jrr wrote a Greasemonkey script called de-norris hudson that performs client-side removal of ChuckNorris.
It is said that shortly after Chuck Norris wrote a RoundhouseKick script called de-jrr world that performs a complete removal of jrr. Obviously, nobody has ever seen jrr since.
BTW, thanks to Fabrizio that is always a source of inspiration, we're using the Chuck Norris plugin too.
