Paige Wiser's TV highlights

Barack Obama news conference (7 p.m., ABC, CBS, NBC, CNN, FNC): Marking the president's first 100 days in office. Just like on Election Night, CNN's John King will get to use his giant magic touch-screen.

"Lie to Me" (7 p.m., WFLD-Channel 32): Tim Roth plays a human lie detector. Fox refuses to cede this hour to the president -- it's the first time a network has refused Obama's request. You could switch back and forth and apply what you've learned.

"Lost" (8 p.m., WLS-Channel 7): Marking the series' first 100 episodes. Ben (the incomparable Michael Emerson) is warned not to kill Locke again. Because once is rude; twice is nearly unforgivable.

"Maude" (9 p.m., WMEU-Channel 48/digital channel 26.3): You've probably heard about the late Bea Arthur's famous abortion episode; see the two-parter for yourself.
