Seven chimpanzees use ingenuity to escape their enclosure at the Kansas City Zoo

One of them found or broke off a 5- or 6-foot log or branch, leaned it against a wall and clambered to the top. Then that chimp persuaded six friends to join him. Visitors moved into protected areas, but zoo director Randy Wisthoff said the public was never in danger. The animals were lured back by fruits, veggies and finally malted milk balls.
