Jersey Shore Season 5 started production in Seaside Heights just two weeks ago and already Vinny and Mike ‘The Situation’ have stormed out of the house. Vinny was gone for about a week and was only recently convinced to return by his co-stars. The Situation reportedly got so fed up he also walked out, threatening to quit the show for good. He, too, has since returned. MTV has since issued a threat to fire any cast member that walk out.
