A boy went up to his father and said, "Your secret is out now dad. It's no use hiding it."

His father's face went pale. He gave the boy $100 and told him to keep quiet about it.

Happy that the trick worked, he then went to his mother and said, "Your secret is out now mom. It's no use hiding it." Just like his dad, his mom was shocked too. She gave the boy $200 and told him to keep quiet about it.

Excited, the boy thought who should he try the trick on next when he saw the postman outside his house. He approached the postman and said, "Your secret is out now mister. It's no use hiding it." The postman, completely shocked, hugged the boy and said, "I am glad you finally know it son."
