Neal Stephenson, answering the question:
"In a fight between you and William Gibson, who would win?"
"Neal: You don't have to settle for mere idle speculation. Let me tell you how it came out on the three occasions when we did fight."
(Also, more seriously, contains a great quote on self-defense in faraway places:
"The best 'self-defense means' when you are surrounded by a hundred million people of some other culture is to avoid dangerous places and figure out some way to get along with the folks around you."
Words to live by, say I.)
