The trailer for writers/directors Alex Gregory and Peter Huyck's comedy A Good Old Fashioned Orgy is now available online. Starring Jason Sudeikis, Will Forte, Lucy Punch, Leslie Bibb, Lindsay Sloane, Tyler Labine, and Lake Bell, the film tells the story of a 30 year-old man/child (Sudeikis) who decides to throw one last bash at the Hampton residence his parents are on the verge of selling. Judging from the trailer, the pic almost looks like an uninterrupted barrage of partying and general immaturity. In short, I'm looking forward to it. That said, I can't help but wonder how I can get my hands on one of those "Labor Day Orgy" t-shirts.

Hit the jump to check out the trailer. A Good Old Fashioned Orgy opens to select theaters this September 2nd.
