I guy I used to work with composed a really vitriolic not-for-flight five-page email resignation letter that he composed to make him feel better. It named-names and blew the whistle on corners cut and bad practices. Once he had vented his spleen by sending it to a few colleagues, he suddenly became really paranoid that it might fall into enemy hands, and tried to access everyones mail account to confirm they had deleted it... that resulted in hours of fun for all the family.
