I know it's a zombie episode and a movie parody besides, but the thing I always go back to in these threads is Barthood.
Where finally, we have an episode where Bart points out that Lisa gets a lot of show stealing and every effort made to make things about her, often to others detriment.
The moral of the episode however, was that it's fine because Lisa is Bart's muse.
And the greatest irony of all was that this was sandwiched on either side by two Lisa episodes.
