Redditor pembull took a panoramic photograph of Fort Funston Beach in San Francisco. The picture here is cropped; see the full version here. A nice picture, but what's that in the middle? It's his dog, which was running when the picture was taken. Let's zoom in.
The poor dog became known as "Buttdog" thanks to this photograph, and now has its own subreddit. However, there is plenty more photoshoppery available in the original thread. Link
