In addition to promoting his new film, Guardians of the Galaxy , Chris Pratt is also preparing to film the final season of Parks and Recreation, and apparently this makes it the perfect time to share some secrets from behind the scenes. While appearing on Late Night With Seth Meyers on Wednesday, Chris revealed that he once flashed costar Amy Poehler  while they were filming a scene in which he was supposed to be nude. Normally, actors and actresses wear skin-colored underwear while filming "nude" scenes, but Chris felt he wasn't getting the reaction he wanted from Amy while covering his modesty so, without warning, he decided to go "snake out." On the one hand, it got the perfect reaction from Amy, but it also earned him a stern warning from NBC for being inappropriate. Watch Chris tell the full tale above.
