Are you being serious? If a bank "locked" its vault by tying the door closed with yarn, would you say "at least they locked it"?

I believe it's a joke referencing the default password for mssql for many years of sa/null. Eventually the install started forcing the user to change it to something, but for a time there were many mssql databases out there with a default password of null.

Oracles default password is change_on_install and you would be surprised at how many DBAs type it every day without reading it...
