There was a king expecting a chairm from overseas, he ordered all the people to clean up their homes and environment, they all went home to do the clean up, they packed all the dirts and unusual things outside but they were not able to burn the dirts, so the chairman arrived and met all the surrounding full of dirt, so he said to the king Mr Ruler may i ask you a question, of course the king said, please how do you rule your kingdom ? The king got angry and said is it me you are calling ruler, your father is a pencil and your mother is an eraser, you yourself is a sharpener.
