It is not as bad as it sounds.  I've had two done twice so far.  Next one is about 5 years.  Preparation isn't great but I've gone through worse.  One they put their stuff in the IV, I remember nothing until I wake up and it's all over.  No pain at all.  People make too big a deal of it I think.  Funny story though.   
By the way, Dave Barry wrote a good one on the procedure.  Very similar to that one and it actually may be the same one, just don't remember it all.
