Blonde and Psychiatrist
A blonde is speaking to a psychiatrist.
Blonde, "I'm on the road a lot, and my clients are
complaining 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 did the 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 figured it's because when I'm driving around, my
zip code keeps
changing."
