"Hey man, just a reminder not to let any of your pussy-ass epileptic seizures ruin this concert." We'd love to see what kind of warning signs this roadie would write for an amusement park. "CAUTION: No knocked-up chicks, old dudes or fatties on this rollercoaster. Your stupidly misshapen bodies cannot handle its awesomeness."
