This vid is of the local high school football team and their pre-game ritual. It is a Polynesian war dance called the Haka. There is a large population of Tongans in Euless, Texas who were brought here by the airlines to do baggage handling and food service jobs at D/FW airport. Tongans are similar to Samoans, very large people. We see a lot of them at the hospital, almost every adult has diabetes and hypertension.
Anyhow, they make a hell of an offensive line! Trinity High School is #1 in the country I think right now.
