A boy came home from school one day. His father asked him how his day was and the boy said, Well Dad, I looked stupid because I did not know the difference between potential and reality.
His dad says, Well son, go ask your mother if she would sleep with our next door neighbor for a million dollars.

He came back with a shocked look on his face and said, Dad, she said, Yes!.

OK son, now go and ask your sister the same question.

A few minutes later he came back, shocked again. Dad, she said, Yes! also!

His dad told him, There you go.

His son looked at him, puzzled. Dad I still dont understand.

Look son, POTENTIALLY we are multi-millionaires, but in REALITY we are dead broke and living with a couple of whores.
