David Letterman's dalliance. Whether you think he's an average erring human or a power-wielding lech, Letterman's dignified delivery of the news that he was being blackmailed for an affair he had with an employee created a welcome new standard for coping with such things. Tiger Woods needs to watch more TV. 'Glee.' After a mind-blowing early premiere, the Fox show achieved the impossible. With relatively few missteps, creator Ryan Murphy and his writers and cast gave us a solid season of genre-bending television and a whole new reason to love both Journey and Beyonce. President Barack Obama goes late night. The first president since Ronald Reagan to understand the power and intimacy of the genre, Obama uses television, and the Internet, in ways that will redefine the democratic process. 'Dexter.'

Like parenting is hard enough without trash-talking your spouse and free plastic surgery always comes with a price. Oh, and don't put your family on television. 'Big Love.' The HBO drama continues to be one of the best written and best acted shows on television and one of these days the Academy of Television Arts and Sciences will come to its senses and recognize that. The seduction of America by Don Draper. 'Mad Men's' heartthrob is not a nice guy. He cheats on his wife, his mistress, his boss, his brother and the American public (he's an ad man for heaven's sake). But we love him, which is troubling. LeBron James' last-minute 3-pointer. At the end of the second game in their NBA play-off series, with one second left on the clock, James swished it from the top of the key. The Cleveland Cavaliers beat Orlando's Magic by one point and proved once and for all that it ain't over 'til it's over. Mackenzie Phillips on Oprah. A former TV star confesses that she had a sexual affair with her former pop music star father. A few months later, the talk show star who facilitated the confession announces she's ending her show. Coincidence? Or just the recognition that there's really no place to go from here.
