In 2005 I got a phone call to come to Shreveport and kill a dragon.Dragon slaying is a metaphor I adopted long ago – the origins of which are probably best saved for another story.Still, this was a mission.My friend Rachel ran the comedy club there at the time and thought I should come in for a particular weekend to “help her solve a problem”.She had called me more than a few times about it, actually, but that was all the information she would give me.
