A little old lady goes to the doctor and says, "I can’t stop passing gas. 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."
"I can help you," says the doc. "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 reek."
The doctor says, "Good, we fixed your sinuses! Now let’s work on your hearing."
