Season 2 - E6 - There are nude posters on the wall of an flat they visit. The flat (set) remains for approximately half the episode. They are mostly obscure but you can figure out they the posters contain topless nudity, especially in some cut scenes where they are slightly more visible because of the angle. Its never put into focus up close.
