I just went out to a book store and there I happened to find a book note with an interesting cover, like a page of comic. There is a short dialog between a teacher and his student in it.
Student: Sir, I have a question.
Teacher: What is it?
Student: Will you be angry for something we haven’t done, Sir?
Teacher: Of course not :)
Student: Oh, thank you Sir. We actually haven’t done the homework.
Kocak .. lol
