"I remembered the time I was in my fraternity house at MIT when the idea came into my head completely out of the blue that my grandmother was dead. Right after that, there was a telephone call, just like that. It was for Pete Bernays--my grandmother wasn't dead. So I remembered that, just in case somebody told me a story that ended the other way." -- Richard Feynman, "Surely You're Joking, Mr Feynman"
