Puzzled, the doctor begins to examine the old woman. He listens to her breathing, checks her sinuses and blood pressure, looks at her throat and then sits down at his desk. "Well," he says, "I'm glad you came to see me when you did. Here are some pills I want you take twice a day. Come back and see me in a week to let me know how you're doing."
The old woman thanks the doctor and leaves, then returns a week later. "Doctor, those pills didn't work at all--In fact, they made things worse! I'm still farting just as often, but now they really stink!"
The doctor said, "Well, it looks like we've got your sinuses sorted
out. Now we can work on your hearing."
