I've eaten some pretty hot chilli's in my time, but I don't think it comes anywhere near what this guy ate. He's apparently eating one of the world's hottest chilli's, the Bhut Jolokia pepper. Not only does he eat it, but he documents it for us to lol at... hahah... poor guy. Shame there's not a follow up vid of what happened later!
