For many years I had a lot of association with fairly senior Japanese businessmen, and from time to time took them into the bush for some local sightseeing. On one occasion, one of them looked on the ground, pointed to some objects, and asked: "Is that the shit of the kangaroo?"
On being assured that it was, indeed, the shit of the kangaroo, the group proceeded to collect the little black marble-sized objects, wrap them in tissues and put them in their pockets to take home.
I guess they are now mounted on some corporate desk in Tokyo....if they didn't mistake them for sweets on the flight home.
