TELEVISION - Sept. 8, 1992

The Moore, the Mary-ier: Here’s a VCR alert for Mary Tyler Moore fans. Nick at Night is preempting all regular programming for a week starting this weekend to present a “Mary-thon”--seven consecutive nights of “The Mary Tyler Moore Show.” Each night will be devoted to a particular season, and among the nuggets on the schedule is the award-winning “Chuckles Bites the Dust” episode that will turn up Sept. 17 at 8 p.m. Following Saturday’s kickoff (10 p.m. until 6 a.m. Sunday), the shows will start nightly at 8 and run until 6 the next morning. The Mary-thon is hyping the fact that MTM’s show is joining Nick’s lineup on Sept. 19 (weeknights at 9, weekends at 11 p.m.).
