More fun with maths:

In popular automotive television show Top Gear the presenters suggested that road works take longer than necessary because of the malign influence of that popular scapegoat 'health and safety': to demonstrate this they resurfaced a road in twenty four hours, rather than the week which the council would have needed. Very impressive! Except for the fact that in order to do this they needed to hire 32 employees rather than the usual 14, and they worked for the full 24 hours. Assuming that most workmen put in a five day, eight hour a day week. Therefore the 'inefficient' council could have got the job done in 560 man hours, rather than the 768 hours the Clarkson lead construction team needed.
