Uncyclopedia, like all wikis keeps an extensive history of every page between its creation and the last edit. Every single version is stored on the database and can be re-stored very easily. It is this very principal that allows reverting and rollback to take place. However if a page is vandalized over a long term (gradually vandalized by n00bs and anonymous users) it may appear totally irredeemable and either have a 30 day maintenance template slapped on it or be put on Votes for Deletion. Which takes me to this. Check the history DAMMIT!
