The minister was not happy with the constant disturbances he was having during his sermons that he decided to call on old Jonas to help him.
Comes the first Sunday morning he gave Jonas a bowl of cough drops which he was to give to every member who was coughing.
Every time a member coughs Jonas gives the cough drop and then the member leaves the hall. At the end of the service half of the members were gone.
After service the minister calls old Jonas and asked him what he said to the members that made them leave the hall. Old Jonas says, all that I said was 'For cough!'
