One of the fun things cartoons do that live action shows don’t is mess with their intros. The Simpsons are famous for constantly changing the couch gag and what Bart writes on the blackboard, while Family Guy have occasionally had characters interrupt the chorus line in theirs. But while most of the episodes on the South Park: The Complete Twenty-Third Season Blu-ray and DVD sets have very different openings as well, the changes go far beyond the start of the show.
