Publicist Jessie (Jill Ritchie) negatively refers to George Michael (Michael Cera) as "Opie", a reference to a character on The Andy Griffith Show (1960) prompting the narrator to say "Jessie had gone too far, and had best watch her mouth." The uncredited narrator is executive producer Ron Howard, who, as a young boy, played Opie on The Andy Griffith Show (1960).
When we see the newspaper headline with the news of Lindsay (Portia de Rossi) and Lucille (Jessica Walter)'s altercation at Klimpy's, another story is titled "Musician Sues Restaurant Over Use Of Name". This is a reference to the band Arrested Development suing the show's producers over the show's name.
When Gob (Will Arnett) is performing his Aztec Tomb illusion, the music that can be heard is the opening to The Beatles song "The Continuing Story of Bungalow Bill."
