My favorite example of that was a while ago, "vixie-cron will read a cron stanza from a core dump written to /etc/cron.d" when you could convince it to write a core dump there. The other crons wouldn't touch that, but vixie-cron happily chomped through the core dump for "* * * * * root chmod u+s /tmp/uhoh" etc.
