The lecturer on evolution had been going on for nearly two hours. Then he started again, and said he: Let me ask the evolutionist a questionif we had tails like a baboon, where are they?

　　I'll venture an answer, said an old lady. We have worn them off sitting here so long.

　　教进化论的老师已经滔滔不绝地讲了快两个小时，他的话题又来了：让我向进化论者提个问题如果我们曾经像狒狒那样长着尾巴，那么现在尾巴到哪里去了?

　　我来试试看，一位老太太说。该是我们在这里坐这么久把它们磨掉了吧。
