Karina was a topic of discussion on The Tonight Show with Jay Leno on Thursday night. Ralph Macchio was Jay's guest talking about his current run on Dancing with the Stars. Jay tried to make Ralph blush by showing him Karina's Playboy Magazine cover, but Ralph was the perfect partner and gentleman. "I am the envy of millions," he said. Wanda Sykes' comment "Let me see that thing!" made the audience roar with laughter. Watch the video clip here.
