Amy: This has been your lifelong dream. And you may not get another chance. I don't want to be the reason that you don't win a Nobel.
Sheldon: You're the only reason I deserve one.

Bernadette: Why don't you want to work with me? I know I can be tough, but that's just 'cause I'm surrounded by useless idiots.

Penny: Uh, if I didn't know then, I'm not going to magically know now.
