London tourists, beware: The Queen's Guard don't like it when you touch them.
The guy in the video above definitely learns this lesson the hard way. After walking up and down alongside a member of the Queen's Guard, he eventually tries to put a hand on the Guard's shoulder. The soldier swiftly turns around, raises his rifle and screams "GET BACK FROM THE QUEEN'S GUARD," causing his assailant to jump halfway out of his skin.
The Guards' reputation is getting more and more badass by the day – it was only the other week that a parade of them trampled down a dozy tourist who was standing in their way.
