Tourist finds himself looking down the barrel of a Queen’s Guard’s rifle

If you ever had reason to doubt that the Queen’s Guards are serious about their job, you may want to watch this video.

In an unintentional PSA, one tourist takes joking with the guard a bit too far and suddenly finds himself looking down the barrel of the guard’s gun.

The tourist in the video is seen mimicking, and quite possibly mocking, the soldier as he marches back and forth. But things take a turn for the worse when the tourist puts his hand on the guard’s shoulder where the guard’s rifle is resting.

The guard immediately shouts, "Get back from the Queen’s Guard!” and points his rifle at the tourist.

The video has gone viral with over 7.5 million views.

We hope this guy learned his lesson!
