In my Dark Ages when I was a 20-something yuffie with no reason to live, I rode the bus in Los Angeles. For ten years. It did not improve my disposition. I frequently had to take the Wilshire or Santa Monica buses across town, which is agonizing. They move at a crawl through heavy traffic, and going 10 miles takes two hours or more. At rush hour they're packed with the poor, the drunk, the young, the old, the multiply convicted felons, and all of the 100% disabled insane people. All of us got to share each other's vivid personalities, differing cultural sensitivities, and rich evocative aromas.
Dr. Geek was a regular on my trips from the Westside to Downtown. He was a very large man with an expansive manner, and he'd spent the day in the heat singing so his body's natural glow was evident to all the senses. He often wore one of those huge foam cowboy hats you see at county fairs, and carried the tool of his trade: a gigantic boom box that seemed to have sharpened corners and weighed about 400 pounds, or half the good Doctor's mass.
He would lurch onto the bus, boombox blaring, and announce to the world that "DR. GEEK IS IN!" Pushing backwards, not with malice but with an infectious joie de vivre, he'd get to about the middle of the bus and yell out again "IT'S DR. GEEK!"
For the next two or more hours, the Doctor was in session. We all got some free raps (he'd offer to customize without the usual fee), and if no one was up for it, he'd lay some rhymes out for us, freestyle. Sometimes he'd use the boombox and other times it was just an a cappella hip hop cornucopia.
The first time, it was a blast. The second time, it was a smaller blast. The third time, it sucked, especially since he kept backing into me with his wall-like back while he was caught up in the passion of yelling "I'M THE ORIGINAL/DR. GEEK/AIN'T NO ONE ELSE ON/VENICE BEACH" or something similar.
It was nice to see that he has a website and isn't dead. At the time I wanted him to go away and die, but now I'm happy that the Doctor is still living large.
