Any seasoned traveller soon learns to avoid anything wished on them as a ‘regional speciality’, because all the term means is that the dish is so unpleasant the people living everywhere else will bite off their own legs rather than eat it. But hosts still press it upon distant guests anyway: ‘Go on, have the dog’s head stuffed with macerated cabbage and pork noses — it’s a regional speciality.’

— The Last Continent by Terry Pratchett, Nigel Planer
