You set up this series of events. A grease slick on the floor, the boss doing his daily 8 a m walk through, the fork lift you have rigged to kick into drive. You have it all set up and you are standing beside the other tired workers plugging away at your job when he walks by. He slips in the oil spill and as he gets up the fork lift, unmanned comes at him full speed. A fork catches him in the temple and it splits his head open against a support beam. He is dead and they never know it wasn't an accident. A clever one you are. It's best not to piss you off.
