don't tell me how to make a salad.

Sheldon: Dad, do you believe that fossils are millions of years old?
George Sr.: I guess. Why?
Sheldon: Well, Mom believes the world was only created 6,000 years ago.
George Sr.: Yeah. So?
Sheldon: Are these differences a sticking point in your marriage?
George Sr.: Not at all.
Sheldon: Why?
George Sr.: Simple. We never talk about it.
Sheldon: So you just avoid discussing topics you don't agree on?
George Sr.: At all costs.
