David Aiken is a Canadian busker who goes by the moniker The Checkerboard Guy. He blends together comedy, juggling, and a bit of daredevilry into an act that's highly entertaining. He gets started with a trick involving a child from the audience, spinning a ball and putting it on their outstretched finger.
As the act goes along, he selects a guy from the audience to assist- in this case a big guy who looks like he just stepped out of the cast of Sons Of Anarchy, though with a smile. A little warm up includes yells, Viking style and karate style.
The Checkerboard Guy starts setting up for his finale, involving a very high unicycle and some juggling. A torch and an ax are two of the items that will be used. The third is one of the deadliest things known to humanity- a borrowed sneaker from a guy in the audience.
He gave his assistant a whiff of the sneaker.
Then it was time to start getting up on that unicycle. Another member of the audience was enlisted.
At this point he was warbling a few lyrics from Dan Hill's old song Sometimes When We Touch. The big guy was a great sport about it.
And soon enough, he was right up there, high over everyone else, balancing on that unicyle, starting to juggle. I could have sworn I'd caught a couple of the juggling moments on camera, but my camera disagrees with me.
