Here's a fun little project that puts that old XKCD comic to test: Repeatedly navigating to the first non-parentheses non-italics link in a wikipedia article will eventually lead you to Philosophy. It starts at a random article (but you can totally choose its starting point by changing line 64.
When I hand-tested this myself many years ago when I should've been paying attention in school, it definitely worked. Sadly, it seems to no longer be the case - although now, it seems as though all articles eventually lead to Mathematics... which I suppose also works.

@nicholaschorett: It has no real, meaningful purpose. However, it is a funny reference to XKCD, a popular web comic, and it tests a rather old joke/piece of trivia. So in the grand scheme of things, there is no point, but if you're a fan of XKCD or just computer-based jokes and "tech" culture in general it may be of some relevance and/or interest.
