A pipe burst in a doctor's house. He called a plumber¹. The plumber arrived, unpacked² his tools, did mysterious plumbertype things for a while, and handed the doctor a bill for $600.

一个医生家的水管子裂了，他叫来了一个管钳工人。工人到后，打开工具箱，在管子上弄了几下，别人也搞不清他都做了些什么，然后，就递给了医生一张600美元的帐单。

The doctor exclaimed, "This is ridiculous! I don’t even make that much as a doctor!" The plumber waited for him to finish and quietly said, "Neither did I when I was a doctor.”

医生问:“太可笑了，我做医生也没挣这么多钱啊!”管钳工人等着拿钱时，礼貌地说:“我当医生的时候，也没想到会这样。”
