The third track of Dr Horrible's Sing-Along Blog's Commentary: The Musical, Ten-Dollar Solo. Main Part দ্বারা Stacy Shirk... and gatecrashed দ্বারা Neil Patrick Harris.
This is sort of a fan's response to Dr. Horrible. In it, the অনুরাগী dressed as "Dr. Dreadful" applies to be Dr. Horrible's sidekick. Made দ্বারা Mark Andrich.
