After tumbling during their paso doble, Ralph Macchio and Karina Smirnoff staged an impressive comeback last week on Dancing with the Stars, nabbing their first 10 to top the leader board. "That felt so great!" Smirnoff tells TVGuide.com. "When I fell and Ralph was there for me 100 percent, that made us stronger as a couple. I knew I could rely on him 150 percent and he was there for me. That made us realize I'm only as strong as he is and he's only as strong as I am. It made us better together as a team and I think we're better than ever." The two hope to keep their momentum going this week with their "insanely cool" Viennese waltz and their cha-cha, which will be the Instant Dance. See what they have up their sleeves and why they want to get Len new scoring paddles.
