Someone mixed “Hello!” from The Book Of Mormon into South Park

Even before penning the Tony-winning The Book Of Mormon, South Park creators Trey Parker and Matt Stone never bothered to hide the influence of musical theater on their work. The residents of their famously excitable Colorado town have always burst into elaborately choreographed song at the drop of a hat (especially in Bigger, Longer, And Uncut, the South Park feature film, which is a musical in all but name). But though Parker and Stone gave their stage work a wink in the ending to Season 15’s musical-themed episode “Broadway Bro Down,” they've never incorporated any of their Book Of Mormon work directly into the show.
