How to \'implements\' a joke during a presentation

How to "implements" a joke during a presentation 

文/剿匪出關

"implements" 是Java的一個關鍵詞。我寫習慣了，以至於在昨天講座的slides中，出現了"to implements"的語法錯誤，而Latex的Beamer並不能查語法錯誤。

當時有點尷尬。但我馬上笑道：“Please execuse my English. In my first semester of teaching, I gave students extra credit for pointing out grammar erros in my slides. In the second semeter, I cannot do it anymore. The students asked why? I said I cannot just let everybody get A。”

哄堂大笑！
