The Truth

At school Little Johnny was told by a classmate 
that most adults are hiding at least one dark
secret, and that this makes it very easy to blackmail
them by saying, "I know the whole truth."

Little Johnny decided to go home and try it
out. He went home, and as he was greeted by his
mother he said, "I know the whole truth." His
mother quickly handed him $20 and said, "Just
don't tell your father."

Quite pleased, the boy waited for his father
to get home from work, and greeted him with,
"I know the whole truth." Johnny's father promptly 
handed him $50 and said, "Please don't say a
word to your mother!"

Very pleased, the boy was on his way to school
the next day when he saw the mailman at his front
door. Little Johnny greeted him by saying, "I
know the whole truth."

The mailman immediately dropped the mail, opened
his arms saying, "Then come give your daddy a
big hug."
