Happy Australia Day! Ellen is reaching out to the countries of the world, and in honor of Australia Day, she's got a special Australian version of Blindfolded Musical Chairs -- with The Thunder from Down Under! These men certainly have their talents, but so does Ellen's audience. She's never been more proud than when she shows off her Hidden Audience Talents. (At least we think that's pride.) Then, VALERIE BERTINELLI has been a Hollywood star for years, but like everyone else, she struggled with her weight. Now she's discovered great ways to stay in shape, and will share them with you! Also, he's Ellen's next-door neighbor on the WB lot -- ZACHARY LEVI will stop by to tell Ellen about the new season of his hit show, "Chuck," in which he plays an average guy turned super spy. Just like Ellen.
