Once it was a very cold night. An Arab lay asleep inside his tent. His camel stood tied outside the tent. At midnight the camel began to shiver with cold. It put its head inside the tent and said "my master it is very cold outside the tent I am shivering all over it would be very kind of you if you let me put my head inside the tent ". The Arab allowed it to so. After sometime the camel said "May I put my neck inside as it is very cold outside ". The Arab permitted it. A little latter then came said "My dear master may I put my front two legs I am shivering all over". The Arab took pity on it. In this way the camel entered in the tent. After sometime the camel pushed his master out of the tent by saying that this tent is very small for both of us. Moral: Nip the evil in the bud.
