The track "Doubling-down" features an intense musical clash between Kyle Broflovski and Eric Cartman, who are engaged in a rap battle in the hallway over a girl named Heidi, much to the audience's amusement. As Cartman hurls insults at Kyle, Kyle attempts to defend himself and clarify that he hasn't taken Heidi, Cartman's girlfriend whom he often mistreats. However, Cartman refuses to listen, leaving Kyle with no option but to respond with sharp retorts. In the final 25 seconds of the song, both characters pour their energy into their rap skills, striving to outdo one another. Ultimately, Kyle emerges as the musical champion, and just as he seems ready to throw a punch at Cartman, the moment is cleverly obscured before it can be seen.
