Groundhog Day

When I picked D up from pre-k, he was wearing this hat.  I had completely forgot about groundhog day.  One of his teachers told me she asked the class if anyone knew which holiday it was that was in February and involved a little critter that lives underground and D raised his hand and said it was Groundhog Day.  Then she asked what happens if the groundhog sees his shadow and D replied, "There will be 6 more...months...of Christmas."
