I've heard the phrase 'shit a brick', but I never realized it was a gold brick.
A town in Japan has come up with a novel way of beating the country's crippling recession: by extracting gold from its sewage.
The appropriately named town of Suwa in the Nagano Prefecture is collecting the precious metal from the waste it processes, earning the sewerage plant hundreds of thousands of dollars.
Sewerage plant official Yoshihide Nakayama is in charge of reclaiming the gold.
"When we found the gold in the sewage we immediately put it under lock and key," he said.
Mr Nakayama's line of work is not for those with a weak stomach or a delicate constitution.
