Oh, Harry! Prince plays a purple prank on royal photographer in New Zealand

When you hang out with Prince Harry, anything can happen.

One minute, you think you're just playing a friendly game of poker, and the next, he has no clothes on.

While he didn't get naked during a charity appearance in New Zealand, he did make a mess of royal photographer Arthur Edwards' balding head. After getting purple paint brushed onto his hand to add to the handprints on a mural at the Turn Your Life Around youth center, Harry decided instead to slap his hand on the photog's dome.

Edwards, who we assume has seen Harry in all sorts of silly situations, took it in stride and even retweeted his moment in front of the camera.

Oh, Harry.
