A cop stops a Harley for traveling faster than the posted speed limit,
 so he asks the biker his name.
 
 'Fred,' he replies.
 
 'Fred what?' the officer asks.
 
 'Just Fred,' the man responds.
 
 The officer is in a good mood and thinks he might just give the biker a
 break and, write him out a warning instead of a ticket. The officer then
 presses him for the last name.
 
 The man tells him that he used to have a last name but lost it. The
 officer thinks that he has a nut case on his hands but plays along with
 it. 'Tell me, Fred, how did you lose your last name?'
 
 The biker replies, 'It's a long story, so stay with me.' I was born
 Fred Johnson. 
 I studied hard and got good grades. 
 
 When I got older, I realized that I wanted to be a doctor. I went
 through college, medical school, internship, residency, and finally got
 my degree, so I was Fred Johnson, MD. After a while I got bored being a
 doctor, so I decided to go back to school.
 
 Dentistry was my dream! Got all the way through School, got my degree,
 so then I was Fred Johnson, MD, DDS. 
 
 Got bored doing dentistry, so I started fooling around with my assistant
 and she gave me VD, so now I was Fred Johnson, MD, DDS, with VD. 
 
 Well, the ADA found out about the VD, so they took away my DDS. 
 
 Then I was Fred Johnson, MD, with VD. Then the AMA found out about the
 ADA taking away my DDS because of the VD, so they took away my MD
 leaving me as Fred Johnson with VD.
 
 Then the VD took away my Johnson, so now I am Just Fred.'
 
 The officer walked away in tears............................................................laughing.
