Two church members were going door-to-door and knocked on Vickie's door. She was not happy to see them and told them in no uncertain terms that she did not want to hear their message and slammed the door in their faces. 

To Vickie's surprise, however, the door did not close and in fact, bounced back open. 

She tried again and really put her back into it, and slammed the door again with all her might, but got the same result. The door bounced back open. 

Convinced these rude young people were sticking their foot in the door, she reared back to give it a slam that would teach them a lesson, when one of them said, "Ma'am, before you do that again, you need to move your cat."
