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. 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. You didnt know I was farting because they dont 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 goes back. Doctor, she says, I dont know what the hell 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.
