TONIGHT'S MUST-SEES:

"Bones" and "House" season finales, 7 and 8 p.m., Fox. Last week's brilliant "House" left us in limbo. Recovering from a bus accident, Dr. House had only shards of memory. Still, he felt he'd seen signs of someone dying. By the end of the hour, he felt that Amber — his enemy, Wilson's lover — was the person. Now he tries to help. That follows a "Bones" centering on the Gormogon serial killer. If rumors — which we won't repeat — are true, this will pack a wallop.

"Dancing With the Stars," 7 p.m., ABC. Marissa Winokur's strong run is over now. She finished fourth; now the final three celebrities get their last chance. Two are prime athletes — Olympic skating champion Kristi Yamaguchi and football star Jason Taylor. They face actor Cristian de la Fuente, with a winner announced tomorrow.

OF NOTE

"The Big Bang Theory," 7 p.m., CBS. The series wraps up its first season with Leonard finally getting a chance to date Penny. He rehearses with his socially inept friends.

"How I Met Your Mother," 7:30 p.m., CBS. After a brush with death, Ted re-thinks his relationship with Stella.

"Two and a Half Men," 8 p.m., CBS. In a good episode last week, Charlie fell for Angie (Susan Blakely), who writes relationship books and is much older than he is. Now come complications: Alan likes Angie, too ... and Charlie may have dawdled with her daughter.

"The Bachelorette" season-opener, 8:02 p.m., ABC. Earlier this season, "The Bachelor" hit its low point — Brad Womack didn't pick anyone. Now one of that show's final two rejects, DeAnna Pappas, takes over.
