One of my favorite teachers at Southeast Missouri State University in Cape Girardeau is known for his droll sense of humor. Explaining his ground rules to one freshman class, he said, "Now I know my lectures can often be dry and boring, so I don't mind if you look at your watches during class. I do, however, object to your pounding them on the desk to make sure they're running!" 在开普吉拉多市的东南密苏里州立大学上学的时候，我喜欢的几个老师之中有一个以他的幽默感而出名。给新生上头一节课，他给学生解释在他课上的纪律，他说：“我知道我的课经常会很枯燥乏味，所以我并不介意你们在课上看表。然而，我坚决不允许你们把表重重的摔在课桌上，以此来检查你的表是不是还在走。”
