A few years back, a local radio station had what they called "Ginger the weather dog". The concept was pretty simple - in the morning the owner would offer the dog the opportunity to spend the day indoors or outdoors. If the dog elected to spend the day indoors, they took that to mean rain, otherwise they took it to mean that it would not rain.
Yeah, it was silly. But surprisingly accurate. Better than some of the other human forecasters that were on TV.
