Day said that the “Always Sunny” creators were tentative to reach out to Boggs because they were unsure if he would like the episode’s premise and, if he didn't, they would have to scrap it entirely. Fortunately, Boggs liked the idea, as Day added, “He was like, ‘I'll do it.’” Boggs makes a cameo in the memorable episode as a hallucination to help Charlie win the competition.
