Mrs Smith is a hypochondriac and her doctor — fed up with her constant complaints about non–existent illnesses — starts palming her off with a mild sedative to keep her happy. One day Mrs Smith complains of chest pains and is prescribed her usual treatment. However, this time the pain is real and Mrs Smith dies of a heart attack. The doctor hears this and is so upset he dies of shock. Mrs Smith and the doctor are buried in adjoining plots. Next morning, the doctor hears a tapping on his coffin. A muffled voice calls out, 'Doctor, this is Mrs Smith! Do you have anything for worms?'
