The big, ugly, hairless ape isn't going to get through life on his looks or charm. He needs valuable career skills. So the little monkey sets about preparing him to be a productive member of monkey society.
He signals the human to extend his hand, then places leaves in that hand. Next, the monkey closes the human's hand, crushing the leaves. He repeats the process until he is convinced that the human has learned it. The human is now ready to add leaf crushing to his résumé.
Neatorama readers, test your own knowledge on nearby leaves. Can you learn this skill by simply watching this video? Report on the results of your efforts in the comments.
