Elevator Ghost -- Freaky

It takes a while to get to it, but it's freaky when it appears. Apparently it's a hoax, but the video saying it's a hoax doesn't say much. Nice special effects at the very least! You'll notice the guy who's in front of the ghost, though. Just before he starts walking he reaches behind his back slightly and does something. His hand movement doesn't seem natural for someone preparing to walk straight ahead.
