Tonga and Samoa performed their pre-match war dances simultaneously and barely inches apart in the Rugby League World Cup semi-final.
The competition has taken place in England this year, and kicked off last month. It has now reached the semi-final stage, and there were a collection of quarter-final games that took place last weekend.
The pick of the bunch was Tonga v Samoa at Halliwell Jones Stadium in Warrington on Sunday. Apart from being a classic match itself, it's what happened before the game that has captured the attention of social media.
Rugby fans are familiar with seeing the 'Ka Mate' haka performed by New Zealand, like we saw against Wales on Saturday.
Tonga's pre-match ritual is entitled 'Sipi Tau', whilst Samoa's is 'Siva Tau'. Viewers were treated to a fiery rendition of each prior to the big quarter-final match, before opposing players embraced and shook hands. The video has been watched more than 250,000 times, with viewers marvelling at the spectacle.
According to Living Heritage , here is the English translation of Samoa's Siva Tau.
The Manu Samoa, may you succeed in your mission,
The Manu Samoa, here I come,
There is no other Manu (team) anywhere,
Here I come completely prepared,
My strength is at its peak,
Make way and move aside,
Because this Manu is unique,
The Manu Samoa,
The Manu Samoa,
The Manu Samoa reigns from Samoa.
Siale Piutau, former Tonga rugby union captain, explained the meaning of Sipi Tau in 2015.
"It just means we want to be strong up front, our backs are going to run. It's just pretty much laying everything down - we're going to lay down our lives out on that field." said Piutau, older brother of All Black Charles Piutau.
Clips of the face-off have been posted to social media by BBC Sport, picking up over 550,000 views on Facebook and Twitter in two days.
Samoa would go on to win the match 20-18, setting up a semi-final with hosts England at Emirates Stadium in London on Saturday. The other semi-final will be played between Australia and New Zealand on the Friday.
