Winnebago Man is a 2009 American documentary feature film directed by Ben Steinbauer that follows the Internet phenomenon created by a series of twenty-year-old outtakes from a Winnebago sales video featuring profane outbursts from the salesperson, Jack Rebney. Originally intended as an inside joke, the video spread across the globe first on VHS tape then via YouTube and other online video sites, earning the salesman the title of "The Angriest Man in the World".
