I don't know the origins of this song. I believe it was writen by a NaNoWriMo participant, and is part of a larger work. I would credit him if I knew his name. It was introduced to me by way of some internet friends who are also NaNoers.
A struggling novelist tries his best to finish a scene in which a man comes home to find his wife guilty of something or other. While it may sound oddly disturbing to some, I think every writer can relate to the poor man at some point in his/her career.
And it's hilarious.
EDIT: Thanks to the efforts of our intrepid Rhoswen, I have been reminded that this is sung by The Playwright in the little-known musical "Enter The Guardsman". Full apologies to author, composer, and performer for my misrepresentation of their work.
She was kind enough to link me to this YouTube video of the same song performed by a contestant from American Idol. http://www.youtube.com/watch?v=um2rnjLBBuU Enjoy!
