The difference between 'potentially' & 'realistically

[LONDONER]

A young boy went up to his father and asked him, 'Dad, what is the
difference between 'potentially' and 'realistically'?'

The father thought for a moment, then answered, 'Go ask your mother if
she would sleep with Brad Pitt for a million dollars.

Then ask your sister if she would sleep with Brad Pitt for a million
dollars, and then ask your brother if he 'd sleep with Brad Pitt for a
million dollars. Come back and tell me what you learn from that.'

So the boy went to his mother and asked, 'Would you sleep with Brad Pitt
for a million dollars?'

The mother replied, 'Of course I would! We could really use that money
to fix up the house and send you kids to a great University!'

The boy then went to his sister and asked, 'Would you sleep with Brad
Pitt for a million dollars?'
The girl replied, 'Oh my Gawd! I LOVE Brad Pitt I would sleep with him
in a heartbeat, are you nuts?'

The boy then went to his brother and asked, 'Would you sleep with Brad
Pitt for a million dollars?'

'Of course,' the brother replied. 'Do you know what a million bucks
would buy?'

The boy pondered the answers for a few days and then went back to his dad.

His father asked him, 'Did you find out the difference between
'potentially' and 'realistically'?'

The boy replied, 'Yes, 'Potentially', you and I are sitting on three
million dollars .

But 'realistically', we're living with two hookers and a queer.
