I think this guy who challenged robin gracie at a seminar in the year 2003 is retarded. The gracie challenge is long dead and it was only meant for a time when people only trained one style and no one knew the effectiveness of jiu jitsu back then. Now days, everyone knows how effective it is, it isn't even a question anymore. This wasn't gracie jiu jitsu vs some random traditional martial artist, this was gracie jiu jitsu vs an MMA fighter who knew jiu jitsu. Technically, gracie jiu jitsu still won this fight because they both used it. There are many fighters that could beat any gracie in MMA these days and this dude beat one after he did a long seminar and wasn't prepared. This guy is a punk for doing this. Of course the gracies handled this horribly, as they always do.
