Re: Let's do the timewarp?
In 1970 a programmer decided to prank the online operations centre. A message appeared on the main console saying "I am a ghost and I have changed your master password" - which his program really had done.
In those days recovering from such a situation was relatively easy - except he had inadvertently put his program in a loop. The main console was inundated with the message being repeated - and each time it had generated a different password.
He was fired next day.
