I was once at a Lamb of God show in Dallas where during the song Black Label the crowd did the wall of death. For you nonmetal heads, that means we split the crowd in two and when the song began we ran at each other full force. Anywho, there was this kid (about 15 or so) across the way from me. I could tell he had never been in a wall of death as he was freaking out. He tries to run away when we start running at each other then suddenly this big Viking looking dude with a beard grabs the kid and throws him over his shoulder and just charges headlong. Funniest thing I've ever seen at a metal show!
