TONIGHT'S MUST-SEE

"Amne$ia" debut, 8 p.m., NBC. Many people can recite facts about rock stars and royalty and reality shows. But do they know their own lives? Could someone recognize his front-door welcome mat? Or his wife's wedding dress? Does he know the speed limit in his own neighborhood? This quiz show is built on such details. It's from "Survivor" producer Mark Burnett, who has proved (with "Are You Smarter Than a Fifth Grader?") that a quiz show can look bright and be family-friendly. As a bonus, Dennis Miller is hosts. He promises to be less acerbic than usual.

"Monk" season finale, 9 p.m., USA Network. Last week, Adrian Monk was framed for murder. The control freak was behind bars, where little can be controlled. That continues tonight, wrapping up the show's first two-parter. Monk's death has been faked, while he tries to learn who's out to get him.

OF NOTE

"When Harry Met Sally" (1989), 5 and 7 p.m., Oxygen. Rob Reiner directed Meg Ryan and Billy Crystal, in a delightful comedy about trying to navigate a platonic relationship.

"The Price is Right," 7 p.m., CBS. Here's the start of a six-week run, the first prime-time edition "Price" hosted by Drew Carey. That nudges "Ghost Whisperer" to 8; it keeps things warm until April, when CBS plans to have its post-strike hours ready.

"Bones," 7 p.m., Fox. In a rerun, Brennan's former lover visits. He promptly becomes interested in her case, involving a body in a refrigerator.

"Grey's Anatomy," 7 p.m., ABC. Here's a rerun of a relatively so-so show. George and Izzie have a tough time making their physical chemistry match their emotional link.

"Love Comes Softly" (2003), 7 p.m., Hallmark Channel. Before "Grey's Anatomy" made her famous, Katherine Heigl starred in this pleasant frontier film. She plays a young widow, befriended by a widower (Dale Midkiff). This started a series following generations of the family, with Heigl in the first two films; you can catch all seven Saturday.

"20/20," 8 p.m., ABC. An expanded edition uses a hidden camera to study people in moments of decision. It also sets up a five-part series that opens Tuesday, called "What Would You Do?"

"House," 8 p.m., Fox. This rerun starts with a woman having an apparent seizure while giving her baby a bath. Meanwhile, the staff is in flux: Wilson dines with Cuddy; Foreman is back, but shaky.

"Ghost Whisperer," 8 p.m., CBS. In a rerun, Melinda is skeptical of someone who claims to be a medium.

"Numb3rs," 9 p.m., CBS. In this rerun, a woman in witness protection is killed, and Don feels responsible.
