The Queen's Guards' self-control is challenged every day by tourists who visit the royal residence and want to take photos with them. However, they are so well trained to remain firm as a rock that sometimes they look more like mannequins.

These guards are infantry and cavalry soldiers charged with guarding the official royal residence in London and they are known for their incredible ability to remain unmoved and expressionless when tourists approach them.

However, the guard featured in the video below couldn't keep a straight face when a funny tourist, identified by his friends as Yankel, performed a hilarious comic routine near him.

The soldier from the Household Cavalry Regiment tries to maintain an expressionless face as the tourist begins his hilarious speech saying that they went to school together in Kensington, but he finally breaks into a smile when Yankel claims that “his mum picked him up from school every day, until he was 20.”

When the guard finally giggles at his jokes, Yankel and his friends, who appear to be part of a group of Greek Orthodox tourists, cheer and jump through the courtyard victorious.

The video has already been viewed more than 80,000 times since it was uploaded to YouTube last week.
