The Squirrel Hunters

Squirrel high up on a leafy tree
two dogs below below heard the squirrel call
And they circled the tree clockwise
To scare the squirrel and make it fall

But the squirrel circled clockwise too
Keeping the tree always between the dogs and he
So the dogs never saw the squirrel at all
And they finally stopped barking at what they couldn't see.
