Man Backflips Without Spilling His Beer

I'm not sure where in the world this is from, but it's a man in a bar holding a glass full of beer. There's a lot of chatter from other patrons in the bar then he does a backflip and sticks the landing all without spilling any of his beer using only one hand! It looks like he positions his hand underneath the glass at just the right moment. I have to admit that's a pretty amazing feat.
