Is "South Park" the most moral show on TV?

In this case, a brilliant parody of not only the Jonas Brothers but the entire Disney company ethos attacks the absurdity of using a hot boy band wearing “purity rings” to sell sex to young girls. (To be honest, not having daughters, I’m not immersed enough in the Jonascult to know if I agree with the specific charge, but they make a hell of an argument.)
