If you look thru the list of calendar dats and events, every day is....well something.   National this-day or that-day.     Some are legit, some are stupid, and some are just fun.       Earlier this month on the 4th, it was the only day of the year that's also a complete sentence....March fourth (march forth, get it?).   In a couple months, it'll be Star Wars Day on May 4th.    (may the 4th be with you....get it?)       Today is one of those days....it's March 14th....or numerically 3/14.      For the non-mathmeticians in the audience, 3.14 is how 'pi' starts...so today is officially Pi Day.     To celebrate, here are a bunch of Pi jokes for the nerds in our midst....
