Click the first link on a Wikipedia page. Repeat. Eventually, you'll end up on "Philosophy"

Try it for yourself, or make it into a game with a friend: both of you can choose the starting page that the other person will use. Whoever gets to Philosophy the most quickly wins. I played this with my friend and had her start on Toast sandwich, which led to Philosophy eventually. We discovered that anal beads is one of the few pages that gets stuck in a loop.

"Clicking on the first link in the main text of an English Wikipedia article, and then repeating the process for subsequent articles, usually leads to the Philosophy article. In February 2016, this was true for 97% of all articles in Wikipedia, an increase from 94.52% in 2011. The remaining articles lead to an article without any outgoing wikilinks, to pages that do not exist, or get stuck in loops."
