A young boy went up to his father and asked: "What is the difference
between potentially and realistically?"

The father pondered for a while, then answered: "Go ask your mother if she would sleep with Robert Redford for a million dollars. Also, ask your sister if she would sleep with Brad Pitt for a million dollars. Come back and tell me what you have learned."

So the boy went to his mother and asked: "Mum, would you sleep with Robert Redford for a million dollars?"
The mother replied: "Of course I would. I wouldn't pass up an
opportunity like that."

The boy then went to his sister and said: "Would you sleep with Brad Pitt for a million dollars?"
The girl replied: "Oh gosh!! I would just love to do that! I would have to be nuts to pass up that opportunity!!".

The boy then thought about it for two or three days and went back to his dad. His father asked him: "Did you find out the difference between potentially and realistically?"

The boy replied, "Yes, potentially we're sitting on two million dollars,
but realistically we're living with two slappers."
