From a novelty rock emporium at Blackpool. I've said it before and I'll say it again, any object is better when it can be described as 'novelty'. This certainly fits the bill.
When I bought this, I had never heard the phrase 'giddy kipper', but I enjoyed the random nature of a kipper made out of rock. I now understand 'giddy kipper' to be a Lancastrian epithet for someone who's rather overexcited. Who wouldn't be a giddy kipper at Blackpool?
