"Why are you crying crocodile?" Asked an animal of the savanna.
"Because I killed and ate my best friend, the antelope" Said the crocodile.
"And why did you do that if you knew you'd feel bad and regret doing it?"
"But I'm not crying because of that..."
"Then why?"
"I'm crying because if I had known that my dear friend, the antelope, was so delicious sooner, I wouldn't have waited so long to kill him and eat him."
The end.
