Take a pressurized tornado cannon(they exist but I don't know their real name, they are used to demonstrate what different wind speeds are like and they shoot stuff into solid wood and stuff to simulate tornados) and stuff a ton of chopsticks in it and shoot the person below starting with the legs then the arms. Next step, while they are limbless take leeches and put them all over what's left of their limbs. While they are sucking his blood put a brown recluse on his stomach and keep aggravating it until it bite enough times. Final step, grab a chair and watch the horror you have created
