"I have a problem," Suzanne complained to her friend, "I'm on the road a lot, and my clients are complaining that they can never reach me."
"Don't you have a phone in your car?" asked the friend.
"That was too expensive, so I did the next best thing. I put a mailbox in my car."
"A mail box? Does that work?"
"Actually, I haven't gotten any letters yet."
"And why do you think that is?"
Suzanne thought for a moment, then replied, "I figure it's because when I'm driving around my zip code keeps changing."
