Once upon a time, the very idea of hurling anything at a member of the royal family would have landed you in the Tower of London on the charge of high treason.
But things could not be more different in 2017. The royal family are like, totally cool now. So cool, in fact, that you can squirt them with water and they'll love it.
That's what happened at the London Marathon as William, Kate and Harry cheered on runners from a water station.

One cheeky marathon runner -- whose identity is not known -- squirted the future king with water.
Just look at the sheer delight of Will's face...

Kate looked highly amused as water rained down on Will's face and clothes.

Anyone got a towel?
