Trooping of the tongues
The Royal Family and sticking out their tongues appear to go hand in hand. Little Prince George and his nanny, along with a few other young Royals, were seeing the yearly Trooping of the Color procession via a window in 2015.
He was having so much fun celebrating his great-grandmother’s birthday that he put out his tongue in delight, and the cute moment was captured on camera. This picture is the most remembered one from the day, even though there was a lot going on throughout the parade.
