Adult Sheldon: Like Batman's utility belt, my briefcase was equipped for any emergency. I don't know if the Bat-pants had a zipper, but if they did, I could fix it.
Sheldon: Oh, dear.

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?

Billy Sparks: Who's Melissa?
Missy: Me.
Billy Sparks: Then who's Missy?
Missy: "Missy" is short for "Melissa." Like how "Billy" is short for "William."
Billy Sparks: I don't understand.
Missy: You know how your real name is William?
Billy Sparks: I'm Billy.
Sheldon: No, we call you Billy, but your real name is William.
Billy Sparks: But my underpants say "Billy" in them. Mom, is my name William?
Brenda Sparks: [sighs] Yeah.
Billy Sparks: Then whose underpants am I wearing?

Sheldon: I may not look it, but I'm the future of physics, so just move on.

Pastor Jeff: Two months! Two months till this baby comes! There's so much I thought I was gonna do in my life.
George Sr.: I'm sure you've done plenty.
Pastor Jeff: Nothing cool. Look at you. You played football and rode a motorcycle.
George Sr.: Well, you save people's souls. That's neat, right?
Pastor Jeff: Oh, it's neat as neat can be, but you know that's not what I'm talking about.
George Sr.: [sighs] Look, being a dad doesn't mean your life is over. It just means it's different. Instead of playing football, I get to coach it now. I mean, high school football. Not college like I'd hoped. I-Instead of a motorcycle, I drive a truck. To work every single day. To pay the bills. [sighs] Oh. Endless bills. What happened to my life?
Pastor Jeff: Orange wedge?
