No Fun is a song performed by Sex Bob-omb in the movie. This time, Scott isn't playing bass! Young Neil is! The song is performed when Scott enters the Chaos Theatre's underground area and he walks up to Sex Bob-omb and Neil and the song is interrupted. As Scott dies and has to restart the entire level all over again, the song is heard and interrupted again so Scott can apologize to Stephen, Neil and Kim (the apology for Kim is worth 350 points).
