I was called in recently to fix a system to which someone had done `chown -R 777 *` from `/`. So everything was owned by a nonexistent user. It was interesting to fix. Especially since someone had been mucking around trying to fix it from the open root prompt after the damage was done. (mount filesystem from live cd, copy ownership from livecd filesystem to the disk, reboot)
