Most things were getting stuck in a loop around "Indo-European languages" last time I checked. Someone is definitely playing silly buggers.

I was tempted to see whether I could somehow engineer an all-roads-lead-to-goatse situation, but I couldn't think of a plausible pathway.

Just hijack Philosophy.

Too easy. The idea was to create an entirely plausible pathway of links that nobody could complain about individually (so they wouldn't get reverted) which nonetheless eventually led to http:en.wikipedia.org/wiki/goatse

I mean, create that plausible pathway with philosophy as its root. Since so many articles already lead to philosophy, it's a good starting point.
