Beware the wrath of Roman Atwood. Since creating his prank channel on YouTube in 2009, nearly all of his pranks have gone viral, regularly racking up millions of views. His most popular videos of the year had Roman turning his living room into a ball pit and pretending to get his son killed with an exploding ATV, much to the horror of his girlfriend Brittney. He now has a separate vlog channel, adding 30-minute slices of life near daily, featuring his family getting into wacky situations wherever they go. In 2015, he got his first movie deal, directing a prank film Natural Born Pranksters, and is working with Howie Mandel on a prank TV show.
