The Edinburgh Military Tattoo was on TV this afternoon. After hearing the introduction for the New Zealanders I had to go in a watch. So brilliant. Apparently they did this routine in 2006 - I found it on YouTube. The first couple of minutes are fairly routine but after that - so classic.

If you're wondering what the chant thing is that they do, it's called The Haaka. It's a traditional war chant thing that the Maori's use to intimidate their opponents by showing the fierceness/strength of their arms, legs, eyes and tongue. (I think the tongue part of it has to do with the cannibal history of the Maori, but I could be way off mark with that.)
I've only ever seen them do the Haaka on the football field before.
