I saw these official communications on a cute blog called http://www.howaboutorange.blogspot.com/, and I thought they were hilarious. Check out the online Bureau of Communication and send out your own fill-in-the-blank correspondence. Choose from a variety of forms, including Unsolicited Feedback, Airing of Grievance, Formal Apology, and Acknowledgement of Occasion.
