A boy goes up to his father and asks him, Dad what's the difference between Theory and Reality ? (good question, son). The father tells him to, "go and ask your mother if she would sleep with a man for a Million Dollars ? and then and ask your sister the same question !
Then come back to me." The son does just that, and when he returns to his father.
The father asks, "So ..... what did they say ? " The son answers, "They both said they would do it" Well, in Theory we're sitting on 2 Million Dollars. In Reality we're living with a couple of potential prostitutes.
