An old lady came into her doctor's office and confessed to an
embarrassing problem: "I have gas all the time, Doctor Johnson, but they're soundless, and they have no odor. In fact, since I've been here, I've passed gas no less than twenty times. What can I do?"

"Here's a prescription, Mrs. Barker. Take these pills three times a day for seven days and come back and see me
in a week." said Dr. Johnson.

The next week, an upset Mrs. Barker marched into Dr.Johnson's office:"Doctor,I don't know what was in those pills, but the problem is worse! I'm passing gas just as much, and
they're still soundless, but now they smell terrible! What do you have to say for yourself?"

"Calm down, Mrs. Barker," said the doctor soothingly. "Now that we've fixed your sinuses, we'll work on your hearing."
