Man bites dog.

As the old journalistic saw has it, dog bites man is not a story. For it to be a story it has to be the other way around, the unusual, man bites dog.

So I'm not all that sure that this from Reuters is in fact news.

A dog in Germany shot by a drunken man with a gun took swift revenge by biting off the end of the man's nose, authorities said on Monday.

I mean, OK, so it's vaguely amusing that the man was so imcompetent, and that the dog took his revenge. But is it actually news? Thatnthe dog bit someone who had just injured it?
