In The Exam Hall :
The student asked to examiner,
"Do you know who I am?"; The examiner said, "No and I don't care."; The student asked again, "Are you sure you don't know who I am?"; The examiner again said no. So the student walked over to the pile of tests,
placed his inthe middle,
then threw the papers in the air. "Good" the student said, and walked out. He passed.
