人们有时称一对互相恩爱的老夫妻为Darby and Joan。例如：

• One summer afternoon we drove to my aunt and uncle's home for tea. They were a real old Darby and Joan — as much in love at eighty as they were at eighteen.
  一个夏日午后，我们开车去姨妈姨夫家喝茶。他俩可真是一对恩爱的老夫妻，八十岁的年纪还像十八岁那样甜甜蜜蜜。

许多人都知道一个专门接待老年人的俱乐部——“德比和乔安俱乐部”。而这个词最早出现于18世纪的一首歌中，德比和乔安是歌曲作者的老板夫妇。
