Naked man seen climbing out from a window at the palace of the Queen of England in London

A few days ago, a bizarre video was posted on Youtube showing a naked man climbing down from a window at Buckingham Palace. The incident was captured by a bystander who shared the video online but some people think it's a hoax as it didn't make sense to them that a completely naked man would be climbing the walls of the Queen of England's home. Plus the Palace declined to comment on the video.
