The first-ever “Trio Round” on tonight’s Dancing with the Stars proved to be far more successful than the dreaded “Dancing Duel.”  Here’s how it works: each couple picks an eliminated pro or a member of the troupe (grimace) to join them and show off the star to the best of their ability.  First up, were Donald Driver and Peta Murgatroyd accompanied by Karnia Smirnoff in a knock-out Jive.  Check out the fun below.
