And good luck contributing edits to controversial topics (i.e. anything related to the big topics like the Middle East, religion, Pokemon etc.) where the same battles are fought over and over and over again in a war of attrition. The price of victory is eternal vigilance and an endless supply of fresh troops to reinforce your position.
It's controversial because people get into arguments about it. He included it in the list because it's also trivial and silly, as a way of saying that Wikipedians get into arguments about trivial and silly things ( http://en.wikipedia.org/wiki/WP:LAME ). It's a joke of sorts.
There's Keldeo, Meloetta, and Genesect - the missing Pokemon. They are only present on a Nintendo game, and only if you hack it. But they are vaporized, 1984-style, from the English Wikipedia; as they don't exist in the real Pokemon world.
