You get somebody to dress up ( could be a devil ) and go round the city playing pranks on people with poo. For example you could hang outside a public toilet and when somebody comes out follow them with a sign that says something like " Just sh*t). Or you could wait for a car to come out of a car wash and then throw a bucket of a liquidy poo like substance all over the windscreen. Or you could put loads of poo across a sidewalk so people cant past, or get Dave England to poo in different places. Or you could put poo on sidewalk buttons, or under door handles ( car doors are funny ). Or you could wear a poo suit ( like the squid suit ) and go round the town asking for hugs.
