My dad has a story he likes to tell about one of his friends, a scientist. The scientist was giving a lecture in Japan, and opened with a joke that lasted a couple minutes. After delivering the joke in English, he waited for his translator to relay it to the audience. The translator spoke for only a few seconds, and then the crowd burst out laughing.
After the presentation was over, the scientist asked the translator how she managed to distill the humor of his joke down into such a concise form.
