"How the Cookie Crumbles" the episode where Muffy has to make up a recipe for the Strawberry festival, and her friends mess around with a cookie recipe. Binky adds bananas... after Baily accidentally bakes them, she enters them in the contest and wins... she then sells them, taking ALL the credit, to the annoyance of her friends. Binky says "I said Banana! Banana was my idea! Without me, there is NO banana!" twice in the episode. Hope that helps.
