Happy Limerick Day

In honor of today being Limerick Day (in addition to it being the Laotian holiday of Rocket Day), I thought I'd celebrate it by posting someone else's work. And that is only because they put it better than I ever could.

There once was an old man of Esser,
Whose knowledge grew lesser and lesser,
It at last grew so small
He knew nothing at all,
And now he's a college professor.
-Noam Kuzar

Incidentally, the above limerick is found here. So take a little time and try one of your own. Not as tough as you'd think.
