"You're not making Christianity better, you're just making rock n roll worse" is one of the many memorable lines from King of the Hill, the best animated prime time show on network TV in my expert opinion. I saw this tag (???) on Saturday before Easter Sunday.
Later in the same episode, Bobby is wearing a shirt that reads "Satan Sucks." And the confusion around the moral paradox that follows is hilarious:
HANK: Bobby, take that off! You can not wear a t-shirt with that word on it.
BILL: Such vulgarity! Wait, which word, Hank, "Satan" or "sucks?"
HANK: Well, either one.
BOBBY: Why not, Dad? Satan does suck.
HANK: I know, but --
DALE: He's right, Hank. What does your t-shirt say? "Satan Rules?"
