nis table admin -fuckit
Over 20 years back a colleague of mine managed to demote a NIS+ server with a single command meaning there was no master left or something like that.
Neither we on the project nor Sun support could find any way back - so we rebuilt around 20 sun machines from scratch over the next 24 hours...
Our customer rephrased whatever the actual command was to that in the title - seemed appropriate then and I still remember it now!
