Technology is awesome. The only downside is that you can't do anything without it being caught on camera.
"I remember back in my day," if you fell, people would laugh at you and that was it. Now, the entire world can laugh at your misfortune. Which is why I kind of feel bad for the chap in this video.
According to YouTube user SWNS TV:
The Queen's Guard was left red-faced as he slipped on a manhole cover during the famous Changing of the Guard. He lost his footing and slid sideways, knocked his bearskin on the side of the box and dropped his rifle. The soldier quickly scrambled to his feet as his colleagues marched past as if nothing had happened.
Click play, laugh, and try not to get caught if you happen to wipe out.
