Henry David Thoreau (born July 12, 1817), and the back-to-basics, back-to-nature philosophy of Thoreau is at the core of Friday's observance, Simplicity Day.
Friday will also be Different Colored Eyes Day -- an observance not necessarily limited to persons with two different eye colors in their very own eyes. The idea (or eye-dea?) is that Friday is a day to celebrate the fact that some people have brown eyes, others blue, others green... does that sound a little like a stretch to you? Blink and you'll miss it entirely.
Bill Cosby turns 76 on Friday (born July 12, 1937). Milton Berle was born on July 12, 1908.
