One of the funniest moments we had at the zoo was of the gorillas in the following two photos. The younger one was sitting in the shade of a cave. When he saw the older gorilla moving towards the cave, he quickly got out of there. He knew his place! A few minutes later another gorilla tried to move in there and the older one chased him away. When he caught him he gave him a quick clip across the ear. The younger one just sat and sulked. It was so funny and so human.
