This is a very funny joke, a boy at school was told by his classmate that most adults have at least one dark secret they are hiding and that it is very easy to blackmail them by just saying, “I know the whole truth”.
The boy decided to try the trick when he got home. As he is entered the house and greeted his mother, he said: “Mum, I know the whole truth.” His mother quickly hands him ₦1000 and says, “Please don’t tell your father.”
Very satisfied, the boy waits for his father to return, when his father got home, he greeted him and said: “Dad, I know the whole truth.” His father quickly gave him ₦4000 and says, “Please don’t say a word to your mother.”
Very pleased, the boy is on his way to school the next day, saw the mailman at their front door. The boy greets him by saying, “I know the whole truth.” The mailman drops the mail, opens his arms and says, “Then come and give your FATHER a big hug.”
