Adult Sheldon: I've always considered myself a collector of knowledge. My mind is like the warehouse at the end of Raiders of the Lost Ark. But instead of artifacts, it's just facts. [laughs] And now that I was a full-time college student, my collection was about to grow exponentially.
Professor Ericson: Welcome to the world of philosophy. Most college courses are about teaching you things that you don't know. Here, I am going to teach you that you don't even know what you think you know.
Sheldon: Oh, boy.

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: I stopped at the library today and picked up books on epistemology, Descartes's dream argument and the foundations of scientific logic. Do you know what she's going to do?
Meemaw: Rue the day?
Sheldon: The day, the night. If it's rue-able, she's going to rue it.

Missy: And at lunch, an eighth-grade boy said, and I quote, "I like Funyuns, too."
Mary: Wow.
Missy: I know.

Mary: Hey, Brenda.
Brenda Sparks: She didn't want you to walk her in?
Mary: No. How about Billy?
Brenda Sparks: Oh, I walked him in. Found his homeroom. Explained that "homeroom" is different than his room at home. Still not sure he gets it.
Mary: Tough day.
Brenda Sparks: Yeah.
Mary: You want to get some coffee?
Brenda Sparks: I was thinking vodka, but coffee will do.
