So one day, all of the animals came together and made the following deal: Each will tell a joke, and if everyone doesn't laugh at it then they would kill the joke teller.
So anyway, the Rabbit went first. The Rabbit told this great joke. All of the animals were laughing hysterically, rolling on the floor and slapping their knees (if they had knees). All that is except for the Hippopotamus.
So, what could they do... the Hippo did not laugh. They had to kill the Rabbit. After promptly doing so, they gave the next turn to the lion.
The Lion told a really dumb joke, that was not funny at all. All of the animals just sat there and stared, but the Hippo started laughing a tremendous laugh. the animals asked the Hippopotamus: "why are you laughing? the Joke wasn't funny." To which the Hippo replied: "Didn't you get the Rabbit's Joke?"
What was the rabbits joke?
And if we do not all laugh, you know the consequences.
