This is just a very small clip of what happened in Argyle, Australia when a grandfather and kangaroo went head to head.
Apparently before this went down, the Kangaroo started to attack his dogs in his backyard. That's when Cliff Dess stepped in to protect them. It went on for a total of 6 minutes which during that time Cliff had his head gouged and his finger bit. The kangaroo was able to get away shortly after this clip.
