I've given a hint on another site and to be fair I'm adding it here; Its from a book by a well known author and published more than 30 years ago and is science fiction. I'm thinking that if you've read it the reference should jump right out at you. I read it in the 80's and it made enough of an impression that I still remember it after reading it that long ago. I've also not seen it repeated anywhere else.
