For  my fellow insomniacs, this news should make you throw up some horns. Nathan Explosion, Skwisgaar Skwigelf, Toki Wartooth, "Pickles the drummer", and William Murderface return to Cartoon Network's Adult Swim with Season 4 of 'Metalocalypse' on Sunday, April 29th at 12:15 a.m.

If you're a metal music fan who hasn't seen Metalocalypse, you are slacking. Head over to the Metalocalypse page on AdultSwim.com and get caught up on the last couple seasons.
