Joe is speaking to Dr. Mark, a psychiatrist.
Joe, "I'm on the road a lot, and my clients are
complaining that they can never reach me."
Dr. Mark, "Don't you have a cellphone in your car?"
Joe, "That was a little too expensive, so I did the next
best thing. I put a mailbox in my car."
Dr. Mark, "Right.....how's that working?"
Joe, "Actually, I haven't gotten any letters yet."
Dr. Mark, "And why do you think that is?"
Joe, "I figured it's because when I'm driving around, my
postal code keeps changing."
