An elderly lady went to see a doctor. The nurse took her into the examining room, and the doctor came in and asked her what was wrong.

The elderly lady replied, "Doctor, I have this terrible case of gas. Can't seem to get rid of it. There are only two saving graces in this situation - when I break wind it's silent and doesn't really smell."

The doctor nods sagely, takes a bottle from one of his cabinets, gives it to the elderly lady and says, "Please take one of these each day for the next 6 days. Come back for an appointment same time next week."

The elderly lady returned to the doctor's office a week later, and snapped at him when he entered the examining room: "Doctor! That stuff was TERRIBLE. Before I took those pills, it hardly smelled at all when I broke wind, now it stinks so bad that the dog whimpers and slinks away. Thank goodness that it's still silent or I would be perennially embarassed! What have you done to me?"

The doctor smiles, nods and says, "Excellent! I see that we've cleared up your sinus infection. Now let's see what we can do about the hearing loss."
