Crocodile And The Birds

“It seems you are waiting for somebody?” asked the elephant to the crocodile.

“Yes, I am waiting for my mouth cleaners, the birds. They come, and they clean my teeth with my mouth wild opened,” said the crocodile.

“Ah, that’s good to hear. How the birds make sure that you will not shut your mouth?” asked the elephant.

“If I shut my mouth, who’ll clean my mouth next time? It’s a mutual understanding business. The birds get food from inside my teeth, and I will get my teeth cleaned free!” said the crocodile.

The elephant laughed. “You are smart!” the elephant said to the crocodile.
