David Letterman, shortly after he began as host of NBC's "Late Night," remarked in an interview that he wouldn't feel at all successful until he celebrated that show's fifth anniversary. He achieved that goal, then doubled it and then some, before switching to CBS and "Late Show." Tonight marks the first anniversary of that late-night triumph -- and it's a party well worth watching.
* "TV Nation" (8-9 p.m., WMAR, Channel 2) -- Michael Moore goes to corporate consultants in hopes of getting advice on downsizing his staff -- a funny idea in itself, since Mr. Moore's guerrilla TV outfit already is so lean that he has fewer producers than most shows have caterers. The sole bright highlight of broadcast TV's dull summer continues. NBC.
* "South Central" (8-8:30 p.m., WBFF, Channel 45) -- This is the final repeat showing of this Fox series, which bows out with an episode showcasing CCH Pounder as Dr. LeBrock. Fox repeat.
* "The John Larroquette Show" (9-9:30 p.m., WMAR, Channel 2) -- Speaking of repeats, here's a replay of the first "John Larroquette Show" -- the one to catch if you've decided to watch the show beginning next month, in its new second-season time slot. NBC repeat.
* "Late Show With David Letterman" (11:35 p.m.-12:35 a.m., WBAL, Channel 11) -- Given all the jokes Mr. Letterman makes about the giant rats in the Ed Sullivan Theater, it's fitting he is marking his first anniversary by presenting the Black Crowes. CBS.
* "Your Cheatin' Heart" (8:05-10:05 p.m., TBS) --In this 1964 movie, country star Hank Williams is played by George Hamilton. Scary as it sounds.
* "The Nixon Interviews With David Frost" (9:05-10:40 p.m., DIS) -- Part 5 of 5. Domestic policies and politics, including that infernal Watergate, are the focus of tonight's concluding installment of this repeat showing (followed by formerly unseen outtakes) of Mr. Frost's 1977 syndicated interviewed with Richard Nixon.
* "Bloodfist V: Human Target" (9:30-10:55 p.m., MAX) -- Let's see. Five Bloodfingers, put together, make a Bloodfist -- so what do five "Bloodfist" movies make? A big mess. And enough money to have justified all those sorry sequels.
