" When he was a boy he'd read books about great military campaigns, and visited the museums and looked with patriotic pride at the paintings of famous cavalry charges, last stands and glorious victories. It had come as rather a shock, when he later began to participate in some of these, to find that the painters had unaccountably left out the intestines. Perhaps they just weren't very good at them. "
