For me, my high bar that I have yet to beat, was the time I pivoted the running OS (ubuntu) into RAM over SSH so I could unmount and image the boot drive without rebooting and loading a live USB (Which would have required a ticket with my provider to enable IPMI)
Ubuntu like 10 years ago, drop to terminal (Ctrl+Alt+F5 or something),
vlc video.mp4Aand it started playing it with ASCII graphics. Magic
