Ah, the memories. Sitting down with the family on Sunday evening while Ed Sullivan trotted out the latest "innn-CREDible, simmm-ply FABulous" entertainment. Even if Ed wasn't a staple of your childhood (like, if you weren't even born yet!), tonight you can get a feel for what it was like with the encore airing of the great 1991 "Very Best of . . ." show.
* "Diagnosis Murder" (8 p.m.-9 p.m., WJZ, Channel 13) -- In the conclusion of the repeat that began last week, Dr. Sloan (Dick Van Dyke) is targeted for death after coming up with the evidence that has cleared a plastic surgeon's widow (Dyan Cannon) of killing her husband. (Part 2 of 2.) CBS.
* "Tales from the Crypt" (8 p.m.-9 p.m.), WBFF, Channel 45) -- Two comedy stars match talents in the first half-hour, as Rita Rudner and Richard Lewis appear in the story of a comic-book artist mysteriously immersed in a parallel world. The second half-hour is about a woman who soon regrets trying to end her marriage to a tycoon. Fox.
* "Boy Meets World" (8:30 p.m.-9 p.m., WMAR, Channel 2) -- Cory (Ben Savage) and Shawn (Rider Strong) agree to coach Frankie (Ethan Suplee) on how to win the girl of his dreams, completely oblivious to the fact that the young lady (Mathea Webb) already has a boyfriend: The dreaded Harley (Danny McNulty). ABC.
* "The Very Best of the Ed Sullivan Show - II" (9 p.m.-11 p.m.) -- In this encore of a 1991 special, host Burt Reynolds presents memorable clips from the long-running variety program (1948-71). Acts include the Beatles, Elvis Presley and the Italian mouse puppet Topo Gigio. Also shown is the only existing tape of Richard Burton and Julie Andrews in "Camelot." CBS.
* "The X-Files" (9 p.m.-10 p.m., WBFF, Channel 45) -- Occult practices fuel this repeat, as Mulder (David Duchovny) and Scully (Gilian Anderson) travel to New Hampshire to investigate a youth's slaying. There, the evidence they uncover hints strongly at black magic being practiced in the area . . . and they could become the next victims. Fox.
* "Homicide: Life on the Street" (10 p.m.-11 p.m., WBAL, Channel 11) -- As one might expect, a repeat of this show's Christmas episode from last year has a darker tone than that of most other series at that time of year. The death of a Santa impersonator puts Munch (Richard Belzer) and Bolander (Ned Beatty) on the BTC case, while Felton (Daniel Baldwin) still hopes to see his children -- spirited away by their mother -- on Christmas. NBC.
* "Quick" (8 p.m.-10 p.m., HBO) -- Teri Polo ("Northern Exposure") stars in this 1993 action-adventure tale as a professional killer whose latest assignment -- to kill an accountant (Martin Donovan) -- goes awry, forcing her to go on the run with her would-be target. In hot pursuit are both sides of the law, ranging from the FBI to underworld figures. 8 p.m. HBO.
