This old lady goes to see her doctor and says, "Doctor, I've got an annoying problem but I guess it's not too serious. You see, I've got a farting problem. They're silent and they don't smell bad. I wouldn't even be here asking for help if they didn't come so frequently. I've been here 5 minutes and I must have farted like 20 times but you don't know that because you can't hear it and they're oderless." The doctor ponders a bit and then scribbles a prescription. He says, "take this once a day for a week and then come see me." The old lady comes back a week later and says, "DOCTOR, what did you do?!?!" You didn't cure my farting problem; you made it worse! Now it smells terrible!!! To that the doctor says, "Ah, I see we've taken care of your sinuses. Now we have to take care of your hearing."
