You should try the "rim stomp" game.
1.) Take a rim that hasn't been laced up
2.) Stand it on edge.
3.) Jump up
4.) on to
5.) The rim
6.) With both feet, and try to taco it. I reccomend doing it on concrete.
I tend to loose as I'm only 140lbs, so most double wall rims land me on my a**.
Oh and your automaticaly disqualified if the rim could be used by someone else.
