S07E09 Christian Rock Hard
The guys in "Moop" find themselves at a turning point. Cartman insists on shifting the band’s style to Christian Rock, but Stan, Kyle, and Kenny aren't on board with the idea. Frustrated, Cartman decides to quit the band. Before he goes, he wagers Kyle $10 that he’ll earn a platinum album with a Christian Rock group before "Moop" can achieve the same.
