Well, I'm not going to say it's a coincidence or anything, but today also happens to be the birthday of:
Isabella I, queen of Castile (1451)
Immanuel Kant, philosopher (1724)
Charles Mingus, jazz musician (1922)
Jack Nicholson film actor, writer, director, and producer (1937)
But if you look at the Commies who started Earth Day (I was in college when they had the first one) and the Socialists who now promote it, I believe it is a Commie celebration and has nothing to do with Jack Nicholson! eheheh
