One of Microsoft's finest techs was drafted to be on the Bill Gates
Rifle team. At the rifle range, he was given some instruction, a rifle
and bullets.  He fired several shots at the target. The report came from
the target area that all attempts had completely missed the target. The
tech looked at his rifle, and then at the target. He looked at the rifle
again, and then at the target again. He put his finger over the end of
the rifle barrel and squeezed the trigger
with his other hand. The end of his finger was blown off, whereupon he
yelled toward the  target area,"It's leaving here just fine, the trouble
must be at your end!"
