I <love> Excel btw. It was what I did for a living about..
   1998-2002 or so. Wrote these huge complicated things to process
   data with through Excel, make thousands of reports every week
   utilizing visual basic code.

   Loved it. Everything had to be PERFECT for it to work and I had
   to make it perfect - because I was the guy engineering the
   system to meet the specs... and dealing with the dirty data that
   was coming in and had to make it usable for Excel AND accurate..
   because it was a pharmaceutical company and... they.. .gotta be
   careful what they do and how they do it. Loved it. Lots of fun.
