here is one of my fav jokes-

teacher- students,as a part of literary week celebrations, we have decided to hold a competition!

(children starts to look at each other and whisper)

teacher- silence! the contest is, each day you have to read a well known book! and i'll say the names of some well-known books,and those who have read it should raise their hands, and the one who has read most books,will get extra recess time

(children cheers!later at the end of the week)

teacher- how many of you read , hamlet?

(the whole class raise their hands!)

teacher-good! now how many has read oddissi?

(again the whole class raise their hands!the teacher is suspicious whether they r lying,so she decides to test them)

teacher- exellent!now how many of you have read the biography of aristotile?

(as expected,the whole class raise their hands again!)

teacher- good,but may i inform you that there is no book yet,called biography of aristotle?
