Cong-rat-ulations! It's the Year of the Rat. The lowly rodent can look forward to enjoying an entire year of celebrations and "infestivities."

As a matter of fact, I spied on a few of the rats the other day, at an international conference taking place in Boca Raton, Fla., in the field of rat research.

The goal of the conference was to discuss how to bring about "ratical" change to the new year while hopefully improving the image and reputation of the rat.
