The young boy says to his father, "Dad, what's the difference between po-tential and re-ality?"

"Well, go ask your mother if she'd slept with the milkman for a million dollars."

The boy trots off and asks mummy, then returns to Dad. "She said yes."

Dad then says, "Now go ask your sister if she'd sleep with the milkman for a million dollars."

The boys does so and comes back. "She said she'd sleep with the milkman too. But what's the difference between potential and reality? I don't get it."

"Well, son, we've the potential of sitting on two million dollars but the reality is we're living with a couple of whores."
