YouTube Description: Monkey teaches human how to crunch leaves.
Kudos to the YouTube Commenter 'Whatever' that wrote, "The monkey should teach this human how to turn his cell phone to the side..."
And to YouTube Commenter 'Joseph Larson' who wrote, "Is he teaching the human to crush leaves or using the human to crush leaves? He realizes that the bigger hand can crush bigger leaves, so he uses it."
