I have a little secret! I know why your wife can't get pregnant and it isn't because of the tiny little dick of yours :) She can't get pregnant because she used to be a man! What? She didn't tell you? Well, I know all kinds of secrets about you and that she-man. She (he) used to be my friend in college. Since you owe me money I'm going to blackmail you into giving it to me and if you don't pay then I'm going to tell EVERYONE that your wife had a sex change.
