At school Little Johnny was told
by a classmate that most adults are hiding at least one dark
secret, and that his makes it very easy to blackmail them by
saying, "I know the whole truth." Little Johnny decides
to go home and try it out. He goes home, and as he is greeted by
his mother he says,
"I know the whole truth."
His mother quickly hands him $20 and says, "Just don't tell
your father."
Quite pleased, the boy waits for his father to get home from
work, and greets him with, "I know the whole truth."
The father promptly hands him $40 and says, "Please don't
say a word to your mother."
Very pleased, the boy is on his way to school the next day when
he sees the mailman at his front door. The boy greets him by
saying,
"I know the whole truth."
The mailman immediately drops the mail, opens his arms, and says,
"Then come give your real father a big hug."
