Lisa goes to the money jar. Devil-Lisa then appears telling her to get the money, but then Angel-Lisa appears telling her to remember her promise. Then Maggie appears, catching Lisa in the act and forcing her to leave. Maggie then tries to steal the money. Angel-Maggie appears shaking her head, then Devil-Maggie appears nodding. Bart catches Maggie in the act and scolds her, forcing her to leave. Taking the opportunity, Bart decides to steal the money, with both Devil-Bart and Angel-Bart agreeing. However, Bart is shocked to see that there's only one dollar bill inside the jar. Annoyed, he decides not to steal the buck, saying, "Can't even trust your own mother."
