I don't understand why Krusty would need to move in with OFF to lose weight before the comeback show.. Yet when Bart and Lisa discover how fat he has become, they behave as if it were necessary.
I understand maybe for accountability purposes... but come on, a grown man moving (temporarily) in with another family? Especially after Homer's bad experience with Otto? I suspect maybe that the writers had more to tell us that didn't make it into the final show. Just my opinion.
