Well I guess the hand, or the tissue covering the bionic part, it would be, I guess...you know, could've come from a serial killer. And then one day soon, maybe you're shaving, and you find out it has a mind of its own. It's a force of pure evil, and it starts dragging you out into the city at night. Just cats at first. But once the hand gets a taste for killing, it's only a matter of time before you're out there strangling male prostitutes, and then posing them in grotesque and horrific parodies of Mentos ads. You know, The FRESHMAKER!
