人們經常把「豬」拿來罵人。
即使在恐懼狂牛症的今日，罵人豬的比率依然比罵人牛的比率要多很多。
事實上，許多人都知道：豬其實是一種聰明的動物。
而且，隨著各式各樣動物科學研究出爐，似乎愈加凸顯早先豬為人低估的不凡聰明才智。
譬如紐約時報這篇《Pigs Prove to Be Smart, if Not Vain》，就提到大家只知道在《三隻小豬》這個故事裡，小豬們最後以堅固的磚房打敗大野狼，卻不知道在那之後，小豬們還繼續用鏡子優化牠們的家。
We’ve all heard the story of the third Little Pig, who foiled the hyperventilating wolf by building his house out of bricks, rather than with straw or sticks as his brothers had done. Less commonly known is that the pig later improved his home’s safety profile by installingconvex security mirrors at key points along the driveway.
根據紐約時報這篇報導所提及的最新研究顯示，豬其實會照鏡子，並且具有觀察鏡射影像以判斷處境安危的能力。
換言之，以罵人而言，用「牛」、用「狼」，都比用「豬」都要更來得適切。
