Who is king of the forest?

Who is king of the forest?
The tiger is quite proud of his strength.One day, he is walking around in the forest.When he sees the fox, he goes up to him and asks,"Who do you think is king of the forest?" "Of course,you are," says the fox sweetly. Hearing this, the tiger is quite pleased and walks away. After a while, he meets with the monkey and he asks the same question.Certainly, the clever monkey knows how to answer such a question.
Now the tiger is more proud since others agree that he is king of the forest but he decides to ask a third animal. A moment later, he comes across the elephant, Proudly, he raises his head and asks the elephant to give him a quick answer. Angry with the tiger's way of asking the question, the elephant raises his trunk,picks the tiger up, lifts it very high in the air and then with a great roar, drops it to the ground heavily.Greatly hurt, the tiger manages to stand up and says unhappily,"Why are you so angry?If you don't know the answer,it doesn't matter." With this, the tiger walks away.
