One of Microsoft's finest engineers was drafted and sent to boot camp. At the rifle range, he was given some instructions, 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 engineer looked at his rifle, and then at the target. He looked at the rifle again, and then at the target again. He then 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, where upon he yelled toward the target area: "It's leaving here just fine, the trouble must be at your end!"
