How to break/badly sprain an ankle?

I really badly want to do this. I want crutches and a cast. Please help! you may think im weird but please tell me how! please no rude comments and none like jumping off a cliff! Please. Im begging you. Also can you make it something i can do at recess or home (most likely at home) Can you ALSO try to make it with the least pain. thanx. u guys are awesome if u can do this for me. i have changed the best answer two 35 points. If u can do it you can do this it would mean the world to me.
