You, Me and Dupree(2006)

Carl and Molly have found the one unfortunate hitch in their perfectly constructed newly wedded world: Dupree. A slacker with the soul of a poet, Dupree just can't seem to catch a break from "The Man." When he takes a week off to go be the best-man at Carl and Molly's wedding in Hawaii, Dupree gets the unceremonious heave-ho from his boss. Now jobless, car-less and evicted from the cot at his favorite watering hole, he just needs to crash with the Petersons for a couple of days; okay, maybe a month or so. At first, Carl is psyched to have the couch guest while Molly bears the brunt of Dupree's well-meaning antics. But, as Carl becomes buried in his grown-up job of land development and headaches, he finds it hard to juggle Dupree and his newlywed responsibilities. As time passes, his and Molly's houseguest uses his ample spare time to become a great companion to her, underscoring Carl's new workaholic tendencies. Even Molly's dad begins to fall for Dupree's carefree wisdom, frustrating Carl to no end. Soon, everyone--but Carl--begins to root for Dupree to stick around. But just as the impish buddy starts becoming a fixture in the Petersons' home, three becomes not just a crowd, but a full-blown comic catastrophe. As the couple realizes their ideas of a white-picket fence marriage are morphing, their loveable pal serves as a daily reminder that finding your inner Dupree might just be one of life's hidden secrets
