Beautiful silverback. At our zoo, the silverback is a total ham, and does not have the same dignity as your guy. He loves to shock the public - I've seen him do it (by it, I mean a foul activity - not self love, this guys act took a lot of forethought and he repeats it nearly every time I go) many times. The public usually reacts the way he wants, with disgust, and he gets a big smile and chuckles to himself. Needless to say, he's got the audiences number - it always cracks me up!
