This is a little off-topic, but related...
Aeons ago (I had hair) we were attempting to get a Sun 3/60c talking to a Vax 11/785, we were steadily climbing our way up the chain, towards the end of the 'process' the 3/60c put this on the screen:
"Are you sure you really know what you are doing?", clearly we didn't, well not for a while anyway, so we took the message as a hint that we should go to the pub.
After lunch it shared this gem: "I am not entirely sure what you are looking for, but I am pretty sure it's not out there..."
Memory may have failed a bit (it was ~28 years ago), still makes me giggle, mmdv.
