The night before the exam, two students tied one on, and managed to sleep through the final. They agreed to tell the professor that they had a flat tire on the way to the exam.

期末考前一晚，兩個學生喝醉了，考試時呼呼大睡。他們說好，拿車子上學途中爆胎當藉口，向老師求情。

"No problem." said the Professor, "Come by my office at 5 P.M. and I'll give you the exam then."

教授說：「沒關係。下午5時來找我，到時讓你們補考。」

The students spent the intervening time getting information on the exam from students who had already taken it.

兩個學生趕緊趁傍晚之前，向考過的同學打聽試題。

The Professor had given them the exact same exam taken by the class. However, there was an additional page tacked on the end, upon which was written, "For 50% of the grade, which tire was flat?"

教授給他們的補考試題和早上考的一模一樣。不過，考卷最後附加一張紙，上面寫著：「占分數50%，哪個輪胎爆胎？」
