If you are wondering what a Goober is, there is a picture of one at:
A goober is speaking to her psychiatrist.
"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?"
"That was a little too expensive, so I did the next best thing. I put a mailbox in my car."
"Uh. How's that working?"
"Actually, I haven't gotten any letters yet."
"And why do you think that is?"
"I figure its because when I'm driving around, my zip code keeps changing."
