We've always thought that members of the Queen's Guard weren't supposed to move or talk, but this guy breaks convention when he screams at a little kid who gets too close. Maybe all the extra security for the Olympics has him a little tense?

The child in question is one of several who makes the mistake of approaching a cordoned off area. So, the guard pivots on his heel, marches straight up to the kid and shouts, "Get off the fence!" With that, he spins and returns to his post without another word.

The children, meanwhile, look momentarily stunned, then start to giggle. It'd be an even funnier moment if this overly-tense guy wasn't also shouldering a gun.

What do you think? Did the guard overreact? Or is he making a good point about the child's proximity to the fence?
