    10. BOLIVIAN MONKEYS

    To beat the bright summer sun and have a bit of fun, the Bolivian monkeys at the London Zoo started swiping sunglasses off visitors’ heads. The animals amassed an impressive collection of shades, trying out all types of styles. In an effort to stop the swiping, the zoo covered the monkeys' stolen sunglasses with a bad-tasting and non-toxic bitter apple spray. (Digital Journal)
