There was a woman who went to a doctor because she had severe farting problem. She said "Doctor, I have a problem. I fart constantly. It's not a big deal because it never smells and it's always silent but I'm worried there may be medical problem." Doctor then examined her and gave her some medication to try. She left and a week later she came back furious. "Doctor, what have you done? Now my fart stinks.", she said. Doctor replied, "Good, now let's fix your hearing."
