The New Zealand national rugby team, called the All Blacks, performs a traditional Maori war dance (a haka) prior to international matches. They first did this in 1884 during the team’s first trip overseas, and they’ve been doing it ever since. It’s something of a rugby tradition.
Today I ran across an animated version with gingerbread men doing the haka. It was apparently an ad for the New Zealand bakery challenge. Quite funny. Assuming, of course, you’re familiar with the whole haka thing.
