Recurring theme Mary Murphy's loud, high pitched scream, reserved for performances she liked best, made a reappearance this season, along with the added element of the "hot tamale train", which can make the viewers have the ability to keep dancers safe from elimination. On the first performance show, Murphy enjoyed Anya Garnis and Danny Tidwell's jive performance so much, she made a metaphor of a "hot tamale train" having "just pulled up and let Anya off the train, special delivery." Two weeks later, she gave Sabra Johnson and Dominic Sandoval "two tickets on the hot tamale train" for their outstanding rumba performance. The phrase was regularly referred to by Murphy throughout the rest of the season, sometimes with an added distinction of being in "first class" for truly extraordinary routines. On the week before the final performance show, she brought the metaphor to a close by noting that the "hot tamale train was entering finale station." Controversy The sixth week of competition marked controversy surrounding Emmy-nominated choreographers Wade Robson and Mia Michaels. The controversy regarding Wade Robson was due to the anti-war solo routine he created for the top 10 contestants. His choreography was meant to be a dance promoting peace, but was considered by some viewers as a political statement against the Iraq War. The dancers wore T-shirts on which they painted words of their own choosing, such as "compassion", "understanding", "unity", and "peace." The following night, Nigel Lythgoe addressed the controversy by stating that the choreography was not in any way meant to be against the troops fighting in the war. He did not wish anyone to be offended by a routine that had words such as "peace" and "compassion" in it. To make light of the moment, Lythgoe joked that he was more upset to have seen the same routine ten times. The controversy surrounding Mia Michaels was regarding a jacket she wore during the performance show. The garment was a United States Marine Corps Blue Dress jacket with red piping, which only enlisted Marines are able to wear. In addition, a Marine Corps rank insignia was sewn upside-down and in the wrong location on the sleeve. Michaels addressed this by apologizing and stating that a friend of hers had given her the jacket, and that she wore it as a fashion statement, noting that she had no idea of its tradition or that it would offend
