The Most Important Room

And on a lighter note....

In all libraries large or small
The most important room of all
Is not the paneled meeting hall,
But where one answers nature's call.

If you should doubt this, lock the door
Of every john on every floor
And see how long it takes before
You hear a loud collective roar.

For although books are really great,
There are some things that cannot wait
And one may only hesitate
So long before it grows too late.
