The father replies: "Well son, I could give you the book definitions, but I feel it could be best to show you by example. Go upstairs and ask your mother if she'd have sex with the mailman for $500,000."

The boy goes and asks his mother: "Mom, would you have sex with the mailman for $500,000?" The mother replies: "Hell yes I would!"

The little boy returns to his father: "Dad, she said 'Hell yes I would!'"

The father then says: "Okay, now go and ask your older sister if she'd have sex with her principal for $500,000."

The boy asks his sister: "Would you have sex with your principal for $500,000?" The sister replies: "Hell yes I would!"

He returns to his father: "Dad, she said 'Hell yes I would!'"

The father answers: "Okay son, here's the deal: Hypothetically, we're millionaires, but in reality, we're just living with a couple of whores."
