Here's a fun drinking game for you: take a shot every time you discover a VM in your environment named "test-server," "idk-what-this-does," or "IMPORTANT-DO-NOT-DELETE" that for some reason is running a production workload nobody wants to touch anymore. OK, actually don't do that - you'll need to be sober when the inevitable happens and one of those mystery VMs goes down, taking an entire half of the company's operations with it.
