His father looks up thoughtfully and says, “I’ll demonstrate. Go ask your mother if she would sleep with Robert Redford for a million dollars. Then go ask your sister if she would sleep with Brad Pitt for a million dollars. Come back and tell me what you’ve learned.”

The kid is puzzled, but asks his mother. “Mom, if someone gave you a million 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 million dollars, would you sleep with Brad Pitt?”

She replies, “Omigod! Definitely!”

The kid goes back to his father. “Dad, I think I’ve figured it out. Potentially, we are sitting on $2 million bucks, but in reality, we’re living with two sluts.”
