Yes! It's officially the most fun day of the Dutch royal year -- the country's national day, when the Dutch people and their royals celebrate the late Queen Juliana's birthday in all sorts of wacky ways.
For instance, one of Princess Margriet's sons, Prince Pieter-Christiaan, decided to climb a rock wall while dressed for a business luncheon:
...and then Prince Friso's wife, Princess Mabel, walloped a group of children in a game of street hockey while wearing a jumpsuit from a Beyonce video:
... and then things got really crazy -- too much Heineken, methinks -- and Princess Margriet and her hubs decided to get a little amorous:
(Get a room, kids.)
... and the brewskis were definitely flowing in our favorite cake-hatter's corner, where it appeared that her team might not be winning whatever drinking game they were playing:
Drink up, Your Maj! You can't wimp out now that everyone's watching! I'm sure that dude on your left will hold your flowers...
(Seriously, I cannot stop laughing at this picture! Can we get more photo-ops with queens frowning at huge steins of beer? Please, world?)
On the bright side, the cake hat that Beatrix chose for the festivities was not only decorative (and I'm sure flavorful -- blueberry, probably?) but also helpful when it started to rain:
Much as I love the traditional royal clear plastic umbrella, this one is totally superfluous.
