Adult Sheldon: In the world of collecting, I'm what's known as a completist. For example, I own every gauge of model train from the mighty "G," to the tiny "T." Look at how cute it is, I just want to eat it up. However, the downside of being a completist is when something's missing, it's like an itch you can't scratch, even if you own a complete set of Justice League back scratchers... which I do. In this case that itch was the comic book issue Doom Patrol and Suicide Squad Special #1.

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: 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?

Adult Sheldon: I've fought many digital battles in my life, but none are as memorable as this first one with my Meemaw. By handing me the controller, she was telling me she believed in me. That inside my small, fragile frame beat the heart of a hero.

Sheldon: Too bad there's not a comic book database so I could search through it and find what I'm looking for.
Dr. Linkletter: Well, CERN has something similar. You can search a database of scientific papers.
Sheldon: But there's no database for comic books.
Dr. Linkletter: You should make one. Somewhere else.
Sheldon: Mmm, sounds like a lot of work.
Dr. Linkletter: Or does it sound like a lot of fun? Go find out.
Sheldon: Do you want to do it with me?
Dr. Linkletter: Only if you share credit, and my name comes first.
Sheldon: Never mind. [exits]
Dr. Linkletter: I knew that would work.

Sheldon: So, as you can see on the chart on page 34, the amount of time spent searching for grants would be cut by 80%. Do you see what this could do for the scientific community?
President Hagemeyer: Yes. [gasps] We could charge an access fee to every university on the planet, and I can retire on a yacht in the Bahamas.
Sheldon: You're missing the point.
President Hagemeyer: Yeah, yeah, yeah. Uh, good for science. I love it.

Georgie: Were you mad at Mom for getting pregnant?
Meemaw: Oh, yeah.
Georgie: Did you stop talking to her?
Meemaw: Hell no, I wanted her to hear how pissed off I was. But all that being mad at her just was a waste of time.
Georgie: What made you come around?
Meemaw: I guess you showing up.
Georgie: I do have a natural charm, don't I?
Meemaw: You did, and then you learned to talk.
