Once upon a time, there was a little monkey who lived in the forest. One day, the little monkey was playing on a tree and swinging from one branch to the other. Suddenly, he felt a sharp pain in his tail. He saw that a sharp thorn had pricked his tail. It was giving him a lot of pain. The monkey could not remove the thorn himself so he decided to go to the city. On his way, he met a man who was carrying a knife. The monkey requested the man to remove the painful thorn from his tail. The man agreed but while he was removing the thorn with his knife, he accidentally cut off the monkey’s tail. The monkey was upset and annoyed. He said to the man, “You cut off my tail! Now you will have to give me your knife. I will bite you if you don’t.” The man readily agreed to give the knife to the monkey and went away. The monkey was so happy on getting the knife that he started singing, “I lost my tail but I got a knife. Dum, dum, dum.”
