What is a good way to give yourself a hanging wedgie?

What you do is you sneak up behind your victim, and you pull (you get the idea). Then you hang them to something like a pole or something that you can easily put the undies on so they cant get down. this will be easier if that person is light weighted. so try it to a friend or a nerd. But yo shoul try and do it to a girl and see what happens. but you dont have to.
