A lady goes to the doctor complaining of severe flatuance.

Lady: Doctor you have to help me, I fart constantly, one after another.
      They don't smell or make noise but its still embarrassing,
      in fact I've farted more than 20 times since I've been here!

Doc:  OK calm down, take these pills and come back in a week.

One week later...

Lady: Doctor its worse than ever!  I fart just as much but now they smell!

Doc:  Good! Now that your sense of smell is back we'll work on your hearing.
