There's really only one way to say it -- DENNIS QUAID is here! Actually, he says it better. Ellen's favorite hidden-camera prankster returns today -- and who knows what he'll get himself involved with this time?! First he'll give Ellen all the details on his movie, "Legion." Then, from the hilarious show "Modern Family," SOFIA VERGARA is stopping by. Sofia is from Columbia, so Ellen has a great idea how she can help Ellen's Quest for World Domination with a simple long-distance phone call! Then, everybody was talking about "The Bachelor" contestant MICHELLE. She'll be doing some talking of her own today when she sits down with Ellen and gives her all the behind-the-scenes details!
