Closing the Gate
One morning a zookeeper discovered that a kangaroo was out of his enclosure and roaming freely in the zoo. Knowing the kangaroos can hop very high, he instructed the zoo workers to construct a ten foot high fence around the kangaroo’s enclosure.
The next morning the zookeeper discovered that the kangaroo had once again gotten out of his enclosure, so this time he instructed the zoo workers to construct a twenty foot high fence. The next morning the kangaroo was once again found wandering around the zoo. This time the fence was extended to 40 feet high.
The camel in the next enclosure asked the kangaroo, “How high do you think they will go?”
“Pretty high,” the kangaroo replied, “unless somebody figures out to close the gate at night.”
