Book excerpt: If you've ever had a dentist's finger in your mouth or a doctor's finger somewhere else, you may have wondered about the person behind the knuckle. Now's your opportunity to find out: what it takes to get into medical and dental school and what kind of antics they get up to when training; how they train; what sort of people doctors and dentists are; why they chose the career they do; what the perils and perks are of the job are; and whether they are laughing with us or at us. Check it out in Dr Ray Lowry's book. Ray Lowry started out as a comedy writer for television and radio. Running out of funny material he became a doctor and a dentist. Forty years later he has enough comedy to fill a book, entertain audiences on the after-dinner and comedy circuit and in his newspaper column. Dr Lowry is a truly holistic practitioner (mainly interested in holes) and he has often been up before the General Medical and Dental Councils (they are both late-sleepers). Find out what it is like to be doctor and dentist: the perils and the pleasures, the tears and the laughter. Lie down, open wide and let the laughter out. Anything else and you are in deep trouble.
