To celebrate, here's a picture of another famous groundhog...
Yes, it's Pardon-Me-Pete, the groundhog from the 1979 TV special Jack Frost. Nowadays Jack Frost is shown with the Christmas specials (because it's wintery, I guess) but I remember its first airing, and it was indeed shown on Groundhog Day (or a few days before)...
Here's another groundhog. I don't know if he's famous, but he hangs out with cheerleaders...
Actually, I don't think that's a groundhog at all. I think those nefarious Texans have slipped in a prairie dog...
If Texans don't quite get Groundhog Day, you can bet the French are really confused. Click here to see their take on it (NSFW)...
