Simon says: Get the facts from Mr. Gradgrind
Yes, that was the Paul Brians talking to Scott Simon this past weekend. The topic was Mr. Gradgrind's Literal Answers to Rhetorical Questions, Paul's site named after the character in Dickens' Hard Times. You can listen in here to find out answers to some of life's most pressing questions: "How high the moon?", "How long has this been going on?", and, of course, "What shall we do with the drunken sailor?"
Many of Paul's other answers are related to questions of English usage. As ever, those can be found in Common Errors in English Usage.
