An elderly lady goes into the doctor.

"Doctor, I don't know what the problem is, but I've been farting all the time. It's not really a problem socially because they don't make any noise and don't smell. I just can't stop farting all the time. In fact, while I've been in here I must have farted at least 20 times."

The doctor nods and gives her some pills. "Here take these for two weeks and come see me again when you are done."

So she takes the pills and returns two weeks later as instructed.

The lady is very angry. "What kind of medicine is this? I'm still farting just as much. They still don't make any noise, but now they stink terribly!"

The doctor nods, "It's alright, now that we have your sinuses cleared up, we'll work on your hearing!"
