The prawn cocktail was famously invented by TV Chef and harridan Fanny Craddock.
She was an awful woman, I saw her when she famously shat all over her career by abusing an amateur chef on a TV show.
At one point she pulled an awful face and my mother pointed out that she had a face like a chicken's backside and she did.
Which brings us to the joke What's the difference between a cross-country run and Fanny Craddock?
One is a pant in the country.
