晚上，福尔摩斯和华生宿营在外，美丽的星空下他们支好了帐篷。半夜，福尔摩斯把华生推醒，问华生：“看天上的星星，告诉我你看到了什么？”华生半梦半醒：“成千上万的星星罗。“福尔摩斯又问：“那你的推理？”回答是：“嗯，成千上万的星星，那么很可能存在着与地球一样的星球，嗯，说不定那儿也存在着生命。”福尔摩斯一声叹息：“华生，这说明我们的账篷被偷了！”
其实我更喜欢英文版的= =
Sherlock Holmes and Doctor Watson went camping in a mountainous area. They were lying in the open air under the stars. Sherlock Holmes looked up at the stars and whispered, "Watson, when you look at that beautiful sky, what do you think of?" Watson replied, "I think of how short life is and how long the universe has lasted." "No, no, Watson!" Holmes said. "What do you really think of?." Watson tried again. "I think of how small I am and how vast the sky is." "Try again, Watson!" said Holmes. Watson tried a third time. "I think of how cold the universe is and how warm people can be in their beds." Holmes said, "Watson, you fool! You should be thinking that someone has stolen our tent!"
