You must kill the person below you, but here's the catch. You must do it creatively.
Ready....GO!

I will strap you to a chair that has a platform that I can raise and lower. Above you hangs a Ceilingfan with its blades made out of actual blades that are razor sharp. I will elevate you up..... And stop....inches away. I will leave you up there, strapped in with metal clamps, and let you starve and dehydrate. Then, Once you are almost dead, I will raise the seat a little more, and you will get beheaded. :) [spoiler] sorry m8 [/spoiler]
