Skydiving
Ole was to learn skydiving. He was told that shortly after jumping out of the plane he was to pull the short rip cord and that will open a small parachute which will open the large chute and if by chance the large chute fails to open, he should pull the other cord which will open the large parachute. He was told that a car will be on the ground to take him back to the airport.
Ole jumps out of the plane and proceeds to pull the first cord. The small chute doesn't open so he pulls the last cord and the large parachute doesn't open either. Ole thinks to himself, "It will be just my luck that the car won't be there either"
