A little old lady goes to the doctor ... and says, "Doctor, I have this problem with gas, but it doesn't really bother me too much. They never smell and are always silent. As a matter of fact, I've farted at least 20 times since I've been here in your office. You didn't know I was farting because they don't smell and are silent." The doctor says, "I see. Here's a prescription. Take these pills 3 times a day for seven days and come back to see me next week." The next week the lady goes back. "Doctor," she says, "I don't know what the hell you gave me, but now my farts ... although still silent... stink terribly." The doctor says, "Good! Now that we've cleared up your sinuses, let's start working on your hearing."

有位小老太太去看醫生：“醫生，我有愛放屁的毛病。其實也不是大問題，只是我放屁不臭而且沒聲音。事實上，我在這里已經放了20多個屁，但是你并不知道對吧，因為我的屁不臭，而且還沒聲音。”醫生說：“好的，我明白了。吃這個藥片，一天三次連續吃七天，下星期你再來。”一星期后老太太來了，“醫生，你到底給的我什么藥，現在我放屁還是沒聲音，但是怎么這么臭！”醫生說：“太好了！你的嗅覺正常了，現在開始治聽覺。”
