You May Celebrate, Or You May Third

The first of May, well that’s called May Day –
They danced ’round maypoles in its heyday.
The fourth of May too’s not a juke:
May the Fourth be with you, Luke.
The fifth of May, a storied bio:
Cinco de el mes de Mayo.
But sad to say, the last I heard,
The third of May’s just May the third.
