 Recurring guest voice actors Alexandra Breckenridge, actor Ralph Garman and writer Danny Smith also made minor appearances.Along with the episode's title, the Meg and Joe plot line heavily borrows from the storyline, as well as several scenes, of "The Hand That Rocks the Cradle".The scene where Evil Stewie appears in the empty machine is a direct homage to the "Star Trek" episode "The Enemy Within," down to the lighting and piano fill, which has a similar premise involving an evil duplicate of Captain Kirk.
