Just heard on the nightly News that a group of Tongans went to a rugby match in a town in the USA to watch a fellow Tongan play in a game. The team with the Tongan player lost and his mates, to give him a bit of cheer, started to do the Tongan version of the Haka. The local police in attendance at the match had never seen this and fearing a riot was taking place, pepper sprayed the Tongans mid haka.
