Just Fred
A cop stopped a Harley biker for traveling faster than the posted speed limit, so he asked the biker his name.
"Fred," he replied.
"Fred what?" the officer asked.
"Just Fred," the man responded.
The officer was in a good mood and figured he might just give the biker a break, and write him out a warning instead of a ticket. The officer then pressed him for the last name.
The biker said "I used to have a last name, but I lost it."
The officer thought that he had a nut case on his hands, but he played along with it. "Tell me, Fred, how did you lose your last name?"
Fred replied, "It's a long story, so try to keep up. 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 again and got my degree, so I was Fred Johnson, MD, DDS."
"Got bored doing dentistry, so I started fooling around with my assistant. She gave me VD, so 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.
