I found this article that claims that Microsoft had a spy inside Apple whose mission was to steal Mac OS 10.2 source code and deliver it to Mr Gates.
It seems Apple security found out, and by orders of Steve Jobs they set the spy up with the 'code' of 10.2 which in reality was System 7 written in this weird and complicated language called INTERCAL. Apparently it was a joke but Microsoft spent various years decoding the code only to find out very late the true nature of it... this is told my a MS employee responsible for such things... Here is the link.
