Two salesmen were going door to door. They knocked on one door and a woman answered. She was extremely unhappy to see them.
She told them angrily she did not want to hear their offer and slammed the door in their faces. But to her surprise, the door bounced back open. She tried again and really slammed the door hard, but again it was the same result – the door bounced back open.
Convinced the rude salesmen were sticking a foot in her door, she reared back to give it a huge slam that would teach them a lesson, when one of the men said, “Ma’am, before you do that again, you need to move your cat.”
