A little old lady goes to the doctor and says, "Doctor I have this
problem with wind, but it really doesn't bother me too much. They never
smell and are always silent. As a matter of fact, I've farted at least
20 times since I've been here in your office. You didn't know I was
farting because they don't smell and are silent."

The doctor says, "I see, take these pills and come back to see me next
week."

The next week the lady goes back. "Doctor," she says, "I don't know
what the hell you gave me, but now my farts... although still
silent... stink terribly."

"Good!" the doctor says, "Now that we've cleared up your sinuses,
let's work on your hearing."
