A professor at the Michigan State University was known for giving boring, cliche-ridden lectures.  

At the beginning of one semester, an innovative class breathed new life into the course by assigning baseball plays to each hackneyed phrase.  

For example, when the professor said, "On the other hand," that counted as a base hit. "By the same token" was a strike out; "and so on" counted as a stolen base. Divided into two teams by the center aisle of the lecture hall, the students played inning after inning of silent but vigorous baseball.  

On the last day of class, the impossible happened: the score was tied and bases were loaded. Then the batter hit a homerun! The winning team stood and cheered wildly.  

Though deeply appreciative, the professor later was quoted as wondering why only half of the students had been enthusiastic about his lectures.
