Perhaps they do have a sense of humour
One evening, in a town far, far, away (OK, Canterbury) after consuming a considerable quantity of cheap studenty beer, myself and friend were walking (staggering) back to college when we came across a corner shop with one of those tin signs advertising Walls Ice Cream outside - the kind like a free-standing sandwich board on the pavement. Always being on the lookout for such things to decorate our college kitchen, we picked it up between us and set off on our way. We'd only gone a few hundred yards when a cop car screeches to a halt and the copper winds his window down and leans out. "Do you want to put that back or spend the night in cells?" he enquires. My friend looks straight at the copper and says "Ooh, that's too difficult. Ask me one on politics instead." I can smell the police station cells at this stage. But the copper just sighed and said "Put it back." So we did.
