Farts!!!

A little old lady goes to the doctor and says, "Doctor I have this
problem with gas, but it really doesn't bother me too much. My farts
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 comes back.
"Doctor," she says, "I don't know what the hell you gave me, but now
my farts... although still silent... stink terribly."

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