I was looking at some fake news bits from "The Onion" on youtube and one of them was an impassioned sports report about something called Sepak Takraw. The report was fake but it turns out Sepak Tekraw is not. I'd never heard of it, but it's a sort of cross between soccer and volleyball played in Thailand and Malaysia and other Asian countries. It's on an indoor volleyball type court but with a lower net, and players can only hit the ball with their heads or kick it ...no hands can be used. The play is fast and very acrobatic. I don't see how these guys don't get hurt. Anyway, here's a clip...pretty cool stuff.
