请教一则英语笑话的意思.
Confiding in a co-worker,I told her about a problem in our office and my fear that I would lose my job.She was concerned and said she would pray for me.I know she keeps a list of the ten people she believes need her prayers the most,so I asked if she had room for me on her list."Oh,yes," she replied."Three of the people have died."

答案

在一次与同事吐露心事的时候,我告诉了她我们办公室的一件事以及我可能因此而失去工作的担忧.她很关心地说她会为我祈祷.我知道对于哪十个人最需要她的祈祷,她心里有谱,于是我问她是否我也在其中.“哦,是的”,她回答说,“其中三个已经死啦.”
就是说,我之所以可以列入被祈佑的名单是因为有人死了,而死的人正因为受到她的祈佑,她的祈祷成为诅咒,甚至也许是因为她搞的鬼.所以暗示着我可能也不会幸免.
