Wide-angle video shot. A woman wearing sunglasses and a bright blazer performs the classic "Gangnam Style" horse-riding dance in front of the glass, squatting with legs apart, wrists crossed, bouncing to the rhythm. The silverback gorilla seems to hear the call; it squats (its natural posture) and bounces up and down excitedly, waving its crossed hands in front of its chest. Its moves look even more standard and powerful than the human's, full of addictive comedy.
