well i herd about this on the radio, a guy walks into a cage full of monkeys (im not sure the breed) and he gives one of the monkeys a present. but the other monkeys got jealous and started attacking him, they bit off him fingers and him face and another guy had too shoot them with his side arm. it was pretty messed up.

I heard the same story, they were "Mature" chimps. I have heard, over the years, that "young" chimps were playful, but "Mature" chimps were crule and mean!
