An Old Man tried to commit suicide by carbon monoxide gas. The old man carefully hooked a long tube from the exhaust pipe of his car into the rear window of his four door sedan parked in his garage, then thoroughly sealed the back window with duct tape. Unfortunately, the car the old man used was a hydrogen fuel cell car from Honda. The Honda was so well built, and the duct tape job around the exhaust was so brilliant, and the cabin of the car was so well built, it rapidly filled with water. The old man drowned instead.
