A kangaroo kept getting out of his enclosure at the zoo. Knowing that he
could hop high, the zoo officials put up a ten foot fence. He was out
the next morning, just roaming around the zoo.A twenty foot fence was put up. Again he go out.
When the fence was forty feet high, a camel in the next enclosure asked the kangaroo, "How high do you think they`ll go?"
The kangaroo said, "About a thousand feet, unless somebody locks the gate at night!"
