This one really blew us away. On Dancing with the Stars Season 21 Episode 9: Showstoppers Night, Alexa and Mark gave an inpsiring performance with their perfect scoring Contemporary routine. Sadly, the couple was also eliminated that same night.

Is there an echo in here? Bindi and Derek danced a third perfect scoring routine on Dancing with the Stars Season 21 Episode 9: Showstoppers Night. Bindi even performed part of the routine with a blindfold.

Showstoppers night also required that the couples partner up with another team to perform a second routine.
