A little old lady goes to the doctor and says, Doctor, I have this
problem with gas, but it really doesnt bother me too much because
they never smell and are always silent. As a matter of fact, Ive
farted at least 20 times since Ive been here in your office.

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

The next week the lady goes back to his office. Doctor, she says, I
dont know what you gave me, but now my farts, although still silent,
stink terribly!

The doctor says, Good, Now that weve cleared up your sinuses, lets
work on your hearing.
