"American Idol" (8 p.m., Fox): "American Idol" has had another competition on stage this season -- one between host Ryan Seacrest and judge Simon Cowell. Each week, the two have a verbal sparring -- whether it is over contestants or picking on how the other dresses. These two seem as if they can never get along. They are always nitpicking at each other. "It's not for the show," Seacrest said recently. "We do this kind of thing all the time to each other. That's the way we talk to each other." The two won't have too much more to argue over this season. "American Idol" names its 2006 winner tonight. It's a culmination of a season in which "Idol" experienced its biggest ratings.
"Lost" (9 p.m., ABC): Last season's "Lost" finale, which ended with Jack and Locke peering down the hatch, was a disappointment for some fans, who expected more. This season, the producers are promising a cliffhanger that will rock our world. The two-hour episode has the castaways planning to finally confront The Others and get back Walt.
