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. My farts never smell and
are always silent. As a matter of fact, I've farted at least twenty times since
I've been here in your office. You didn't know I was farting because they don't
smell and are silent."
doctor says, "I see, take these pills and come back to see me next week."

know what the heck you gave me, but now my farts, although still silent, stink
doctor says, "Good, now that we've cleared up your sinuses, let's work
on your hearing."
