Here's one for the Royal Family's blooper reel.

A little girl had the once-in-a-lifetime opportunity to meet Queen Elizabeth II today. She executed her part perfectly, offering a bouquet of flowers and making a nice little curtsy.

The queen begins to depart and the little girl, 6-year-old Maisie Gregory of Cardiff, lets her guard down—and immediately gets smacked in the face by a soldier pulling his hand up to salute.

"Ow!" she can be heard saying, which—by the way, in case you are ever smacked in front of the queen—isn't the polite exclamation. It's "What's the fuck, man?!"
