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.

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: Ignoring things that irritate me isn't my strong suit. Obsessively fixating on them, now that's what gets me out of bed in the morning.

Adult Sheldon: Even while sleeping, my quest to save the princess continued, which was quite a departure from my usual dreams, such as determining the coolest prime number Which, by the way, is 73.

Meemaw: I'm Sheldon Cooper's grandmother and, uh, I need to take him out of school today.
Diane: Sure. What's the reason?
Meemaw: His Aunt Emelda's not doing well, and has asked to see him 'fore she goes.
Diane: Oh, I am so sorry. Does she want to see his older brother also?
Meemaw: Nah. She doesn't like him as much.

Herschel Sparks: I appreciate that, but you got to know there's an upside to this.
George: And that would be?
Herschel Sparks: Your son has got a special gift.
George: A gift? We are talking about Georgie, right?
Herschel Sparks: Yeah. I mean, first off, the kid really knows his way around an engine, which is all well and good. But when it comes to fixing tires, I swear, I've never seen anything like him.
George: Tires? How do you mean?
Herschel Sparks: George, I've been patching flats for 25 years. You know, slap some soapy water on them, look for the air bubble. But your son, he doesn't need any tricks. He knows where the puncture holes are.
George: He knows?
Herschel Sparks: He knows. He's got a sixth sense for tire damage. I mean, you got to see him in action. It'll give you chills.
George: You know, now that you say it, whenever we had a leaky football, he knew exactly where the hole was.
Herschel Sparks: I am telling you, your boy's got a future in the tire business. Goodyear, Firestone, somebody's gonna scoop him up first round.
