Sheela and Jairam were a poor old couple. Their only possession was one cow. Once, Jairam fell very sick. Soon all their money was used-up in buying medicines and they realised that they would have tq sell their cow in order to bear the rest of the expenses. Sheela decided to go to the market and sell the cow. She set off, leading the cow by a rope. One the way, she met four young men. They were the local bullies who enjoyed teasing and tormenting old people. When they saw old Sheela with her cow, they decided to play a trick. On of them sneaked up behind her, untied the cow and tied a goat in its place. Sheela had been walking immersed in thought, worried about Jairam. Suddenly she heard a goat bleat behind her. She turned around and was surprised to see that her oowhad vanished. She was leading a goat to the market. The four . bullies cere up to her and said, "There is magic in the air these days. See, it turned your cow into a goat. "Poor Sheela walked on with the goat. After a little while, the boys untied the goat and tied a rooster in its place. The rooster crowed and Sheela was surprised again. The goat had turned into a rooster in its place. The rooster crowed and Sheela was surprised agam. The goat had turned into a rooster! The four bullies shouted, "Magic in the air, Grandma." She resumed walking with the rooster in tow. After a few minutes the boys crept up again, untied the rooster and tied a log of wood in its place. A few moments later Sheela realised that she was dragging a log of wood with a rope. Again, the bullies shouted, "Magic in the air, Grandma." After a few minutes, the boys untied the log of wood too and ran away with it. When Sheela finally reached the market, she found that she had nothing but a rope in her hand. She came back home dejected as she had lost the cow. She told Jairam the whole story. He immediately understood what had happened. "Make chapatti, vegetable and kheer for lunch tomorrow," he said. "Cook for atleast four people. I will come home with some guests. As soon as they come you must say, 'I cooked what the rabbit told me. Come, eat your lunch.' Leave everything else to me," Jairam reassured her. The next morning Jairam went and borrowed two identical rabbits from a friend. He left one at home, tied the other one with a string and started walking towards the market with it. On the way he too met the four bullies. 'Hey Grandfather ! 'they yelled, "your wife's cow vanished yesterday. Where are you taking this rabbit now ?" Jairam sighed sadly and said, "This rabbit is like my son. It obeys everything I say. But now I am sick and we need money, so I am going to sell it in the market." The four bullies were surprised when they heard this. "Does it really understand what you say, Grandfather ?" they asked. Jairam replied, "Of course it does. Here. watch me." Jairam turned towards the rabbit and said, "Hop home and tell Sheela to make chapattis. vegetable and kheer for four people." Then he untied the string and let the rabbit hop away. He turned towards the four boys and said, "Come home and have lunch with me.'' Then they reached his house his wife welcomed them and said. '·1 cooked what the rabbit asked me to cook. Come, eat your lunch." She served the chapattis, vegetable and kheer to all of them. The four bullies were stunned when they saw the rabbit sitting in the comer. They told Jairam, "We will buy your rabbit.'' Jairam pretended to think and said, "It is very precious to me." The four bullies immediately offered him a higher price. Jairam showed some reluctance. The moment he agreed to sell the rabbit they paid him the money and left with the rabbit immediately. The four bullies decided to test the rabbit's abilities. They had been blackmailing a landlord for money. So they told the rabbit, "Go and tell the landlord to bring us the money within ten minutes." The rabbit hopped off They waited for an hour but the landlord did not come with the money. They marched to his house and yelled, "Give us the money and our rabbit." The landlord had been waiting for a chance to teach these bullies a lesson. He ordered his strongest bodyguard to give them a good thrashing. Bleeding and bruised they went back to Jairam 's house and said, "You fooled us. Return our money at once." Jairam simply smiled and said, "The money has disappeared! There is magic in the air.'' What did the four bullies see when they reached Jairam 's house? ·
