Just the other week, a member of the public was filling up his Datsun with petrol. But that day, there was a fault with the autoshut off mechanism at the bowser. Once his tank was full, fuel sprayed from the filler neck and burped all over his arm.
Frustrated at this he stormed into the shop paid for his fuel and drove off in a huff. So frustrated was he, he just had to have a smoke. He wound down his window, pulled out a cigarette, and lit it. Next thing you know his whole arm is on fire. Not wanting to burn the interior of his beloved Datsun, he flung his arm out the window, waving it about to extinguish the flame.
Then, what would you know, flashing lights and a siren. This fellow get pulled over by the fuzz and gets charged with possession of a fire arm.
