"Suddenly there came a tapping ..."

Commenter Susan at Ann Althouse's Osama bin Laden poetry contest:

Once upon a midnight dreary, Osama pondered, weak and weary,
Over many a quaint and curious volume of forgotten lore,
While he plotted, clearly scheming, suddenly there came a tapping,
As of some SEAL gently rapping, rapping at his chamber door.
"'Tis some visitor," he muttered, "tapping at my chamber door -
Only this, and nothing more."

Read the whole thing - it is actually quite literate and ends with a bang.
