Australia: still the country where everything wants to kill you. And each other.
You've probably seen kangaroos fighting in a wildlife documentary at some point in your life and laughed about how cartoon-ish their behaviour is, but this scrap happened right outside people's homes, with this video's uploader Rodney Langham getting out of his car and approaching the two 'roos to get a better shot of them beating the snot out of each other. And as you can see, it's anything but cartoon-ish.
Big thumbs up to Rodney for adding in the classical soundtrack though, it really does make the video.
