Parachuting
Gertrude was about to make her first parachute jump. The instructor said, “First, you pull the big cord. If it doesn’t work, you pull the little cord. There will be a red pickup truck waiting for you when you land.”
Gertrude jumped. When she pulled the big cord, nothing happened, so she pulled the little cord. Still nothing happened. “That’s great,” she muttered. “Now I suppose the red pickup truck won’t be there either.”
