DO all the pigs responsible for depositing their empty cans, plastic bottles, broken glass bottles, pizza boxes, fish and chip containers, crisp packets, cigarette packets, vomit, dog dirt and plenty of unmentionables on our streets, pavements, back alleys, gutters, paths, gardens, hedges, doorways etc. all have curly tails.

Or is it only the 'super pigs' who deposit their rubbish on the pavement within inches of rubbish bins that have them?
