- The fact that Wikipedia, almost famous for being so humorless and stuffy, has a Theme Song. It's a parody of "Hotel California". Yes, really.
- Many of the April Fool's Day pranks, as seen here.
- Back in 2005, an administrator accidentally blocked co-founder Jimbo Wales' account indefinitely, then undid the block with an edit summary of "OOPS!" A month later, another admin blocked him for 1 second as a joke.
- The Bad Jokes and Other Deleted Nonsense section was once a relatively popular place to post instances of creative or hilarious article vandalism. Alas, the page was laid to rest in 2007 due to the fact that the page may actually be promoting vandalism, and the page's archives were offloaded to dedicated sites.
- The entire lamest edit wars pages. Internet Backdraft over the most petty (and hilarious) issues shows up here in spades.
- Is it appropriate to include a picture [on the Cow Tipping article] of a cow with the caption "An unsuspecting potential victim"?

- An edit war over what to call Mozart's buttocks! Should the German "Arsch" in the title of a joke composition be translated as "arse" or "ass"?
- This FAC filled with Gratuitous Iambic Pentameter.
- This section of the "Buttered cat paradox" page. Specifically:
In reality, cats do possess the ability to turn themselves right side up in mid-air if they should fall upside-down, known as the cat righting reflex, which enables them to land on their feet if dropped from sufficient height (about 30cm). A similar ability has not been reported for buttered toast.
In reality, cats do possess the ability to turn themselves right side up in mid-air if they should fall upside-down, known as the cat righting reflex, which enables them to land on their feet if dropped from sufficient height (about 30cm). Toast, being an inanimate object, lacks both the ability and the desire to right itself.
- Since that example was added, the part was edited to an even funnier version:
- If you're into Black Comedy, some of the entries in the list of unusual deaths can be darkly humorous.
- Wikipedia has proven itself correct at least once.
- While it's since been edited, one list formerly had a suspiciously specific clarification◊ regarding any additions.
- From the page category "Wikipedia Humor":
This page in a nutshell: Inside a nutshell it's too dark to read this page! Please help me! Grab a nutcracker!
- Deleted Articles With Freaky Titles from The Other Wiki. Highlights include "Angry donkey", "Attack of the fifty foot Hitler", "The cheeses has eats my one friends", and "List Of Dads Who Make Other Dads Eat Bugs", whose discussion page contained "my dad".
- Also, "1933 in Video Gaming" and "All Hail the Yeti".
- 'This page contains material which is kept because it is considered humorous.'
- Not to mention Lamest edit Wars.
- And Unusual Articles
- It's been taken down, but The Other Wiki once had an archive of vandalism they found amusing or clever.
Humorous references to the Douglas Adams novel Mostly Harmless are inappropriate content for this article.
- Someone once altered the page on rapper Chamillionaire to indicate that he had evolved from Charizard.
- They still archive hoax articles that were successful, like Gaius Flavius Antoninus (Supposedly helped assassinate Julius Caesar, lasted 8 years), Olimar the Wondercat (fake TV show about a real-life neurologist and his cat, almost lasted 7 years), and the Bicholim conflict (Fake Indian war that achieved Good Article status and lasted 5 years.)
- More here.
- The Wikipedia page for Earth is often vandalized to read simply "Mostly Harmless."
- From the discussion page for the Earth article:
- An infobox for an illustration of territory in Antarctica claimed by various nations was edited to read "All territorial claims frozen (literally and figuratively)."
- There used to be (it has been taken down since) a Take That in their list of political catch phrases' section about Bill Clinton. It read "'I did not have sexual relations with that woman', said by Bill Clinton regarding Monica Lewinsky, a woman with whom he had sexual relations." The "a woman with whom he had sexual relations" has since been trimmed down, although there's still some implied ones about other politicians ("'Read my lips: no new taxes', said by George H.W. Bush during the 1988 U.S. presidential election. Bush raised taxes later in his presidency.")
- The plot summary of the music video for Jizz in My Pants is classic.
- Wikipedia on the dangers of bee-keeping: "It's worth noting that no amount of protective clothing will make the experience of a faceful of aggressive bees flying up from an opened hive pleasant for any beekeeper".
- A now-suppressed edit (on the grounds of it being "purely disruptive material") of the synopsis of the lyrics to "Baby Got Back" read (according to what can be read on its edit summary): "In this song, Sir Mix-a-Lot quotes Aristotle, in the line 'My anaconda don't want none unless you got buns, hun,' rocketing him into the leagues of Lenn...", before the edit summary's limited number of characters cuts it short. (The "Lenn" was probably refering to "Lennon".)
- Wikimedia, who runs Wikipedia and other affiliated websites, has a classy article about behavior called Don't be a dick. At the bottom of the article, it says: The term "dick" in this essay is generally defined as "an abrasive and inconsiderate person" of any gender. Therefore this is an essay about obnoxious behaviour.
- When a user searches for "The one with the whales", the site redirects to Star Trek IV.
- Similarly, searching for "Janet Jackson's breast" will work as an actual means of searching for their entry for the 2004 Super Bowl halftime show controversy.
- The deletion summary for one of "Mr Diaper"'s creepy photos was "Creepy Mr Diaper; speedy delete".

- Due to an incident where Paraguyan president Fernando Lugo got his photo for two weeks on "In the news", he's reached Memetic Mutation status, including his variation of Godwin's Law and Lugopedia.
- The page "No one cares about your garage band" is delightfully snarky.

- The article on the town of Fucking, Austria can be a joy to read once it gets into things such as sign theft and tourism.
- The specificity and quirkiness of certain article categories can be funny— "Paranormal triangles", "Twin people from the United States", "Robots of Austria", "Mobsters by cause of death", "Unidentified sounds", etc. "Accidental human deaths in Florida" also used to be a category.
- From a page on the Horrible Histories book series:
The book Bloody Scotland drew the ire of the Scottish Separatist Group, who claimed it promoted a "UK centric, anti-Scottish viewpoint of Scottish history". They pointed to a featured haggis recipe: "cook the haggis until it looks like a hedgehog after the fifteenth lorry has run over it".
- The "List of Cetaceans page includes a list of information about whales, with diagrams. Places where diagrams are still required are labelled "Cetacean Needed".
- Wikipedia's article on Disruptive Innovation contains a number of examples on the topic, and the very first one lists Wikipedia itself as disruptive to paper encyclopedias, and goes on to describe how inherently superior Wikipedia is to them.
- The section for real monkeys on Wikipedia's page on the infinite monkey theorem is utterly gold, if not just for the images of a monkey trying to use a typewriter and utterly failing:
...Not only did the monkeys produce nothing but five total pages largely consisting of the letter S, the lead male began by bashing the keyboard with a stone, and the monkeys continued by urinating and defecating on it.
