Just when you thought that bears were the scariest thing you could encounter in the wild, it appears there is even something a bear fears and that's a moose. 

If you've ever been lucky enough to get close to a full-grown moose (without pissing it off) then you know just how massive and powerful they are. This viral chase comes to us from Montana where the bear had been stalking the moose and her cubs, leading the mother moose to chase the bear away. 

We usually say nature is brutal and while that remains true, nature is also pretty funny.
