FRIDAY Tom & Jerry's 50th Birthday Bash (TBS, 8:05-9:05 p.m.): Is it really half a century now that they've been chasing across animated screens, this ageless cat and mouse? To salute the still-popular cartoon characters, the catchy special builds a little story around a security guard (played by John Goodman) who stumbles upon a vault of Tom & Jerry films. SUNDAY Decoration Day (NBC, 9-11p.m.): Even in 1975 and even as a matter of principle, Georgia was not the place for a black man to turn down the Congressional medal of Honor. The act of defiance makes waves in this drama of values, but his cause is championed by a boyhood friend, now a retired judge, played by James Garner. Based on the John William Corrington nouvella, the tale launches the Hallmark Hall of Fame's new season.
MONDAY The Divine Garbo (TNT, 8-9 p.m.): Glenn Close hosts and narrates a tribute to the women whose face is our culture's most enduring image of classic beauty: the late film star Greta Garbo. As these stills and rare early footage suggest, her appeal had a lot to do with a mystery and a tragic dimension unduplicated since then.
Fifteen Years of MacNeil/Lehrer (PBS, 8-9:30 p.m.): MacNeil and Lehrer have to answer questions for a change, as two regulars on the ``NewsHour'' - David Gergen and Mark Shields - turn the tables on them to get answers about the thoughtful and highly durable show. The talk is aided by clips of events culled from over the years.
