Paige: You know, I read that adults who had a stunted childhood often become social misfits and weirdos.
Sheldon: You didn't read that, you're making it up like your goat story.
Paige: Psychology Magazine, February issue, 1988.
Sheldon: Well, um, that doesn't make it true.
Paige: Guess you'll find out when you're an adult.
Sheldon: I guess I will.
Adult Sheldon: Well, we know how this story ends. I grew up to become a well-adjusted and charming fellow. But at that moment in time, she had me worried.

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: Talked to Billy.
Missy: Why would you do that?
George: 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: 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: And that's how I became the madcap prankster all my friends know and love.

Georgie: All right, I'm just gonna come out and ask it: what the heck is a colleague?

Paige: Hi, Sheldon.
Sheldon: Hello.
Paige: What are you doing?
Sheldon: Chemistry homework for extra credit.
Paige: Cute, I did that last year.
