A gnome is in the garden busily destroying some bushes when a house cat appears.

“What are you?” asks the cat.

“A gnome,” comes the reply.

"What's a gnome?" the cat asks.

“Well," the Gnome said, "I steal food from humans. I kill their plants and I love mischief. And what, may I ask, are you?”

The cat replies, “I guess I’m a gnome.”
