Naked Man Caught Climbing Out Of Buckingham Palace Window [REAL OR NOT VIDEO]

In this video, that looks like it was shot by a tourist filming just regular activity around Buckingham Palace, caught in the background is a naked man climbing out of a very high window on what appears to be a makeshift rope.  Did Prince Charles come home early?

No explanation has been given about the authenticity of this video.  There's not much known about the video actually.

In the video, the naked man lets go of the makeshift rope while still fairly high up, experts say no one could live from a fall that high.  Real or Not...You decide.
