The beardless sly man Aldar-Kose lived in one aul. His eyes were sharp, his legs were quick, his hands were agile, and his mind was even more agile. Aldar-Kose loved to joke and laugh, especially at fools and misers. He had no wealth, but by cunning he did not get himself a meal of fat ram.

Zhatyr-bai was a greedy and stupid person. His flocks were large: he would start counting at dawn, and finish at dusk. Once Aldar-Kose came to him and said:

- Honorable buy, I have two rubles, but no wallet. I walk, hold the money in my hand - my hand is tired. I want to get rid of this money. Will you help me?

- Come on, come on, I will help! - buy was delighted. - Just tell me how?

“Sell me some poor little goat for two rubles,” says Aldar-Kose.

Thought, thought buy: "Well, you can sell." He caught a lame goat in the herd, skinny, barely alive, which had only two days left to die, and gave to Aldar-Kose:

- Here, take it, although it's a pity to give it away cheaply. Good kid. Give me two rubles!

Aldar-Kose took a goat, and keeps money in his fist:

- You know what, honorable buy. I changed my mind. Take two rubles and a kid to boot, and give me a lamb.

“Well, not a bad exchange,” thought Bay, “two rubles and even a kid to boot!” - and went to catch the lamb. Caught the smallest and serves Aldar-Kose:

- Here, take it. Nice lamb. Give me two rubles and a kid.

Aldar-Kose took the lamb, but he holds the money in his fist and does not let go of the goat:

- You know what, honorable buy. I changed my mind. Take two rubles, a kid and a lamb to boot, and give me a goat.

"Not a bad exchange," thought Bay, "two rubles and a goat, and even a lamb to boot." And he went to catch a goat. He caught the thinnest one and serves to Aldar-Kose:

- Here, take it, good goat. Give me two rubles, a kid and a lamb.

- Wait, wait, respectable bay! - says Aldar-Kose. - I changed my mind. Take two rubles, a kid, a lamb and a goat in addition, and give me only one ram, but let me choose it myself.

“This exchange is more profitable than all the others! - thought the delighted buy. - Two rubles, a kid, a lamb and even a goat to boot - and all this for one ram! And he says to Aldar-Kose:

- Well, choose!

He chose Aldar-Kose for himself the biggest, fatty ram, gave the bai two rubles, a kid, a lamb and a goat in addition, put the ram on his shoulders and went, and bai Zhatyr-bai laughed, rubbing his hands:

- What a fool Aldar-Kose! He gave so much good for just one ram!

Bay did not understand which of them was the fool.
