Ode to the Typographical Error

The typographical error is a slippery thing and sly
You can hunt 'til you are dizzy, but it somehow will get by.
'Til the forms are off the presses, it is strange how still it keeps.
It shrinks down in a corner and it never stirs or peeps.
That typographical error, too small for human eyes.
'Til the ink is on the paper, when it grows to mountain size.
The boss, she stares with horror, then she pulls her hair and groans.
The copy-reader drops his head upon his hands and moans.
The remainder of the document may be clean as clean can be,
But the typographical error is the only thing that's seen.

=====================
This is not original and exists in many forms on the Web; it is what I've been dealing with for the last week or so as I and others have worked to purge typos from very important documents. We are very nearly done.
