Koko the Gorilla uses sign language to request dental work

 

Scott sez: "About a month ago, Koko, the 300-plus-pound ape who became famous for mastering more than 1,000 signs, began telling her handlers at the Gorilla Foundation in Woodside she was in pain. They quickly constructed a pain chart, offering Koko a scale from one to 10. When Koko started pointing to nine or 10, a dental appointment was made. And because anesthesia would be involved, her handlers used the opportunity to give Koko a head-to-toe exam [via Boing Boing]
