A funny fail video has emerged from the UK of a moshing heavy metal fan accidentally cracking himself in the head with a big stick.<br /><br />In the clip, which was captured at the Six Fields Rock Festival on July 9, the man smashes the stick into a metal beer keg, which another concert-goer is holding in the air.<br /><br />Unfortunately for him, the stick bounces off the keg and cracks him in the forehead sending him falling to the ground.<br /><br />The man does get up off the ground to have another go but this time hits the keg with rather less force.
