One of Microsoft's finest 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: "It's leaving here just fine. The trouble
must be at your end!"
