Watching McCain's histrionics the last couple of days brought back a memory that has been MIA since my law school days.  
I used to work in an outdoor parking lot in downtown San Diego to help pay for my way to school.  I saw one of the schizophrenic homeless guys that I'd come to know standing on a nearby street corner.  A few minutes later, he walked over and was suddenly standing above me.  He said, "You know, I was over on that street corner over there and all the oxygen was missing from the air and this match REFUSED to light!"  "But," he went on "I can control that!  WATCH!" 
He then struck a match, lit the cigarette butt that he'd found on the other corner and said, "SEE!  Don't ask me how I do it!"  
Funny how this story came back to me when I read about McCain now being able to debate since all is good in Washington again, since his arrival yesterday.
