This is really good rendering of the "will Marge leave?" plot that the show does throughout the years. It combines a lot of laughs with a believable set-up. And I really enjoy the bowling themed flight of fancy Marge has.
But I don't think it is possible to define brunch better than "It's not quite breakfast, it's not quite lunch, but it comes with a slice of cantaloupe at the end. You don't get completely what you would at breakfast, but you get a good meal." That line has remained memorable throughout the years.
