I slipped on the cement floor in my apartment building's basement. My left elbow hurt. I figured it was dislocated, so I tried to wiggle it back into place. I had, in fact, fractured it, bigtime, requiring surgery and nine lovely screws. (Yes I do set off metal detectors.) Also, a little nerve damage, caused, I suspect by my trying to relocate my "dislocated" elbow.
The food at Shadyside hospital was lousy. But they were the only place in town that got the SciFi channel, so all my friends came to see it, and incidentally me.
