A dancing tourist is going viral on Facebook after being recorded doing The Robot in front of a man dressed as a Royal Guard officer and apparently getting knocked out.
A bystander comes in to say "he's just doing his job, don't be an idiot," to which the dancing man replies "he can't do nothing."
Almost instantly, 'the soldier' delivers a solid blow to the man's face, knocking him to the ground and sending his bearskin cap flying.
Rather disappointingly, it's a fake. We estimate there's around a 0.0000000001% chance that the "soldier" in the video is a member of the Royal Guard.
He's actually joined up with YouTube pranksters Trollstation to scare tourists. Here's the full video:
The viral hit seems to be seems to be leeching off the success of recent videos involving the Queen's private guards, including one video of a man being practically trampled after he failed to move out of the way of a march, and another appearing to show a guardsman pulling his bayonet on a tourist who touched him.
