Head Banging Turtles

As far as pets go, I would not think that a turtle would make a super awesome pet.  Turtles don't play catch, they don't warn you about an intruder and a turtle is hard to get to know.  It takes them a while to come out of their shells.  That being said, these two turtles may have changed my mind.

Check out this video of two turtles head banging.  Not sure if they were trained or just reacted on their own.  Nonetheless, they make turtles way cooler than I thought they were.
