When I was a kid, we'd play this game called Post Office or Operator. One kid would make up something, whisper it into the ear of the next kid, who did the same, and so on till it got to the last kid. He'd say what it was, and hilarity ensued on seeing how different it was. This is what happened here.
The wife couldn't possibly have secured all that stuff all by herself. It was her perception that she was doing yeoman's work, far beyond the call and duty of a hausfrau. She complained about the episode to her friends with this perspective, and a bouncy is born. Nothing to do with Christianity, pretty lame to bring that obvious Joe Webster reference into it.
