The closest I came to this was when I worked for a scientific computer manufacturer, and we delivered a computer to a client. I realized when it booted that the interface driver that had been shipped with the machine was way old. I had written most of it, so I pulled up the file in vi, called back to the shop, and asked them to read me the text of particular subroutines. It was not a pretty sight.
And yes, there were choice words when I got back.
