Sheldon: Would you like to join me in my shenanigans?
Tam: No, thanks.
Sheldon: Aren't you concerned about being a maladjusted adult?
Tam: Nah. I'll just marry an American woman and hope she can fix me.

Mary: You smoke marijuana?

Tam: Hey, I've been looking all over for you. Do you know how popular we are?

Tam: Yeah. I put the word out I was helping you with the football stats. And since I'm Asian, they bought it.

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: And that's how I became the madcap prankster all my friends know and love.

Dr. John Sturgis: I don't think I can do this, Connie.
Meemaw: Of course you can. We're just getting started.
Dr. John Sturgis: No, it's too much information. I can't process it.
Meemaw: It was just a yellow light.
Dr. John Sturgis: Not just the light. There were other cars. There's pedestrians. There was a guy on a bicycle.
Meemaw: So?
Dr. John Sturgis: That's just too many random elements. The- The- The stimuli are overwhelming.
