This little old lady goes to the doctor and says,
“Doctor, I have this problem with passing gas, but it really doesn’t bother me too much. It never smells, and it’s always silent.
As a matter of fact, I’ve passed gas at least 20 times since I’ve been here in your office. You didn’t know I was passing gas, because it doesn’t smell, and it’s 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 you gave me, but now my passing gas, although still silent, it stinks terribly.”
“Good”, the doctor said,
“now that we’ve cleared up your sinuses, we’ll start to work on your hearing.”
