How many roofs are there in the world? The answer would obviously be quite a high number. So I pose this question. What percentage of these roofs have been built with trades-people wearing Dunlop Volleys? Answer 99 percent....And the other one percent I hear you ask, what do they wear? They don't wear nothin, cause they broke there legs when they slipped off the roof while not wearing Volleys....Fools!
