Joke: "The Cough"

My husband caught a cold these days and coughed badly. His wife came to give him the medicine to take.

Husband said: I cough to take the medicine can make good?

Wife said guarantee works! The husband came home in the evening, and the wife asked him how was the effect?

Husband said it really works, cough, pull a trouser pocket, cough, pull a trouser pocket, scared are afraid to cough...
