Good-bye "Conan O'Brien."

February 20, 2009 9:01:56 AM PST
This is it for Conan O'Brien. Tonight is his final show as host of "Late Night with Conan O'Brien" on NBC before he takes over the "Tonight" show later in the year. The White Stripes will perform. But, beyond that, O'Brien isn't saying who else will stop by this evening. A black hole? Is that where money entrusted to Bernie Madoff wound up? ABC's "20/20" asks the questions: How did Madoff fool his investors? Where did all that money go? "Wife Swap" and "Supernanny" are earlier on ABC.

"Dateline: NBC" looks at the death of a woman who died in the office of a church. "Howie Do It" is earlier on NBC. And, on "Friday Night Lights," the other players give the new quarterback a rite of initiation.

The season finales of both "Monk" and "Pysch" are on USA. After "Terminator: The Sarah Connor Chronicles," the "Dollhouse" heroine could be in trouble on tonight's episode on Fox.

CBS is in reruns tonight: "Ghost Whisperer," "Flashpoint" and "Numbers."

And, "Friday Night Smackdown!" is on MyNetworkTV.
