A Medicine to Strengthen the Cough

A patient came to a doctor and complained of the weakness of his hearing — to the point that he could not hear his cough when he coughed.

The doctor said to him: No matter, I shall give you an effective remedy. The patient brightened and said: It strengthens the sense of hearing? Said the doctor: No — but it will make you cough a cough so loud that you will hear it.
