The problem has been in existence long before 1978. In particular, I had learned it in 1986 from a friend who had known it for another 5 to 10 years from the Odessa, USSR math olympiad circles. In fact, he first told me the safe sex version of it and immediately added: ''But, of course, the Olympiad people phrazed it in the surgeon form for decency reasons. ". i am sure, there is somebody from Odessa who can trace how the problem got to Odessa in the first place. I would not be surprized if it were more than 30 years old and had appeared in some earlier puzzle book. --Vlad
