An old woman goes to the doctor to complain about her flatulance.

She tells the doctor that although her farts were silent they stank and would like to do something about it. The doctor gave her some pills and told her to come back in two weeks time.
Two weeks later she came back and told the doctor: Doctor, my problem is a lot worse now. Not only do my farts still stink but they're as loud as hell. The doctor says: well, now that you got your hearing back let's see what we can do.
