An artist, a lawyer, and a computer scientist are discussing the merits of a mistress. The artist tells of the passion, the thrill which comes with the risk of being discovered. The lawyer warns of the difficulties. It can lead to guilt, divorce, bankruptcy. Not worth it. Too many problems. The computer scientist says, "It's the best thing that's ever happened to me. My wife thinks I'm with my mistress. My mistress thinks I'm home with my wife, and I can spend all night on the computer!"
