The footage here is a bit grainy, but not so grainy as to convince me that this video isn't what it purports itself to be. And that is... a beer chugging contest in Beijing between Yao Ming and Canadian mountain biker Geoff Kabush.

Well... OK... it doesn't hurt that Kabush recounts the story in this diary entry on Cyclingnews.com.

I'm not going to lie to you, Yao's better at this than I figured. I've analyzed the footage like it was the friggin' Zapruder Film, and I'm still not sure who won. Yao gets his cup down first, and Kabush doesn't even try to set his on the ground, but it almost looks as though they both finished at the same time. Neither of them crushes the cup against his head when they're done, so I'm really not sure if this can even be classified an officially sanctioned contest (also: poor form). Someone raises a red and white flag just before the images descend into chaos, but there's hardly enough evidence to declare a winner based on this tape alone. Rematch? See for yourself.
