A woman goes to her doctor next door and tell him the problems she's been having.

"Doctor, I've been having troubles with my farts, they're silent and have no smell."

"That's weird, here, take these pills and come back in a week and tell me if they worked".

So the woman takes the pills, twice a day, for a whole week, and then returns to the doctor a week later.

"Doctor, the pills you gave me are worse!"

"How come?" asks the doctor?

"Well, my farts are loud now, but they still have no smell".

"Good, now that we've unblocked your ears, let's get you some pills to clear up your nose".
