A young boy went up to his father and asked, "What's the difference between potentially and realistically?" The father ponders for a moment, then answered "Go ask your mother if she would sleep with Robert Redford for a million pounds and also ask your sister if she would sleep with Brad Pitt for a million pounds, then come back and tell me what you learned." So the boy went to his mother and asked, "Mom, would you sleep with Robert Redford for a million pounds?" to which his mother replied, "Definitely, I wouldn't pass an opportunity! like that." The boy then went to his sister and asked, "Would you sleep with Brad Pitt for a million pounds?" and she replied, "Of course I would - I'd be nuts not to." The boy then thought about it for a few days and then went back to his father who asked,"Did you find the difference between potentially and realistically?" to which the boy replied", yes, potentially we're sitting on two million pounds but realistically we're living with a couple of slappers". The father replied, "That's my boy!"
