Watching this scene, you could be forgiven for thinking that it's two men in kangaroo costumes.
But it's not.
It's two actual kangaroos having a fight in an Australian suburb - on the Central Coast, New South Wales, to be precise - which surely means that this can be described as 'a kangaroo street brawl'.
Of course, setting it Wagner's 'The Ride Of The Valkyries' just adds to the drama. Although personally, we would have gone for the 'Rocky' theme...
