The woman replies, "This is very embarassing, Doctor, but I have a flatulence problem. I fart all the time. In fact, since you've been here in the room, I have farted at least twenty times. But fortunately, they are silent and odorless."
"I see," said the doctor, "I have just the thing for you. Take these pills twice a day for two weeks and come back for a return visit."
Two weeks later the woman returns for her appointment. She says to the doctor, "I don't know what you gave me, but those pills made things worse! Now my farts stink to high heaven!!"
The doctor says, "Good! Now that we have solved your sinus problem, we're going to work on your hearing."
