Every year since 1199 the people of Atherstone, England have played something called medieval football. You have to watch the video to really get a feel for it but basically it looks like a great excuse to get into fights without being arrested. The idea is to end up with the ball in your possession at the end of the two hour game which basically has no rules except for where it's played and "no killing anyone". Ribbons are attached to the ball which players try to retrieve and there's a golden penny which is prized also.
Check this out and see if you'd to have a game played maybe on Erie St downtown.
