Sheldon: OK, well, it was pleasant seeing you, other than that business with my testicles. [Puts his hand out for her to shake]
Missy: Come on Shelly. [Gives him a hug, which Sheldon does as well.]
Missy: I want you to know I'm very proud of you.
Sheldon: Really?
Missy: Yep. I'm always bragging to my friends about my brother, the Rocket Scientist.
[Sheldon looks in disbelief.]
Sheldon: You tell people I'm a Rocket Scientist?!
Missy: Well yeah.
Sheldon: I'm a theoretical physicist.
Missy: What's the difference?
Sheldon: What's the difference?!
Missy: Goodbye, Shelly.
Sheldon: My God! Why don't you just tell them I'm a toll taker at the Golden Gate Bridge! Rocket Scientist, how humiliating!
