A little old lady is suffering with gas problems. Just lately she finds that she just can’t stop farting.
So, she makes an appointment to see the doctor, and says to him, “Doctor I have this terrible problem with gas, I just can’t seem to stop farting. They never smell, and are always silent, but it’s still a problem all the same. I keep farting all the time, and believe it or not I have farted at least 20 times since I’ve been here in your office!”
The doctor says to her, “I see. Why don’t you take these pills, and come back to see me next week to let me know how you get on.”
So, the next week the little old lady comes back. “Doctor,” she says, “I don’t know what the heck you gave me, but now my farts stink terribly!”
The doctor says to her, “That’s good! Well now that we have been able to clear up your sinuses, let’s work on improving your hearing.”
