As of September 14 2005, a search at google for the following phrases yield no results:
Reboot the Robot Jesus
Hannah yammers for clams in Kansas
Harmony decries the sullen sunrise
Wake me when we reach the singularity
The phrase "ungoogled phrases" also yields no results.
So later if these phrases show up in a google search we can assume all the results are wikipedia mirrors, assuming user subpages show up on mirrors. This is one way of getting a list of mirror sites, which may or may not be useful for something.
