How do you sprain your ankle on purpose?

I have had a sprained ankle and it hurts like hell, but if you really want to here are three things you can do:

1.) You can put on some high heels and step off of an office chair and tilt one ankle to the side

2.) You can sit on a chair or couch and tilt your foot to the side and stand up

3.) You can get some high heels on and get 5-10 small balls (tennis or racket)

and jump around until you cant jump anymore
