A woman goes to the doctor and tells him: "I got a horrible
problem with gas, but luckly when I pass gas it doesn't make
any noise and it doesn't smell. In fact I have passed gas
several times since I've come into your office."
The doctor gives her some pills and tells her to return in
three days. When the woman returns she tells the doctor:
"I don't know what those pills were but I still have gas and
it's still silent but now the odor is terrible!"
And the doctor says: "Now that we've cleared your sinuses
lets work on your hearing."
