A distraught young man made an appointment with a psychiatrist.

"I was out of town on business," he told the doctor," and I wired my wife that I would be coming home on Tuesday, instead of Wednesday. When I got in I went straight home as fast as I could, and when I got there I found her in bed screwing my best friend!"

The man then broke down into uncontrollable tears.

The doctor considered the problem for a couple of moments then said, "Maybe she never got your telegram."
