A young boy went up to his father and asked him: "Dad, what is the difference between potentially and realistically?"
The father thought for a moment, then answered: "Go ask your mother if she would sleep with Brad Pitt for a million dollars. Then ask your sister if she would sleep with Brad Pitt for a million dollars, and then, ask your brother if he'd sleep with Brad Pitt for a million dollars. Come back and tell me what you learn from that."
So the boy went to his mother and asked: "Would you sleep with Brad Pitt for a million dollars?"
The mother replied: "Of course I would! We could really use that money to fix up the house and send you kids to a great University!"
The boy then went to his sister and asked: "Would you sleep with Brad Pitt for a million dollars?"
The girl replied: "Oh my God! I LOVE Brad Pitt! I would sleep with him in a heartbeat, are you nuts?"
The boy then went to his brother and asked: "Would you sleep with Brad Pitt for a million dollars?"
"Of course," the brother replied. "Do you know how much a million bucks would buy?"
The boy pondered the answers for a few days and then went back to his dad. His father asked him: "Did you find out the difference between potentially and realistically?"
The boy replied: "Yes. Potentially, you and I are sitting on three million dollars, but realistically, we're living with two hookers and a homo."
