One of the most recognizable symbols of the British Monarchy is "The Queen's Guard" which is a group of soldiers that are tasked with guarding the Queen and her residences. 

These soldiers are hand picked from five elite regiments within the British military and are very serious about their commitment to duty. 

You will commonly see tourists heckling these soldiers in an attempt to make them laugh or otherwise respond, because of the common belief that they are not allowed to react in any way. 

So is this common belief really true? Are the soldiers forbidden from reacting to goofy tourists? This video by the Today I Found Out YouTube channel has the answer!
