Shocking story

A small kid asked his wealthy self-made friend (that is also a small kid) the secret behind him making hundreds of dollars everytime he speaks to an adult that he knows, and his buddy replied "the secret is telling the adult I know everything, they will simply tell you to keep your mouth shur and hand you a ton of money". So the little kid went home to his mother and said "mom, I know everything!" So his mother told him to shut up and not tell anyone, and handed him a thousand dollars. The kid then tried the same thing with his dad, and his dad told him to keep his mouth shut and not tell anyone, and handed him 2 thousand dollars. The kid got excited and went outside to try it on other adults he knew in the neighborhood. First person he sees is the mailman, the kid says "Hello Mr.Mailman! I know everything!". Then the mail man said "REALLY?? COME GIVE DADDY A HUG!!". The end.
