From TV Squad: With the Academy Awards being broadcast next week, 'The Simpsons' naturally had to return to the topical satire that it's so famous for.
And this episode contained a myriad of parodies and referential humor, only some of which I recognized. Some of the scenes in the Japanese Itchy and Scratchy movie were taken from 'Kill Bill,' but Quentin Tarantino's masterpiece likely stole the scenes (also known as an homage) from other Japanese movies.
In fact, the whole episode was a nice callback to the earlier episode 'I Am Furious Yellow' from the 13th season, which introduced 'Angry Dad' as a web series. This show has been around for so long, it can't help but have continuity.
