A man walks into a building. There's no power, so it's pitch black, making it hard for the man to see where he's going. The man approaches three doors. He goes through door number 2. He is then greeted by a masked man holding a knife and a flashlight. In a dark voice, he asks the man ''How would you like to die? The knife, or the electric chair?'' The man walked out alive.
How is this possible?
He chose the electric chair. There was no power in the building, so it didn't work.
