Once a certain donkey driver turned to Khoja Nasreddin: “Oh, wise one, explain one thing to me, otherwise I will lose my mind.”

- I was given ten donkeys to drive to another city, and I hit the road. Before the road, I counted them, there were 10. I sat on a donkey and we drove off. On the way, I decided to count the donkeys again, and, to my horror, there were nine of them. Then I decided to make a halt, dismounted, and again counted my flock, there were ten again! With relief I set off again, but when I decided to count the donkeys again, there were nine again! And so every time and all the way, there are always 9 on their way, and on a halt 10. Take a look yourself, O Nasruddin, and tell me how many donkeys you see here? - Eleven.
