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 Patrice Motsepe 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!"
