This isn't a bumper sticker (not thread creep again, Roger?)but 'Spaw at least might appreciate it. On the way in to work half an hour ago I followed what I call a "sludge gulper" or "honey wagon" that had just emptied the portaloos from a building site.
The registration plate included the letters LOO, the firm's name was Chamberpots and its slogan was "Number One in the Number Twos business"!
