Boy, "I want to be a policeman."
Teacher, "Why do you want to be a policeman?"
Boy, "Because you get the bad guys and you can do anything you want."
Teacher, "Being a policeman doesn't mean you can do anything you want and get away with it. You have to follow the same laws and rules as everyone else."
Boy, "What!? Well that's not what my momma said...My momma LIED to me!"
Well okay, we'll just leave it at that then!
