English Original
At a convention of biological scientists, one researcher remarks to another, "Did you know that in our lab we have switched from mice to lawyers for our experiments?"
"Really?" the other replied, "Why did you switch?"
"Well, for five reasons. First, we found that lawyers are far more plentiful. Second, the lab assistants don't get so attached to them. Third, lawyers multiply faster in numbers. Fourth, animal rights groups will not object to their torture. And fifth, there are some things even a rat won't do. There is a drawback, however; sometimes it's very hard to extrapolate the test results to human beings."

在一次生物科学家大会上，一位研究员对另一位说：“你知道吗，我们实验室已经不用老鼠，改用律师来做实验了。”
“真的吗？”另一位答道，“为什么换呢？”
“嗯，有五个原因。第一，我们发现律师数量要多得多。第二，实验室助理不会对他们产生感情。第三，律师数量增长得更快。第四，动物权益组织不会反对折磨他们。第五，有些事情连老鼠都不愿意做。不过，也有个缺点：有时很难将实验结果推及到人类身上。”
