As I prepared an old mental_floss magazine article for the internet, I was struck by YouTube's "related videos" section. It appears that the Maori war dance known as the haka has been adopted by not only rugby teams, but quite a few American high school football teams, too! You may enjoy watching these teenagers intimidate their foes and impress the girls with their moves.
