One day an Arab and his camel were crossing the desert. Night came and the temperature became colder. The Arab put up his tent and tied the camel to it. The Arab went to sleep.
The temperature became slightly colder and the camel asked the Arab if he (camel) could just put his nose in the tent to warm up. The Arab agreed that the camel could just put his nose in, because the tent was small and there was no room for 2. So the camel's nose became warm and after a while the temperature went down even more.
The camel asked the Arab again, if he (camel) could just put his fore legs in because they were very cold. The Arab reluctantly agreed that the camel could only put his fore legs in and no more. So the camel moved in his fore legs and they became warm. After sometime the camel asked the Arab again that he had to put in his hind legs or else he won't be able to make the journey the next morning with frozen legs. So the Arab agreed and once the camel moved his hind legs in, there was no more room in the tent for the Arab and the Arab was kicked out.
