It would go something like this:
Imagine a web page paradox.html that has a link to every web page that
doesn't link to itself. Does paradox.html link to itself? If not, then it
should be included on the page in which case it does link to itself. If it
does link to itself, then it shouldn't be on the page in which case it
doesn't link to itself.
