At first glimpse you might believe this Mandrill is making a MONKEY out of you.
Because the straight-faced Mandrill doesnt look too happy to see visitors at the San Francisco Zoo, USA, as he gives them the MIDDLE FINGER.
But infact this unfortunate monkey named Jackson suffers from a bad case of arthritis and is unable to lower his middle finger! A Zoo keeper said I have visitors approach me all the time to tell me about Jacksons antics Mark Rogers the photographer goes to visit him once a month and said Hes a bit grumpy and really doesnt like being photographed im pretty sure he uses it to his advantage! - SEE CATERS COPY *** Local Caption ***
