毛髪有利於動物保暖。

我有一天醒來發現上帝將毛髮植在了我的面頰上，我給它剃了。我次日醒來又發現上帝在我的臉上種了毛髮，我又給它剃了。當我第三天發現上帝再一次把毛髮植在我臉上時，我絕定接受上帝的旨意。我就這樣有了鬍子。

One day, I woke up to find that God had put hair on my face. I shaved it off. The next day, I found that God had put it back on my face, so I shaved it off again. On the third day, when I found that God had put hair back on my face again, I decided to let God have his way. That's why I have a beard.
