MTV has greenlit two series from former JACKASS stars. THE NATURE SHOW will see Chris Pontius and Steve-O traveling to exotic locales to frolic with wild animals. Bam Margera will head an untitled series similar to JACKASS. He will continue to play pranks on his parents and friends. "We didn't want to do JACKASS again," said Brian Graden, president of entertainment at MTV and VH1. "We thought there was enough distinction to their ideas that we would avoid repeating ourselves."
