Articles
Uncyclopedia encourages satire that is close to or resembles the truth. However, many articles employ absurdist humor and little, if any, factual accuracy remains. For example, Uncyclopedia's article about Wikipedia claims that Wikipedia is a parody of Uncyclopedia, not the reverse.[15] Many articles on the site contradict each other, even articles on the same subject.
Like Wikipedia's "Five pillars", Uncyclopedia has "Five pliers", including "Satirical point of view".[16] Its code of conduct follows from three main rules: "Be funny and not just stupid", "Don't be a dick", and "Dance like you've never danced before!"[3][17]
Parodying Wikipedia's article review service peer review, Uncyclopedia has a "Pee Review" where authors seek review by other Uncyclopedians on humor, grammar, spelling, use of images, and overall presentation.[18][19] Users can post to other wiki pages to solicit coding help and review or request user-edited images. Like Wikipedia, Uncyclopedia features articles and images on its front page. A system of user voting decides which articles and images to feature, usually deciding based on humor and writing quality. The site also welcomes audio contributions such as narration of articles. Uncyclopedia's articles often begin with quotations, usually misquoted, fictitiously attributed or entirely fabricated.[20] Among the most recurrent themes is the invention of quotes attributed to Oscar Wilde,[2] prompted by an article stating that inventing Wilde quotes was the "national sport of England", and themes such as "kitten huffing" (the inhalation of the souls of cats as a form of drug abuse).[3]
Much like Wikipedia, Uncyclopedia has policies concerning vanity articles, which are articles written by an individual associated with the subject of the page. Vanity articles were disallowed after many of them produced flame wars.[3] Uncyclopedia does not police conflict of interest but may delete submissions as non-notable on a case-by-case basis, using an AfD-like system called "Votes for deletion" (VfD) and a CSD-like system called "QuickVFD".
One of Uncyclopedia's most popular articles,[21] "AAAAAAAAA!", is a nonsensical page, with its content completely consisting of the upper case letter A with images and some punctuation marks.
Site-wide pranks
Some jokes involve the entire website, sometimes including a re-skin of the main page, such as with holiday themes. In 2012, as a parody of Wikipedia's black-out protest against the Stop Online Piracy Act (SOPA) et al., Uncyclopedia blocked all content for a day with a notice claiming to support the bills.[22] A tradition of April Fool's Day front page pranks occurs on the wiki, including a "blood donation" plea banner to spoof wiki donation banners on April 1, 2014.[23] For one week in 2013, the Wikia fork interrupted viewing with a claim that the site was unavailable, spoofing a notice on the NASA website during the United States federal government shutdown of 2013.[24]
Traditions
Each year, Uncyclopedia writers create a list of 100worst reflections of that year, marking website milestones or simply news. Most years, the creators of the list reveal that they have once again put off the list until the last second, and simply skip a large chunk to get to a hundred in time. Other Uncyclopedia traditions include creating a "top10" list of articles for each year, chosen by popular vote.
