It is the distant future and the humans are dead! While I was busy building websites, Themebot was busy scheming to take over the world. Unbeknownst to me, my entire central nervous system and brain were replaced with a motherboard and circuitry while sleeping. I still look human and smell like a human, but I am now a robohumanoid.
There are other humans who were chosen to be spared, who were not exterminated by the poisonous gases. If you are reading this, rest assured that you too are a robohumanoid. Themebot has saved the world and there is no more unhappiness. Time to party, robo style!
