Crane and Wolf

Once a hungry wolf was devouring his prey. In a bid to finish it quickly he swallowed a big bite of the flesh but a bone also went in and got stuck in his throat. It hurt him very much. So he decided to go to a crane to help him. 

Crane and wolf

He said, “Well dear friend, I am in great trouble. Please pick out the bone in my throat.” The crane was afraid lest the wolf should bite off his head. But the wolf assured him of safety and a big reward besides, for the service. At last the crane agreed to do the needful. It put its long beak into the throat of the wolf and pulled out the bone. The wolf was very happy now. The crane demanded the promised reward for his service. 
The wolf, at once, said, “Isn’t it a big reward that 1 have not bitten off your head when it could not have escaped my teeth.” The crane hopped away disappointedly.
