Here's my second addition to San Frantastico,
Erythrocebus Patas, the Mad Monkey Musician is a Patas Monkey at the San Francisco Zoo. This is a photo of him during some down time from his day job at the zoo. He often gets tired of acting like an animal at the zoo and so, he escapes to Stern Grove to play his violin and listen to some classical music.
