A witch invaded a forest one day. All animals had to tell a funny joke in order not to be killed. If any animal failed to make everyone laugh, it'll be sent to death.
First, came the monkey. It told a joke, and everyone laughed, except the tortoise. So the monkey was sent to death.
It was the elephant's turn. The elephant told a very funny joke and everyone laughed. Still, the tortoise did not laugh. The witch had no choice but to kill the elephant.
It was the rabbit's turn. The rabbit nervously told a joke, but it wasn't funny and nobody laughed. This time, the tortoise laughed, and laughed, and couldn't stop laughing.
The witch, being confused, asked, "What's so funny?"
The tortoise half laughing, managing to reply, "The monkey's joke is so FUNNY!!!!!!!!!!"

-THE END-
