A little old lady goes to the doctor and says, "I'm afraid I can’t stop passing wind. Luckily, my farts don’t smell and are always silent. As a matter of fact, I’ve farted twice since I’ve been here in your office, but you didn’t even notice."
The doctor looks at her and says, "OK. I can help you, take these pills and come back next week."
The next week, the lady returns. "Doctor," she says, "I don’t know what you gave me, but now my farts stink."
The doctor smiles and says, "Good, we fixed your sinuses. Now let’s work on your hearing."
