Musicians Kid Rock and Joe C. also guest star in the episode as themselves, performing at the annual spring break concert that Homer sneaks out to attend. Kid Rock's song "Bawitdaba" features as part of his appearance. Scully said in an interview with the "Detroit Free Press" that the staff of the show chose Kid Rock and Joe C. for the episode because the two "have a lot of stage presence" and visually are "a funny combination," and because the staff thought "they would be funny playing off Homer." According to Scully, the two musicians "had a great sense of humor [...] about themselves," with Kid Rock asking if "he could add a couple of his own lines. He wanted to introduce himself as 'the pimp of the nation.' We kept that in the show. It's quite a title." Kid Rock recorded some of his dialog over the phone, but also paid a 45-minute visit to the "Simpsons" studio in Los Angeles to record lines. Scully thought it looked like the singer enjoyed the experience and was surprised to see that he arrived on time. "My first reaction to that was, 'What kind of rock star is this?'," Scully jokingly told the "Detroit Free Press". All of Joe C.'s lines were recorded over the phone.
