Adult Sheldon: For many college kids, waiting in line for concert tickets is a rite of passage, and I was no different. Except, instead of rock and roll music, my concert was a lecture on black hole topology. Instead of a stage dive, I would dive into knowledge. Instead of guitar-shredding solos, I would witness universe-shredding hypotheses. And instead of a charismatic front man dazzling the audience, there would be... well, actually, the exact same thing.

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?

Sheldon: Paige? Why are you here?
Paige: The lecture.
Sheldon: Well, if you're looking to jump the line, I don't do cutsies.
Paige: No, I'm actually part of the lecture. Professor Patterson is my mentor at U.T.
Sheldon: Really? You're part of the quantum gravity team?
Paige: Yeah, it's actually really interesting. We've been examining all...
Sheldon: I know what it's about. It's why I've been waiting in line for three hours.
Paige: Wow, three hours to see me speak? I didn't know you were such a fan.

Missy: Meemaw picked me up in her new car.
Meemaw: We drove with the top down. A truck driver honked at us. [chuckles]
Missy: It was awesome.
Meemaw: See? Missy loves my car. I don't know what Dale's problem is.
Missy: You're too good for him anyway.
Mary: Should she really be hearing about all this?
Missy: Mom, she just got dumped. It's what you do. Ooh, is any of his stuff at your house? Let's set it on fire.
Mary: Don't you have homework?
Missy: My grandma's hurting. She needs me.
Mary: Go.

Paige: Your neighbors let you hang out with them?
Sheldon: I'm basically the social glue of our floor.
