Due to Kelly and Kelli drawing attention to the overrated, egotistical Sarah, every Monday day, before the duo can even begin their performance, they are stomped on and all attention goes to Sarah, brushing her hair for the entire assembly, leaving Oliver and Olivia, feeling sad and rejected, and disallowing them from doing their musical number. On Mondays where Luc and Theo mess with Principal Applecrab's notes, they usually switch the PSA to something so absurd, that it throws Sarah, Kelly, and Kelli off guard, and gives Luc and Theo's event full attention. However, this does not let Oliver and Olivia perform, as they are still disappointingly shooed offstage, to make room for Luc and Theo's unwarranted nonsense.
In "The Replacements", Luc and Theo pitied the duo and finally gave them the shining change to do their rap number. So, they sabotaged Sarah's twins, keeping her from drawing attention to herself, and allowed Oliver and Olivia do what they were supposed to be. After they did their performance, Luc and Theo were shocked by it's content, and began to consider which was worse. Sarah then caught everyone's attention afterwards, by chewing gum, which wasn't hurtful to Oliver and Olivia, since they performed already, but it made Luc and Theo decide that admiring Sarah was way better than Oliver and Olivia's stupid performance, and that they'd prefer that any Mondayday. This would be the only episode to feature the musical number.
