A jousting tournament? Sounds kind of trammy-ish but it could be fun. Have a reasonable entry fee, winner takes all. 2 riders mounted, ride at each other with lances with dismount prepped (for those of you who don't know you can dismount someone with a lance while on mount, as long as they have a lance armed as well). do one pass at a time until someone gets dismounted. If you get dismounted you are eliminated, winner goes to the next bracket. Reply here with your insults!
