Nikola Tesla

Born of Serbian parents in a part of Austria-Hungary which is now in Croatia; so was he Serbian? Croatian? Austro-Hungarian? You decide! But don't forget to leave an edit summary saying how pathetic it is to choose any other version...

Her Late Majesty

Must a queen deceased for over a century still be styled here "Her Majesty", an epithet conventionally reserved for the current monarch? This weighty dispute (pale reflection of warring here), filling talk pages and edit histories, has spilled over into other British monarchs, other royals and titleholders, several countries having or having had a monarchy, claimants and other royal pretensions, and even hundreds of holders of the papacy, where popes centuries dead are endorsed as “His Holiness” here, losing and regaining the endorsement with blinks of eyes. Ongoing debates deal with the format of dates, and the used or unused, existing or non-existent surnames family names house names former fiefs (some inherited names, but very few are sure what they precisely are) of monarchs and relatively unfamiliar variants of those (as well as the putative name of the horse of her late majesty's husband's family), with most edits being extremely trivial. Involved parties vouch for only aiming at accuracy, and certainly some argumentation goes deeper than believed humanly possible. This even created an edit war over whether it could be mentioned here. A truce, seemingly imposed by a Royal intervention that dragged in innocent bystander Prince Michael of Kent, Scottish accents and snail slime, appears to be holding, though occasionally some new fallout is being generated.

e (mathematical constant)

An editor who self-admittedly knows little of mathematics disputes the status of e as an "important number", preferring the term "special number". When a number of mathematically inclined people disagree, he argues that e is not in fact a number.

Orange (colour)

A cut-and-paste move to the American spelling "color". A move back, and statements that Canada, Australia, and the rest of the colour-spelling world didn't matter because the United States spelled it color. Other attempts follow, with one attempt to move it to simply Orange to end the war.

Beelzebub

Edit war in December 2005 over whether the picture at the top should be on the left and face left, or be on the right and face left, or be on the left and face right, or be on the right and face right. Image was eventually replaced with a higher quality version.

Missionary position

A revert war between two versions of the line drawn illustration, one incorporating a teddy bear and one without. Some people claimed the bear was distracting, or believed it implied the woman to be under age. Other people found the bear adding atmosphere since the couple is ignoring it.

Cranky Kong

Was Cranky Kong the original Donkey Kong? Could it be the character in Super Nintendo and Nintendo 64 games is actually his son? Or perhaps his grandson? Should we trust offhand comments made by a video-game character? Does being licensed by Nintendo make Rareware publications "official"? How official is the "Nintendo Seal of Quality"? To some people, these questions are a matter of life and death.

List of numbers that are always odd

The number 3 was being considered as possibly being not odd. Page protection was needed to halt the heated debate. User:Wik's correction of a misspelling of hypochondriacs was re-reverted no less than 3 times. Supposedly as a means to illustrate the ludicrousness of the subject, various examples such as "the atomic numbers of gold and silver, but not their sum" and "the number of days in a year (except leap years)" were added to the list. Later in the edit war, no less than two thousand five hundred numbers of debated oddness (every second integer from 1 to 4999) were added and removed, four hundred ninety eight of them repeatedly before the edit war was solved by the article's deletion after a VfD vote. An ancient mirror out on the Net still had a version available, though, so it's been rescued for posterity: User:ConMan/List of numbers that are always odd.

List of virgins

Dispute about whether or not Britney Spears belonged on the list, eventually resolved in a definitive manner. Eventually maintenance of the list proved impossible and it was deleted.

WNRI

Should we mention the fact that the station's broadcast power drops to a ridiculously low wattage at night? Yes, it's a fact. No, I could LOSE MY JOB.

Cauliflower

Is cauliflower nutritious? Is specifying what parts are usable POV?

Grace Kelly and Cher

Edit wars over whether each is a gay icon.

Wikipedia:Lamest edit wars ever

Edit wars over which edit wars are allowed to be on this page, or over how specific entries on this page should be worded (oh, the irony). See Recursion; see also tail recursion. Examples have included William of Orange, Her Late Majesty, List of virgins, Template:User admins ignoring policy and this entry itself. These have also resulted in two attempts at VfD (now WP:MFD), which were soundly rejected.
