Bart's Little Fantasy

Bart's Little Fantasy is the thirty-seventh Simpsons short. It aired on the Tracey Ullman Show on February 5, 1989.

Plot
Bart, Lisa and Maggie are forced to clean up a mess they made because Marge states that she and Homer are the parents and Bart and Lisa are the children. Bart then decides to slack off by telling Lisa and Maggie a story of a world where the children are the parents and the parents are the children (The story is similar to what happens in the beginning, except the roles have been switched and Marge says "Forget it" when Homer was going to tell her a story). Bart is caught red handed by an infuriated Homer and Marge and is forced to mow the lawn if he doesn't want to help his sister. Lisa then says that they lived happily ever after in the story.
