xkcd:
Wikipedia trivia: if you take any article, click on the first link in the article text not in parentheses or italics, and then repeat, you will eventually end up at “Philosophy”.
I had to request semi-protection for the XKCD article and get someone blocked for twelve hours because people kept going in and changing the first link to point to ‘philosophy’.
Also, Wikipedia knew about this before xkcd. See Wikipedia:Get to Philosophy.
