Most pacific nations have their own war dance. Samoa have the Siva Tau, Fiji have the Cibi. Tonga is called the Kailao or Sipi Tau. Australian Aboriginals have their own war dance as well.. Also Papua New Guinea, not sure what theirs are called.
Troy is one of my all time favorites. Not just because of his play on the field, but because he is a genuinely humble man off of it. Nothing fake/phony about Troy at all.
