A lazy Thursday at the zoo found the zebras grazing on zinnias, posing for pictures, and teasing the zookeepers, whose nose was bronzed by the sun. The biggest zebra’s name was Zachary, but his friends called him Zack. Zack was a confusing zebra whose zeal for reason caused his cousins, who were naturally unreasoning, to pause in their conversasions. While they browsed, he philosophized. As they grazed, he praticed zen. Because they were Zack’s cousins, the zebras said nothing, but they wished he would muzzle himself at times.
