An elderly lady goes into the doctor and tells him - "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, since I've been standing here I must have farted at least 20 times."

"No kidding..." says the doctor with a bit of an upturned nose. The doc says "I've got just the stuff." and gives her some pills. "Here take these for 10 days, then return for a followup appointment."

So she takes the pills and returns 10 later as instructed. Infuriated, she confronted the doctor. "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 nodded, "Great, now that we've your sinuses cleared up, we'll work on your hearing next!"
