Dance Lessons with Dana Alexa & Matt Steffanina

YH heads to the Millennium Dance Complex in North Hollywood to catch up with YouTube choreographers Dana Alexa and Matt Steffanina to find out how they built their massive online following and what they learned about each other from their experience on "The Amazing Race"! They also talk a bit about DanceCon, why everyone should give dancing a try, and even give us a little dance tutorial!
