检查精子数量（双语对照）
A 70 year old man went to his doctor's office to get a sperm count.
The doctor gave the man a jar and said, "Take this jar home and bring me back a sample tomorrow."
The next day the 70 year old man reappears at the doctor's office and gives him the jar,
which is as clean and empty as on - the previous day.
The doctor asked what happened and the man explains: "Well, doc, it's like this: First I tried with my right hand, but, nothing. Then I tried with-my left hand, but still nothing.
Then I asked my wife for help. She - tried with her right hand, with nothing. Then her left,but nothing. She - even tried with her mouth, first with the teeth in, then with the teeth-out, and still nothing.
We even called up the lady next door and-she tried with both hands and her mouth too, but nothing."
The doctor was shocked! "You asked your neighbor?"
The old man replied, "yep, but no matter what we tried we couldn't get the DARN jar open!"

一个70岁的老人请医生检查他的精子的数量。
医生给他一个瓶子说：“把这个瓶子带回家明天把样本带回来。”
第二天，当老人再次出现在医生面前的时候带给医生的还是一个和先前一样的空空如也的瓶子。
老人解释说：“医生，是这样的。我先用我的右手弄，不行，改用左手还是不行，于是找我太太帮忙，她也用了她的左手和右手，还用了嘴巴，甚至用牙齿咬来咬去，仍然不行。没办法，只好找来隔壁的女士帮忙，她也用了手和嘴巴，结果都不行。”
医生震惊了！“你还找你的邻居帮忙了？？”
老人回答说：“是啊。可是无论我们用什么方法都不能把这该死的瓶子打开！”(※本文转自：华师后院http://www.myscnu.com)
