If you haven't jumped on the "Murder One" bandwagon, this may be your last chance to do so before the series' plot is too far along. After tonight, the series really gets down to business.
* "In The House" (8:30 p.m.-9 p.m., WBAL, Channel 11) -- Robin Givens, the former Mrs. Mike Tyson, guest stars as a policewoman whose car is hit by Marion (LL Cool J). Now, if Ms. Givens' ex was driving the car, that would really be an episode to watch! NBC.
* "The Babysitter's Seduction" (9 p.m.-11 p.m., WBAL, Channel 11) -- It's the same old story: Beautiful teen-age baby sitter falls in love with the man of the house, whose wife died under mysterious circumstances. Wanna bet things are not quite what they seem? Stars include Stephen Collins, Phylicia Rashad ("Cosby") and Linda Kelsey (Billie Newman on "Lou Grant"). NBC.
* "The American Experience" (9 p.m.-11 p.m., MPT, Channels 22 and 67) -- "Daley, the Last Boss" looks at the ham-fisted politician who ruled Chicago with a death grip that only became apparent to much of the country during the 1968 Democratic convention, when his determination to stop protesters outside the convention led to riots and probably cost Hubert Humphrey the presidency. PBS.
* "Murder One" (10 p.m.-11 p.m., WMAR, Channel 2) -- After two weeks of jury selection, the trial finally begins, so there should be plenty of time to recap much of what's come before. ABC.
* "Ironside" (1:05 p.m.-3:05 p.m.) and "The Return of Ironside" (3:05 a.m.-5:05 a.m. Tuesday, TBS) -- Raymond Burr had another series, remember, the one where he played a former San Francisco chief of detectives felled by a sniper's bullet and forced to use a wheelchair? Here's your chance to see the movie that spawned the series, then the reunion that aired just a year before Burr died. Of course, he was much better as Perry Mason, and some of the early "Ironsides" try so hard to be hip they're painful, but the series had its moments.
* "The Super Bowl at 30: Big Game in America" (8 p.m.-9 p.m., repeats 10 p.m.-11 p.m. and 11 p.m.-midnight, TNT) -- An examination of the big game, both as sporting event and cultural phenomenon, should get you ready for the real thing Sunday. In fact, this should do more to get you ready than all the rest of the game-week hype put together.
* "I Love Lucy" (9 p.m.-9:30 p.m., Nickelodeon) -- This premiere episode of the most influential television show ever, from 1951, has Lucy convinced Ricky's trying to kill her. After Ricky pours her a sedative she's convinced is poison, Lucy decides to go down to the Tropicana to confront him. While watching this, remember from small acorns do mighty oaks grow.
