Broadway domination is what “South Park” creators Matt Stone and Trey Parker have achieved, or course, with their smash hit “The Book of Mormon.” And with “Broadway Bro-down,” Parker and Stone have reaffirmed that they are the unlikely champions of musical theater, whether musical theater likes it or not.

“Stephen Sondheim” has hovered near the top of Google Trends all morning. And with the show name-checking more than 15 musicals (among them: “Jersey Boys,” “Sunday in the Park with George,” “Godspell,” “Spider-Man: Turn Off the Dark” and, naturally, “The Book of Mormon”), “South Park” was as much of a bawdy spoof of Broadway as it was a valentine to the American musical.

Stephen Schwartz, whose cartoon avatar can’t be featured here because of an inappropriate slogan on its shirt, once said in a concert, “You know you’ve made it when ‘South Park’ does a satire on your music.” And Elton John is no stranger to “South Park”: He appears in the episode “Chef Aid,” singing “Wake Up Wendy.”

You can watch the full episode here, but it’s extremely NSFW.
