A adventurer was out in the jungle

An adventurer was out in the jungle when he came upon Tarzan.

He was painting white stripes on black zebras and black stripes on white zebras.

Although curious, the explorer returned home.

A year later he came back.

Again he finds Tarzan in the jungle.

He’s painting white stripes on black zebras and black stripes on white zebras.

Every year the explorer returns and every year it is the same scene.

Finally, he grabs Tarzan and says:

“every time I come here you are painting white stripes on black zebras, black stripes on white zebras…What does it mean???”

“Well,” he said, “Tarzan stripes forever.”
