Usual handbrake in png is a rock placed under tyre. Never seen anything so ridiculous asa man putting a 6 inch stone behind tyre of a 30t dumptruck.
No wait at mcmurdo antartica i saw some of the us navys finest personnell trying to start a air compressor. Being smartarse kiwis we told them to push start it. Lo and behold 3 went round the back to push and the other kept turning the key. We just looked at the sky in disbelief !
