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
  Dingaling.  I  know -- a funny last name.  The kids used to  tease me all
  the time, so I stayed to  myself, 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 Dingaling, 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  Dingaling, MD, DDS.  Got bored
   doing dentistry, so I started fooling around with  my assistant and she
  gave me VD, so now  I was Fred Dingaling, MD, DDS, with VD.   Well, the  ADA
  found out  about the VD, so they took away my DDS.  Then  I was Fred Dingaling,
  MD, with VD.   Then the AMA found out about the ADA taking  away my  MD  because
  of the  VD, so they took away my MD leaving me as Fred  Dingaling with VD.
  Then the VD took away  my Dingaling, so now I am Just  Fred.'


  The officer walked away  in tears,  laughing.
