If you're not already acquainted - nay, infatuated - with the works of the man who the New York Times calls "the funniest man in America, " you can get cracking right now with this all-time favorite collection of Dave Barry's humor columns. "Dave Barry's Bad Habits" won't rot your teeth, cause your insurance premiums to go up, or make your kids go cross-eyed if they sit too close to it. It will, however, make you laugh so hard your middle actually moves (the best exercise, and possibly the only kind you'll be interested in after forty). Here, preserved for all time, are Barry's profoundest musings on such topics as how to get kids to stop smoking (eliminate tenth grade), what to do if your car is making loud noises (turn up the radio), and a solution to the battle of the sexes (let the men do housework, say, for the next ten thousand years to even things up). Together they serve to expose the little insanities of everyday life and assure us that we're not completely alone in a world gone mad.
