I don't get it. First I filed this under 'Warrior Island' - just another stupid idea that would either never come off or fall flat on its stupid face.
Then, after seeing some of of the vids, I was convinced it was a troll job. But it seems they've put far too much time and effort into it for it to be a troll job...and maybe it's just me, but it doesn't seem *that* funny.
Part of me thinks it could be a semi-troll job, in that the guys making it are in on the 'joke' and the 'fighters' aren't. That would be slightly funnier if they were using "I'm an undefeated world UFC cage fighting champion" type dudes, but they're not. Kind of a dick move towards people who don't know any better, if that's the case.
Either way, real or fake, troll job or not, it's a massive pile of shit.
