A boy scout troop went on a hike. Crossing over a stream, one of
the boys dropped his wallet into the water. Suddenly a carp jumped, grabbed
the wallet and tossed it to another carp. Then that carp passed it to
another carp, and all over the river carp appeared and tossed the wallet back
"Well, boys," said the Scout leader, "you've just seen a rare case
of carp-to-carp walleting."
