The merits of a mistress
An artist, a lawyer, and a computer scientist are discussing the merits of a mistress.
An artist tells of the passion, the thrill which comes with the risk of being discovered.
A lawyer warns of the difficulties. It can lead to guilt, divorce, bankruptcy.
Not worth it. Too many problems.
A 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!"
