Katy Perry features in the episode, probably because she was banned from being in Sesame Street for wearing a dress reaveling too much cleavege.
In the Simpsons, however, she wears a red dress with some of the simpsons's family on it.
The book Homer wants Maggie to read is called 'A fluppet's christmas carol', a parody of the muppets christmas carol possibly linking to the fact Katy Perry was banned from the muppet's rival show, Sesame Street.
