James Franco and Seth Rogen — these kooky guys just love to run around in their birthday suits. About two weeks after jumping out of a cake sans clothes on "The Tonight Show" Franco has taken to Instagram posting nude photos of the duo in the woods, hinting they might be involved in a "Naked and Afraid" episode for Discovery. 

In the photo above, Franco wrote “Boom boom, NAKED and Afraid. Me and Seth, in the bush, naked, together. For reals.” Then in the photo on the left, Franco captioned, “See if me and seth can make it, NAKED and AFRAID!!!! Wtf?! You’ll see……..”. In the photo on the bottom left, the duo use their manhoods as swords with the caption, “Just survivin’, Naked and Afraid. This is how we do it.”
