. . .Stepping out as an early Mirrorball favorite was the Karate Kid himself, Ralph Macchio. The baby-faced actor said he lost his shiny disco ball in the ’70s and is on the hunt to replace it. Turned out Daniel-san’s got some fight in him yet. After complaining that the 49-year-old’s working parts are a lot older than his face would betray, he and partner Karina “overanalysis creates paralysis” Smirnoff stepped out with a stellar fox trot that swept the legs on the rest of the competition. “Ain’t That a Kick in the Head?”? Extra points for doing all that side-by-side dancing the first week out. “Great showmanship, fantastic routine, plenty of content,” said Bruno, though he warned Macchio to fix the weird, creepy hand that popped out in the routine and to point his feet when he kicked. “Wow, Ralph, that was an amazing surprise,” said Carrie Ann. “That was truly gorgeous. You have such elegance in your hold.” “Best fox trot tonight, well done,” proclaimed Len. They received a total of 24, which sent Karina into hysterics. This guy’s got the whole package: He’s the star of a beloved classic film with imminently quotable lines, still got that baby face, works hard and has got that baby face. Wax on!. . .
