Jan,
          I hate to break this to you 
Oh, don't worry. I am not stupid, so I had already guessed that myself.
  but George Bush is an extremely common name
 in the US and Canada.  There are probably a few thousand of them. 
  Regardless of the provenance of his nick, he asked a
legitimate
 question.  If you have the answer give it to him.  If you don't then
 please keep the political rants to yourself.  There are other lists for
 that. 
I _did_ mark my reply [OT]. But indeed, last thing I want to do as start
a political discussion on this list. Please read me comment (rant is a
bit strong) as an [n]ethical one, rather than a political one.
