An elderly woman goes to the doctor. She says, "Doc, it's terrible, I pass gas all the time. Fortunately, it's odorless and silent, otherwise I'd be mortified. For example, I've passed gas ten times just since we've been talking, but it's odorless and silent so you can't tell."
The doctor gives her some green pills and tells her to take one a day and come back in a week.
The woman comes back after taking the pills for a week. She says, "Doc, there's been a change but not for the better. I still pass gas all the time, but while it's still silent, now it smells terrible!"
The doctor says, "Well, I'm glad we cleared up your sinus blockage, now we'll have to work on your hearing."
