Riddle: A retired zookeeper owned a huge house with a very large and beautifully landscaped yard. The neighbors of the man drove past his home daily, and admired his arrangement of all the large trees and numerous healthy bushes which adorned the front yard. One day, a neighbor drove by the former zookeeper's house, and was astonished to see a living, fully-grown ostrich standing in the yard. A week later, neighbors reported seeing a live, fully-grown bear standing near the ostrich. As the next few weeks passed, the neighbors saw a tiger, a lion, a hippopotamus, and finally an elephant appear in the yard of the retired zookeeper --- all fully- grown and alive, but without any cages or bars to protect the neighborhood from them. Amazingly, not one person who lived in that area ever expressed any fear of the uncaged animals, and no one ever called the police for protection. Were these people living in the Twilight Zone? What exactly was going on here, and why weren't any of these people afraid for their lives?
Answer: The retired zookeeper was also a professional topiary expert. Mixing together the best of his two worlds, he sculpted zoo animals from his fully-grown, healthy, living bushes in his front yard, much to the delight of his neighbors.
