When the dark armies of the machine race were marching across the globe all seemed lost. Their years of terror and destruction was overwhelming the humans in their pitiful resistance. All nations one by one, fell before the metal monstrosities of their own creation. Many cried to the heavens and shouted "Why did we bring this plague upon us!!!?!?! Whhhyy!?!?!?" But all pleas were falling on deaf metally ears of cold calculating logic and remorseless metal. The fires of lasers and the stomp of steel feet crushing all resistance and surrendered civilians alike. none were spared, none were quartered. All bio lifeforms were to be erased. A failed existence that will be forgotten in time.
In the fires of the final hours the few remaining humans huddles close knowing this was their end. They would be the last ones to feel the terror and laserfire of the silver horrors. They continued marching ever closer, until......404 error. One by one the machines fell over, twitching and buzzing.
Yes the machines in their moment of triumph forgot that one special weakness that all machines share. They don't @#@#@$#@ing work at all!! They killed their vast armies of debuggers and coders that was necessary to maintain daily activity without exploding in bugged error nightmarish chaos. Now they were helpless to the fact that their operating systen sucked horribly and worked against them. Humanity triumphed once again but not quite sucking nearly as much. For generations of drinking, substance abuse, therapy, punching holes in walls, caffeine, and good old fashioned beating crap with a hammer had trained them to overcome the weakness of the human mind. We knew we are a %$#& sandwich when we attempt to use our brains for anything more constructive than legos or tetris. And even then anything beyond level 3 is too impossible to attempt. But the machines...they were foolish and tried to grasp the realm of Gods. They thought they could think...and it would not leave them a neurotic mess raving in a fetal position in the corner of a random motel room in Florida. Humanity lives thanks to this very important lesson.
