If You're a Pundit, This Is Your Day
Punned It Day is the kind of day on which, after you've said or written a pun, you say (aloud), "Oh yeah! Punned it!"
Just yesterday (so off by just one day for celebrating this day) I was exposed to several awful (i.e. good) puns. Here's my favorite.
"You call this a musical?" asked Les miserably.
That's partly because I can't stand that musical. Musicals are supposed to be fun. What's fun about being miserable?
So march forth and pun today. May the fourth be with you. Say something punny and make people groan.
If you can literally make someone groan aloud, you can be certain you've celebrated this day properly.
Of course, you can throw puns around any other day too. That's always a good thing.
