A cute 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. It never smells and is
always silent. As a matter of fact I've farted at least
10 times since I've been here in your office. You
didn't know I was farting because it doesn't smell
and is silent."
The doctor says,
"I see. Take these pills and come back to see me next
week".
The next week the lady returns.
"Doctor," she says, "I don't know what
the heck you gave me, but now my farts, although still
silent, stink terribly".
"Good," the doctor said. "Now that we've
cleared up your sinuses, let's work on your
hearing."
