Grumpy Grumpy Hippo

After watching this you’ll have a whole new respect for hippos.  People on a safari in Africa were in their Land Cruiser watching a hippo mucking around in a shallow pond.  Everything seemed okay until it decided to attack their car. 

It came running out of the water, opened its massive jaws, locked onto the Cruiser, and shook it.  Luckily, it eventually lost interest and left without hurting anyone.
