A women goes to the doctor complaining of her constant flatulance. She says, "Doctor, I must fart 500 times a day, BUT you would never know it, because they’re SILENT and the don’t SMELL! For instance, I’ve just passed gas at least 20 times just sitting here with you right now!"
The Doctor just nods and gives her a prescription. He tells her to come back in 2 weeks.
2 weeks later she enters his office and says: "Those pills made my farting worse! I’m still breaking wind 500 times day, but now they SMELL REALLY BAD!
The doctor replies: "Well, now that we’ve cleared up your sinuses, we can work on your hearing!"
