A boy goes up to his dad and asks the difference between "potentially" and "realistically." The father wants his son to learn, so, being the good dad he is, he gives his son an exercise.

"Go ask your mother, brother and sister the following question: Would you sleep with Brad Pitt for a million dollars?"

He asks his mother and she replies, "Well I don't know. That is a lot of money so I guess I would. We could use the money to fix up the house and send you guys to a good college."

His sister says, "Sure. He's hot. I'd do it for free."

And his brother answers, "Well I guess I would. That's a lot of money."

He returns to his father and his father asks, "Well, what did you learn?" The boy says, "Potentially we are sitting on three million dollars. Realistically we are living with two sluts and a fag."
