When I first saw this on my local news I thought it was surely fake. So I did some investigating and sure enough, it really happened.
An Australian man found himself toe-to-toe with a kangaroo. The man went after the roo to save his dog, who was being held in a headlock by the marsupial.
Once the man freed his dog, he stepped in with the kangaroo and hit him with a right-hook.
The kangaroo looked a bit stunned and the man ran away. Shortly after the roo bounced away in bitter defeat.
