The Way This Gorilla Slides Up To The Glass Is Scary And Impressive!

So many questions about the gorilla in this short video. How many times do you think this gorilla practiced this slide? Do you think this gorilla has done this more than once? The way he slides and then turns around to show that back side is also another question we have. Did he learn that move? Is that something he and the other gorillas in the enclosure do to each other, or just to the humans that come to visit? Then there is the "LOOK" at the end which makes us think that the gorilla is more human that several friends we know!
