A Kangaroo Kept Getting Out Of His Enclosure.

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 got 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!”
