Guest stars from familiar places provide the interest in a number of repeats tonight. In addition, CBS News returns to the scene of one its early triumphs to update conditions among migrant workers in America.
* "Mad About You" (8 p.m.-8:30 p.m., WBAL, Channel 11) -- If the agent for animal actors in this repeat seems familiar, think "android" -- it's Brent Spiner, Commander Data of "Star Trek: The Next Generation." In the episode, Paul (Paul Reiser) puts his dog, Murray, into a commercial. Look for Jay Leno and Rachel Hunter in cameo appearances, too. NBC.
ZTC * "Martin" (8 p.m.-8:30 p.m., WBFF, Channel 45) -- If the ex-con who wants to meet with Martin (Martin Lawrence) looks familiar in this repeat, think "Diff'rent Strokes" -- it's Gary Coleman, who played Arnold on the late-1970s sitcom and went on to tabloid fame for suing his parents for allegedly stealing his profits. Fox.
* "CBS Reports: Legacy of Shame" (9 p.m.-10 p.m., WJZ, Channel 13) -- Thirty-five years after a landmark Edward R. Murrow report, "Harvest of Shame," Dan Rather and Randall Pinkston offer an update of conditions for migrant farm workers in America. They're still not so good. CBS.
* "Friends" (9:30 p.m.-10 p.m., WBAL, Channel 11) -- And if Rachel's (Jennifer Aniston) ex-best friend looks familiar in this repeat, think "Dirty Dancing" -- it's Jennifer Grey, who starred in the (1987) hit film. In the episode, she returns to ask Rachel to be her maid of honor in her marriage -- to Rachel's former fiance. NBC.
* "48 Hours" (10 p.m.-11 p.m., WJZ, Channel 13) -- In the first part of a two-subject show, correspondent Erin Moriarty interviews O. J. Simpson's attorney, Johnnie Cochran, about whether his client will be taking the stand. And in the second, the show repeats a 1994 segment on how Americans are fighting fat. CBS.
* "Our Favorite Movies: Mommie Dearest" (9 p.m.-midnight, TNT) -- Sitcom star Brett Butler ("Grace Under Fire") dresses up in appropriate period garb for her presentation of the 1981 film, in which Faye Dunaway portrays an abusive Joan Crawford.
* "Weekend at Bernie's" (9 p.m.-11 p.m., USA) -- OK, it's ghoulish and the humor is adolescent. But the 1989 hit featuring a remarkably agile corpse (Terry Kiser) offers some hilarious moments. Jonathan Silverman and Andrew McCarthy play young executives who find their boss murdered and decide to cover up the case by pretending he's still alive.
