As he walks down the street carrying his bronze rat, he notices that a few real rats have crawled out of the alleys and sewers and begun following him down the street.
This is disconcerting, and he begins walking faster. But within a couple of blocks, the herd of rats behind him has grown to hundreds, and they begin squealing.
He begins to trot towards the Bay, looking around to see that the rats, now numbering in the MILLIONS, are still squealing and coming toward him faster and faster.
Concerned, even scared, he runs to the edge of the Bay, and throws the bronze rat as far out into the water as he can. Amazingly, the millions of rats all jump into the Bay after it and are all drowned.
The man walks back to the curio shop.
"Ah ha," says the owner, "you have come back for the story?"
