of Dog, Bone and Fishes

When I was small, my primary school teacher told me this story:

Once upon a time, there was a dog with a bone in its mouth. It crossed a bridge and saw its own reflection in the river. It thought there was another dog in the river with another bone, so it stupidly jumped into the river, wanted to fight for another bone. Consequently, not only it didn't get the bone in the water, it lost its own bone as well.
Moral of the story : Don't be greedy.

Now, I am not primary school kid anymore. I have my own version of the story:

Once upon a time, there was a dog with the same bone, crossed the same bridge, saw the same reflection of itself, thought the same thing, did the same thing and jumped into the same river. Ok, of course it didn't get the bone in the river and it eventually lost his own bone, but instead of feeling sad and regret upon its loss, it started to blame the fishes in the water for stealing its bone away. The bone was somewhere in the water, just that the dog couldn't find it. The fishes actually didn't care about the existence of the bone in the water, because it doesn't cause any increase in BOD of the water, but they, being innocent, were blamed over something ridiculous which they had never done before. Now, there was no more peace in the water. Will the dog poison the river? We will see.....
Moral of the story: Don't know, think about it yourself.

You actually think that fish eat bones???
