The Wikipedia Paradox: what's the most notable subject that's not notable enough for Wikipedia?

Now, one could reasonably argue that merely being the answer to this question would not, by itself, be enough to make a subject notable. However, the act of arguing this point, if seriously engaged in by enough people, would, in fact, make the question (and the answer) notable, and thus the answer to the question would deserve inclusion in Wikipedia.

Inductively, you can use this argument to show every subject is notable enough for inclusion in Wikipedia. Take that, deletionists!
