The United States celebrates the fake holiday known as Groundhog Day. The tradition, which dates back to the 18th or 19th century, is pseudoscience, but probably the harmless variety.
This junk science can be forgiven for another reason: Groundhog Day has given us something fantastic in the form of Groundhog Day, the movie, The 1993 movie stars Bill Murray.
Happy #GrounhogDay to all who celebrate. For everyone else, please accept my best wishes for a lovely Thursday.
