Declarations of affection can be sweet, stilted, awkward, unwanted...or, in Tom Cruise's case, just supremely strange. During a 2005 appearance on The Oprah Show, Cruise gushed to Winfrey about his new paramour, actress Katie Holmes. "I'm in love! I'm in love! I can't be cool. I can't be laid-back," he said. And then, in a decision that's likely to haunt him until the end of his career, he jumped onto Oprah's couch. And then onto the floor. And then back onto the couch. For a moment, it seemed as if the movie star might even jump on Winfrey herself. Viewers sneered that the Cruise's uncontrollable enthusiasm seemed like a poorly planned publicity stunt. For her part, Oprah just seemed bemused. "I don't know what happened to you, boy!" she joked. Cruise's response: "I don't either."
