The two NBC sitcoms that were showcased after Sunday's Super Bowl, "The Good Life" and "The John Larroquette Show," are given additional showcases tonight in hopes of making that "Super Sunday" investment pay off. If the ratings tonight are low, however, NBC will remember this particular evening as "Terrible Tuesday."
* "The Good Life" (8 p.m.-9 p.m., WMAR, Channel 2) -- Of the two first-run episodes shown tonight, the first focuses on John (John Caponera), Drew (Drew Carey) and the guys, while the second focuses on John's wife Maureen (Eve Gordon) and her career as a theatrical director. NBC.
* "The John Larroquette Show" (9 p.m.-9:30 p.m., WMAR, Channel 2) -- NBC has a first-run episode ready to go with this show as well. This deals with all the strange folks who wander into the bus station at night, and sounds like a variation on the "Barney Miller" theme (which sounds good). NBC.
* "Cries Unheard: The Donna Yaklich Story" (9 p.m.-11 p.m., WBAL, Channel 11) -- It seems like only yesterday that TV presented a docudrama about a woman who was convicted of having her abusive husband murdered. Hey -- it was only yesterday. But that one was on ABC, starring Jennie Garth, and this one is on CBS, starring Jaclyn Smith. It opens with the murder, then slides into a movie-length flashback. My advice: "Cries Unheard" should be Telemovie Unwatched. CBS.
* "NYPD Blue" (10 p.m.-11 p.m., WJZ, Channel 13) -- A repeat episode, but one guest-starring Wendie Malick of "Dream On," who's getting a lot of good guest work this season. ABC.
* "Frontline: 'The Diamond Empire' " (10 p.m.-11
p.m., WMPT, Channel 22 and Channel 67) -- If you want to nibble on a bunch of karats, try this: It's a documentary that lays claim to a gem of a story. Specifically, it's an analysis of a cartel -- a particular family in South Africa -- that controls not only the price of diamonds, but the supply. According to this "Frontline," diamonds are not as rare as most of us think, but instead are surprisingly plentiful. PBS.
* "Late Show With David Letterman" (11:35 p.m.-12:35 a.m., WNUV, Channel 54) -- Crossing enemy lines to visit an old friend, Tom Brokaw is scheduled to be among Mr. Letterman's guests tonight. CBS.
* "Biography: 'Michael Caine' " (8 p.m.-9 p.m., A&E) -- Already the subject of a Cinemax interview and tribute, Mr. Caine now gets the A&E treatment.
