I Know Your Secret

Two boys were talking and the one said to the other, 

"I found a really great way of getting adults to do 

anything I want." 

The other boy said, "How??"

The boy replied, "Just tell people you know their secret."

The boy jumps up and runs to his dad, "I know your secret!"

The dad replies, "Please don't tell your mom, heres $10."

The boy then runs to his mom, "I know your secret!"

The mom said, "Please don't tell your dad, here's $15."

The boy then decides to try it on the mailman, 

"I know your secret!"

The mailman opened his arms and said, "Finally! 

come and give your old man a hug!"
