Leonard: Why do I bother talking to you people?

Bernadette: That’s not the same thing.
Version 1:
霍沃德：我只不过想让他尝尝自己种下的恶果罢了。
伯纳黛特：这不一样。
Version 2:
霍沃德：我只不过以其人之道还至其人之身而已。
伯纳黛特：这不一样。
This dialogue happens when Howard told Bernadette that he had done something mean to Sheldon, Bernadette didn’t agree with his way, she wanted to persuade him to consider their friendship and Sheldon’s feelings.“have a little taste of his own medicine”is corresponding to the Chinese expression“以其人之道还至其人之身”。Version 1 expresses the original meaning with indicative words, but for most readers, they are very familiar with the proverb “以其人之道还至其人之身”, and its expressive effects are better. To correspond to the target culture, version 2 is more felicitous.
