Prince William Scolded by 'The Boss,' Queen Elizabeth II

The incident happened during last weekend's Trooping the Colour.

— -- There's a reason why Queen Elizabeth II is affectionately known as "the boss."

William, who calls the monarch "Granny," and George who refers to her as "Gan Gan," knew Her Majesty meant business.

The priceless reaction of 2-year-old Prince George, who put his hand on his face, was the icing on the cake.

Trooping the Colour is the annual tradition to celebrate Queen Elizabeth II's official birthday.
