 The episode was received very well by critics and audiences alike . Many described initial misgivings that the musical concept would make the episode seem gimmicky , but these fears were , for the most part , put to rest by the fact that the episode was " logically insane " ; the singing came about organically ( through the brain aneurysm ) , and , despite the singing , the episode fit into the Scrubs continuity . Many noted that the songs fit the characters ( like Dr. Cox 's " Rant Song " ) , and that story arcs actually advanced in the episode ( Carla returning to the hospital , and J.D. and Elliot no longer living together ) .
