casimir pulaski dayMarch 5, 2007
It’s today! It actually exists! Though Sufjan’s words did not describe what the day is officially about, it’s always on the first Monday in March (“On the first of March / On the holiday”). Casimir Pulaski was a Polish dude who was a Revolutionary War cavalry officer. Thanks, Wikipedia!
Umm to get a total boner and celebrate the day in style, watch THIS NUGGET.
