A cop stops a biker on a Harley...
...for traveling faster than the posted speed limit. So he asks the biker his name.
"Fred," replies the biker.
"Fred what?" asks the officer.
"Just Fred," the man responds.
The officer is in a good mood and thinks he might just give the biker a break and give him a warning instead of a ticket. The officer then presses the biker for his last name.
The biker tells him, "I used to have a last name but I lost it."
The officer thinks that he might have 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 for pre-med. I went through medical school, an internship, a 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 and become a dentist. I got all the way through dental school and earned 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.
