Several years ago,
jarkman and I recorded the noise made by a sack of hammers, so that there would be a reference should anyone go 'Bloody hell that thing sounds like a sack of hammers...'
It was not as exciting a noise as one had been led to believe, though I still have hope that the reference sack of spanners will prove more interesting.
This weekend, we discover that Pitch isn't all that black.
I suspect that there are many more poor similies out there to be discovered.
