A man (was leaving) his house when he (saw) some workmen who (were putting) rubbish in the road outside his front door. He (told) them to stop but they (refused) and (showed) him a piece of paper explaining that his street (was) now a rubbish dump. The man (went) red with anger and (ran) to speak to a policeman who (was walking) up the street. The policeman (did) nothing to stop the workmen, and the man (was) about to cry when he (realized) that the 'policeman' was actually a television presenter, and they (were filming) him for a television programme where the presenter plays practical jokes on people.
