Chris Pratt is obsessed with being naked. No, really — the actor came clean about dropping trou during a recent appearance on The Graham Norton Show. Chris told Graham about getting in trouble for baring all when he was a kid, but he apparently didn't learn his lesson until adulthood. As it turns out, Chris took method acting one step too far while filming a scene with Amy Poehler for Parks and Recreation, the show that made us fall in love with him. Watch Chris explain what happened in the video, above, then see Chris wow Graham and Melissa McCarthy with his funny British accent.
