An old lady noticed that she was about out of gas and pulled her car into the nearest self-service gas station. She forgot to put out the cigarette she was smoking as she began to pump her gas, so she flicked it away.

A spark landed on her hand and the gas nozzle. The old lady's arm caught fire. In a feverish attempt to put out the fire, she waved her arm up and down.

A Police officer was nearby, saw what was happening and fired 3 shots at the woman killing her instantly.
Shocked onlookers asked the officer why he shot her. The officer said, "She was waving a firearm."
