This video is fantastic. If we open a wikipedia page and click on the first link (ignoring language or IPA links) over and over, we have a 97% chance to eventually reach Philosophy. Unfortunately, this kind of changed recently because 25% of pages will reach Awareness, and that used to lead to Philosophy, but it now leads to Psychology. But because we can go from Philosophy to Awareness, I guess that now means 97% of the time we'll reach Awareness?

Funnily enough, there's a heated discussion about this in wikipedia, which is in the realm of talks of wikipedia pages (I've never read these). This is all very fun (did I mention the video is fantastic?).
