Uncyclopedia ('the content-free encyclopedia') is a website that parodies Wikipedia. It was founded in 2005. Originally an English-language wiki, the project currently spans over 50 languages. The English version has over 25,000 pages of content.
Various different styles of humour are used as a vehicle for parody, from sophisticated satire to the apparently random. Uncyclopedia has guidelines regarding what is and is not acceptable content and these guidelines have become progressively more strict as the site expands over time. The site has gained media attention due to its articles on places and people.
Uncyclopedia's stated goal is to be more successful than Wikipedia, and also to "provide the world's misinformation in the least redeeming and most searingly sarcastic and humorous way possible, through satire". Its articles contain information which is spoofed, fabricated or parodied to such an extent that very little factual accuracy remains, and information often contradicts itself. In a manner similar to Wikipedia's 'Five pillars', Uncyclopedia has a core set of rules called the 'Five pliers', including 'Satirical point of view'. Uncyclopedia has two main rules: 'Be funny and not just stupid,' and 'Don't be a dick'.
Even though uncyclopedia has been criticised for 'cyber bullying' and various other similar offenses, it remains an extremely popular source of entertainment especially when there's nothing better to do. Check it at http://uncyclopedia.wikia.com.
