A blonde is speaking to her psychiatrist. “I’m on the road a lot, and my clients arecomplaining that they can never reach me.” Psychiatrist: “Don’t you have a phone in your car?” Blonde: “That was a little too expensive, so I didthe next best thing. I put a mailbox in my car.” Psychiatrist: “Uh … How’s that working?” Blonde: “Actually, I haven’t gotten any letters yet.” Psychiatrist: “And why do you think that is?” Blonde: “I figure it’s because when I’m drivingaround, my zip code keeps changing.”
