Quote from : E.T. the Extra-Terrestrial Movie

Michael: Did you explain school to him?
Elliot: How do you explain school to higher intelligence?
Michael: Maybe he's not that smart. Maybe he's like a worker bee who only knows how to push buttons or something.
Elliot: [knowingly] He is too smart.
Michael: Okay, I just hope we don't wake up on Mars or something surrounded by millions of little squashy guys.
