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."

有位小老太太去看医生：“医生，我有爱放屁的毛病。其实也不是大问题，只是我放屁不臭而且没声音。
事实上，我在这里已经放了20多个屁，但是你并不知道对吧，因为我的屁不臭，而且还没声音。”
医生说：“好的，我明白了。吃这个药片，一天三次连续吃七天，下星期你再来。”
一星期后老太太来了，“医生，你到底给的我什么药，现在我放屁还是没声音，但是怎么这么臭！”
医生说：“太好了！你的嗅觉正常了，现在开始治听觉。”
