One of Microsofts finest support techs was drafted and sent to boot
camp. 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 Microsoft
tech looked at his rifle and then at the target again. 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: Its leaving here just
fine. The trouble must be at your end!
