Potentially vs Reality

A kid comes home from school with a writing assignment. He asks his father forhelp. "Dad, can you tell me the difference between potential and reality?"His father looks up, thoughtfully, and then says, "I'll demonstrate. Go askyour mother if she would sleep with Robert Redford for a million dollars. Thengo ask your sister if she would sleep with Brad Pitt for a million dollars. Thencome back and tell me what you've learned."

The kid is puzzled, but decides to ask his mother. "Mom, if someone gave you amillion dollars, would you sleep with Robert Redford?"

"Don't tell your father, but yes, I would."

He then goes to his sister's room. "Sis, if someone gave you a milliondollars, would you sleep with Brad Pitt?"

She replies, "O my god! Definitely!"

The kid goes back to his father. "Dad, I think I've figured it out.Potentially, we are sitting on two million bucks, but in reality, we are livingwith two sluts."
