..between Possible and Realistic.

 A son asked his Father what the difference was between Realistic and Possible.

The Father replied, “Go ask your mother whether she would sleep with Robert Redford for one million pounds, and then go ask your Sister whether she would bed Brad Pitt for one million pounds.”

 So the son went off and found his Mother.

“Mother, would you sleep with Robert Redford for one million pounds?”

“Of course I would”, she replied. “I would be a fool to pass that up!”

Hmm, thought the Boy and off he went to find his Sister.

“Sister, would you sleep with Brad Pitt for one million pounds?”

“Hell yea!”, she cried. “I would SO do that man!”

Hmm, thought the boy.

A day later, and after much thought, the boy went back to his Father.

“Well son. Did you work out the difference?”

“Yes Dad” the boy replied.

“It is a possibility that we stand to make two million pounds! Realistically though…we live with two slappers!”
