Clara recently found this very cool post (with hilarious title) on Tumblr and knew I would love it (she was right, obviously). While the concept is pretty good and the photos are quite cool it’s actually the title of the post that caught my eye. No, not just because it has the word “porn” in it. In fact, you might be surprised to find out that stairs and pornography actually have something in common–you just have to consider the origin of stairs. Please note that there isn’t any pornographic content in this blog so if you came here looking for that, we’re sorry to disappoint.
