Funny exam answers!

Everyone takes exams seriously. Some depend on a good result in order to achieve their goals. Others, however, are not worried or are just funny and naive. So what does someone write when he does not know the answer to the exam question. I have heard that it is best to write something, even if its wrong, than to give a blank paper back to the examiner. This, of course, is the case here, where many have not only written a funny answer but have also used their artistic skills in order to present their exam paper beautifully.
