Most people who have participated in sports have used or experienced some form of pre-game ritual. For me, it was eating orange slices before Little League.
For these two professional rugby teams, however, pre-game rituals work a bit differently.
This clip shows the two teams, New Zealand's All Blacks and Manu Samoa, performing their traditional pre-match war dances, known as the Manu Siva Tau (Samoa) and the Haka (New Zealand). After the historic match -- New Zealand's first on the Pacific Island nation -- the teams got together for a happy picture.
