A certain chief had a fondness for listening to stories, restaurant furniture. One day, he held a grand banquet. At his repeated request, a reading table, a guest from out of town told a very interesting story: This guest had met a very arrogant person in the city. He said to him: "Please guess what I have in my pocket. If you guess correctly, I will give you half of these eggs; if you can guess the number of eggs, I will give you all ten eggs." That person thought for a long time and said: "Friend, although I am not stupid, it is impossible for me to know everything. I cannot guess what is inside the circle." The guest said: "Guess again, this thing has a white outside and a yellow inside." "I guessed it!" That person shouted loudly, "It must be a pile of radishes, with a potato hidden in the middle." Upon hearing this, the guests all laughed, and the chief laughed even harder. Finally, he asked: "That's truly a fool, but respected friend, now please tell us, what did you actually have in your pocket?"
