Today is Groundhog Day in the US. I have never been a fan of Groundhog Day because I think it's no more sane to use a rodent for weather prognostication than it is for humans to try and predict the weather. Sure, animals have better instincts than humans (far better in most cases) but to suggest that on one day of the year a large rodent will be able to tell you when spring will arrive is just asinine.

I'm clearly not the only one who feels this way, as Adult Swim (the late night version of Cartoon Network) has put up a guide to understanding the Groundhog.
