A man is out walking on a warm day along the edge of a remote pond. He is on the bank enjoying the view when he suddenly loses his footing and falls into the pond. The water is not deep but he does have to struggle to make it safely back to shore. He climbs out, dripping wet, and notices that his wallet is not in his pocket.

As he ponders the pond, wondering whether he should jump back in and search for his wallet, lo, what wonders appear! As he is looking at the surface of the water, he sees a school of large carp chasing something around.

One carp emerges at water surface and what does he have in its mouth but the guy's wallet! Suddenly another carp appears at the surface and the first carp flips the wallet to the second carp who catches it in his mouth. Then a third fish appears and on and on it goes.

After watching amazed for several hours, he decided to report this strange behaviour to the experts, but they told him it was a well known phenomenon - it is known as carp-to-carp walleting.
