Circularity

xkcd explains how a fake entry in Wikipedia gets repeated elsewhere then cited as support for the fake entry. There is, you might guess, a Wikipedia page on this phenomenon, although it does not cite xkcd. It does, however, cite an article just published on the subject. This article links and cites the Wikipedia page on the phenomenon.

I really want that to be a prank at a higher level of recursion.

I would also like to note that “circular reference” references circular reporting, which references circular reference. Disappointingly, self-reference does not reference itself.
