Uncyclopedia is a satirical online encyclopedia that parodies Wikipedia. Its logo, a hollow "puzzle potato", parodies Wikipedia's globe puzzle logo, and it styles itself "the content-free encyclopedia", parodying Wikipedia's slogan of "the free encyclopedia". Founded in 2005 as an English-language wiki, the project spans over 75 languages as well as several subprojects parodying other wikis. The English version has approximately 36,000 pages of content, second only to the Portuguese. Uncyclopedia's name is a portmanteau of the prefix "un-" and the word "encyclopedia".
