Assuming each monkey typed a steady 120 characters a minute, mathematicians have calculated it would take 10 <+>813 (10 followed by 813 zeros) monkeys about five years to knock out a decent version of Shakespeare's Sonnet 3, which begins: "Look in thy glass and tell the face thou viewest, Now is the time that face should form another." And that's if they had a computer each.
