Little Johnny was told by his friends that adults have a deep dark secret and can be easily manipulated.

Johnny decides to test it. He comes home, goes up to his mother and says, "Mom, I know everything." Mom shushes him and gives him $10.

"Just don't tell Dad" she says.

Hey, it's working thinks Little Johnny.

An hour later, Dad comes home from work. Johnny goes up to him and says: "Dad, I know everything."

Dad gives Johnny $100. "Don't tell Mom" he says.

Just then, the mailman knocks on the door. Johnny opens it and says. "I know everything, Mister."

The mailman drops all his mail, his eyes tear up and he says:

"Well then Johnny, come give Daddy a hug."
