Oscar was an unlucky sap. Having just spent megabucks on a skydiving 
class, he dove out of the airplane and pulled the ripcord. The chute 
emerged, tangled, and he cut it free. He then pulled the cord on the 
reserve chute, and it also was tangled. He prayed to his God and looked 
down to the ground below. To his amazement, a woman was coming up with 
equal velocity. "Hey, you know anything about parachutes?" he shouted
to her, as they passed by. The reply: "No... you know anything about 
Coleman stoves?"
