 On the other hand , others thought the music felt forced . Inevitably , almost all reviews , both positive and negative , compared the episode to Buffy the Vampire Slayer 's musical episode , " Once More , with Feeling " . This comparison was also made by Bill Lawrence , who credits Buffy for inspiring Scrubs ' propensity for " big " episodes ( such as this one , the multi @-@ camera " My Life in Four Cameras " , and the Wizard of Oz parody " My Way Home " ) . The singing abilities of the cast ( Chalke in particular ) came under some fire , but most critics agreed that most were competent , and that anything beyond that simply did not matter . Reyes and Faison were the only members of the cast ( besides the Broadway star D 'Abruzzo ) to receive praise for their singing abilities . In general , the final assessments were positive . The episode was called " the show 's best episode thus far this season " , " worth all the hype " , and " a heck of a lot of fun " . The episode is also the most popular download of the entire series of Scrubs in the iTunes Store .
