Joy Tears

 Cudgeling their brains to answer the questions in the final exam, students look every now and then in their watches to see the remaining time. All of a sudden a student burst into tears breaking up the hushed silence in the exam room. Some  students thought she was paining and could not help hold the cry. Feeling pity, students called for a emergency doctor. Everybody dropped their pens and asked the ailing student: "What's up?" "How are you doing now?"

Feeling embarrassed, the student said, "I am so happy. I have never thought that the exam would be answered within 90 minutes. It is joy tears!"

"What?!" said all students in one go. You have wasted our precious time for this! Finally, they called for extra time.
