Two young missionaries were going door to door. They knocked on the door of one woman who was not at all happy to see them. The woman told them in no uncertain terms that she did not want to hear their message and slammed the door in their faces. To her surprise, however, the door did not close and, in fact, almost magically bounced back open.

She tried again, really putting her back into it and slammed the door again with the same amazing result - the door bounced back again.

Convinced that one of the young religious zealots was sticking his foot in the door, she reared back to give it a third slam. She felt this would really teach them a lesson. But before she could act, one of them stopped her and politely said, "Ma'am, before you do that again, you really should move your cat."
