Pat and Mick were standing looking up at a flagpole. A blonde drives up in a jeep, stops and asks the boys what they are doing. Pat says 'we're trying to measure the height of this flagpole. The blonde says'Hang on a minute, nips over to the jeep and comes back with a spanner, opens the bolts at the bottom and lays the flagpole down, takes out a tape measure measure the pole and says 18' 2". Pat thanks her and as she drives away says to Mick 'Typical bloody blonde, ask her for the height and she gives you the length!
