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 don't understand."
" Look son, POTENTIALLY we are multi-millionaires, but in REALITY we are dead broke and living with a couple of whores."
