“When I was serving my time as an engineer in the merchant navy we used to have to clean out what are called “sea chests”; they’re basically big filters for sea water that we would pump in to use as coolant and if the pumps were on when we were dock side we’d find all sorts of things like bottles, fish, crabs etc.

One day we opened up the chest, pulled out the filter and immediately saw this gold shiny thing which turned out to be a rolex watch. Usually we’d just dump out the filter but with the mitigating circumstances we went through it thoroughly and found a piece of a shirt with cufflink still attached and last but not least a nicely rotted finger.”
