A 15-year-old girl denied a horse from her parents has turned to a cow to fulfil her riding dreams. Teenager Regina Mayer, from southern Germany, is able to ride her cow, Luna. She has even trained her bovine pet to soar over a beer-crate hurdle like a regular show jumper. Why, you may well ask, when most cow-owners are surely content to let the creatures chew and lactate and sit down to indicate the imminent arrival of rain? Well, Regina's parents wouldn't let her have a horse.

For our latest mission, we put a Carnegie Hall orchestra in the middle of New York City and placed an empty podium in front of the musicians with a sign that read, “Conduct Us.” Random New Yorkers who accepted the challenge were given the opportunity to conduct this world-class orchestra.
