He's not a trained barber, but Mel Gibson has enough experience cutting hair to be confident enough to cut a stranger's hair.

"I used to cut my children's hair when they were little. They didn't have a choice in the matter," he recalled. "It wasn't a great job, but it got them through. They're still alive."

New Zealand native, William might have been left with less hair than he hoped after his encounter with Mel's razor, but considering the story he's going to have to tell his grandkids, we think he'll get over it pretty quickly. 

He also got to have a crack at trimming Gibson's beard and to be honest it's hard to know who should feel more aggrieved against who for the end result.
