I have a PHD and work with Dr. Hawking. :)
Actually, as you might surmise, given my extensive knowledge of RINO-rudy, I'm a proctologist (I know allot about @ssholes). :)
In truth, it's a nickname I got in high school, and it has stuck with me through the Marine Corps, and to this day.
My son was in the army for 4 years. He was a medic. He then joined the Navy, working in communications. He says everyone has always called him Doc.
You certainly have a way with words...
