There was once a man who had an obsession for tractors. His walls were covered in posters of tractors, his mantelpiece covered in tractor plates. Tractors tractors tractors all over his house. His wife, naturally, because she was sane, hated it. So she gave him the ultimatum - the tractors or her. After much thought he decided to get rid of the tractors and promptly took all of the memorabilia to the dump. He returned home to find his house on fire and that the smoke was preventing his wife and kids from finding the door. So the man took a massive deep breath. He sucked in with all his might. The smoke sucked out of the house and his family escaped. Later on, a firefighter asked him how he did it. "That's easy," he replied. "I'm an extractor fan".
