"Hair on a man's chest is thought to denote strength. The gorilla is the most powerful of bipeds and has hair on every place on his body except for his chest."

"Embarrassment and shyness, also considered self-aware emotions, seem to be about being seen- in a bad light, or when one does not wish to be seen. Koko, the signing gorilla, has shown a rather touching form of embarrassment. Among her toys are a number of puppets and dolls. She was once seen signing "kiss" to her alligator puppet. On another occasion Koko signed "kiss" to her blue gorilla doll and "bad bad" to her pink gorilla doll. Then she signed "chase tickle," slammed the dolls together, made them wrestle, and signed "good gorilla good good." On each occasion, and other similar occasions, the moment she saw that she was being watched, she stopped playing."
