Companion pet fights!

So I had this idea today, and I don't know if its been said already, but wouldn't it be awesome if bliz would create animations to make pets fight? Not like serious fights or anything, but say I'm walking around with my Lashtail Hatchling, and some other person walks by with an Obsidian Hatchling, and mine runs over and they start fighting.

Like cartoons, where its just a big ball of dust and smoke, and you see heads stick out, or a random leg pop out, one tries to crawl out but the other one pulls it back in, and in the end the smoke clears and the winner is standing victorious and the loser crawls away. It would be random every fight who would win or loose, and it would all be for fun, just to watch. Go go bliz make it happen!
