* So You Think You Can Dance (8/7c Fox)
It all started on Sept. 9 with the first round of auditions, but we've finally arrived on the magical night of the Season 6 finale. Six dancers have made it this far, but only one of them can be crowned America's favorite dancer. In addition to tonight's dramatic ending, the evening also features performances by Adam Lambert, hip-hop dance group the Groovaloos and Leona Lewis, who debuts "I See You," the theme from James Cameron's sci-fi epic Avatar.
* CSI: NY (10/9c CBS)
Christmas in New York can be murder. The CSIs investigate the death of a reformed drug addict who had everything to live for and the evidence suggests that he was murdered. Train front man Pat Monahan guest stars in his TV acting debut as a recovered addict and musician, and Train performs. Also appearing are Kim Kardashian and LaLa Vazquez.
* Christmas with the Mormon Tabernacle Choir (8/7c PBS)
Tony Award winner Brian Stokes Mitchell (Kiss Me, Kate) joins the Mormon Tabernacle Choir and Orchestra at Temple Square for a holiday celebration that includes such seasonal classics as "Angels From the Realms of Glory," "Hallelujah" (from Handel's "Messiah"), "I Saw Three Ships," "Once in Royal David's City," "Sleigh Ride" and a medley of "The Christmas Song" and "A Crazy Christmas List." Also on hand is actor Edward Herrmann, who reads The Christmas Story.
Tonight's plastic-surgery case involves removing excess fat from a death-row inmate (Eric Stonestreet) - so he can be executed. What are the medical ethics on that? But there are also Matt developments (he was last seen strangling that prison bully), and big Christian-Kimber news. Then there's Christian's loan forgery from last week. Talk about ethics! (And friendship!) The episode is the season finale, but the premiere for "next" season (it's the final one) is in only three weeks.
The Season 6 chef showdown is over, but it's time to stir the pot and fan the flames once more for a dishy reunion special hosted by Andy Cohen. Winner Michael Voltaggio and the rest of the cheftestants are on hand to give us the scoop on kitchen calamities, tell us what unsavory items were left on the chopping block and respond to viewer questions. Series regulars and taste testers Padma Lakshmi, Tom Colicchio, Gail Simmons and Toby Young are also around to spice up the bill of fare. And the announcement of the Fan Favorite is certain to make for a flavorsome affair.
