“ Miltons were, on the whole, the most enthusiastic poet followers. A flick through the London telephone directory would yield about four thousand John Miltons, two thousand William Blakes, a thousand or so Samuel Colleridges, five hundred Percy Shelleys, the same of Wordsworth and Keats, and a handful of Drydens. Such mass name-changing could have problems in law enforcement. Following an incident in a pub where the assailant, victim, witness, landlord, arresting officer and judge had all been called Alfred Tennyson, a law had been passed compelling each namesake to carry a registration number tattooed behind the ear. It hadn't been well received--few really practical law-enforcement measures ever are. ”
