I know... it's like a week late but I needed to share the following link. Not that I tend to be a downer but I gave up on this one a couple of freezing years ago...
Groundhog Facts You Didn't Know
1. Punxsutawney Phil has seen his shadow 97 times, has not seen it 15 times, and nine years are unaccounted for.
2. The National Climatic Data Center reportedly stated that Phil's prediction's have been correct 39 percent of the time. This number is in conflict with Phil's club, which states he's been right 100 percent of the time.
3. According to the funny website groundhog.org, there's a legend that during Prohibition, Phil threatened to impose 60 weeks of winter on the community if he wasn't allowed a drink.
4. In the years following the release of Groundhog Day, a 1993 film starring Bill Murray, crowds numbering as high as 30,000 have visited Gobbler's Knob, a tiny hill in Punxsutawney where the ceremony takes place.
5. Though groundhogs typically live only six to eight years, Groundhog Day lore suggests that Phil drinks a magic elixir every summer, which gives him seven more years of life.
