Jemaine or Bret break into song in each episode. The songs are built into the narrative structure of the show in several different ways. Some songs form part of the plot of the show. In these instances, Bret or Jemaine sing to another character. Other songs serve as the internal monologue of one of the two. Typically, at least once per show, a song is shot in the form of a music video. Some songs use a combination of the styles. For example, in the first episode, "Sally", the song "Most Beautiful Girl in the Room" is a mix of Jemaine's thoughts and his spoken invitations to Sally to get a kebab and to go back to his place. The music video for "Business Time" (from "Sally Returns") depicts a daydream that Jemaine is having. As the series evolved, other main characters also had their own musical interludes, depicted in a similar manner to Jemaine and Bret's own songs.
