Sherlock Holmes' trusty sidekick, Dr. Watson, is a trustworthy chap, right? Only in the books. In motion, the guy's as creepy as a truckload of spiders.
This footage has been taken from the PC game Sherlock Holmes: Nemesis, which was released in 2007. It was uploaded in 2008. A while ago, yes, but we'd imagine it's only hit the limelight this week because the user has been in a psych ward for the past two years, undone by visions of a bearded man in a bowler hat lurking constantly in his peripheral vision.
While the music helps set the tone, I think it's the complete lack of movement on Watson's part that's the worst. No footsteps. No "Righto, I'll be off over here then, Mr. Holmes!". Just silence. Silence, and terror.
