"Potentially and Reality"

Youngest Son:
Tell me Daddy, what is the difference between
"Potentially" 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, off 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! This is my fantasy!
Dad turns to his eldest son and asks him,
"Would you sleep with Tom Cruise for 1 million dollars?"

Eldest son: Yeah! Why not? Imagine what I could do with 1 million dollars!
I would not even 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 two hookers and a moffie!"
