Difference between Potentiality and Reality
 Youngest Son: 'Tell me Daddy, what is the difference  between 'Potentiality' and 'reality'?' 
Dad: 'I will show you'  Dad turns to his wife and asks her: 'Would you sleep  with Robert Redford for 1 million dollars'?
Wife: 'Yes of course! I would never waste such an  opportunity'!  Then Dad asks his daughter, if she would sleep with  Brad Pitt for 1 Million dollars?
Daughter: 'Wow! Yes! He is my fantasy!' 
So Dad turns to his elder son and asks him: 'Would you  sleep with, Tom Cruise for 1 million dollars'?
Elder Son: 'Yeah! Why not? Imagine what I could do  with 1 million Dollars! I would never hesitate!'  So the father turns back to his younger son saying:  You see son, 'Potentially' we are sitting on 3 million  dollars, but in
'Reality' we are living with 2  prostitutes and 1 gay.
