Clinton is out jogging around in some of the seedier areas of Washington D.C. He notices a good looking prostitute. She sees this and calls out: “Fifty dollars!” He is tempted, but the price is a little high. So he calls back: “Five!” She is disappointed and turns away and Bill continues his jog.
A few days later, he finds himself jogging in the same area and as luck would have it, the prostitute is still there. But she want not come down on her price. “Fifty!” she shouts and Bill answers her: “Five!” No sale.
About a week later, Hillary has decided that she wants to get into shape so she demands to go jogging with Bill. They get to the seedy part of town and the same prostitute is still there. She eyes Bill and Hillary together and yells: “See what you get for five dollars!”
