Let's see: "Matlock" sends an attractive assistant to crack a murder case at a dating service, the cops of "New York Undercover" pose as video producers to crack a murder case in the porno industry, and even "Maigret" -- on PBS' "Mystery!" -- investigates the murder of a nightclub dancer. Could it be . . . Satan? Or is it . . . sweeps month? Either way, there are other alternatives.
* "My So-Called Life" (8 p.m.-9 p.m., Channel 13) -- This is one show not to miss, even though most of America, judging from the ratings, fails to agree with that assessment. But tonight's episode not only positively nails high school relationships and insecurities, it does a great job showing how those same teen feelings are percolating, and sometimes raging, in their parents. All that, and Buffalo Tom, too. ABC.
* "Seinfeld" (9 p.m.-10 p.m., Channel 2) -- Two episodes are on tap tonight. The first is an original, in which George (Jason Alexander) becomes obsessed with a used car he thinks was once owned by Jon Voight. The second is a classic "Seinfeld" repeat, in which Jerry (Jerry Seinfeld) can't remember the name of the woman he's dating (Susan Walters) -- except for the clue that it rhymes with a female body part. Also worth noting is that NBC has come up with an audacious new name for this repeat showing: a "bonus episode." In most cases, though, there's a thin line between bonus and bogus. NBC.
* "Scarlett" (9 p.m.-11 p.m., Channel 11) -- Part 4 of 4. No, tomorrow is not another day: This is the conclusion of the eight-hour "Scarlett" miniseries and the portion that departs the most from the original book. Perhaps not coincidentally, it's also the most dramatic segment of the four, and gives both Joanne Whalley-Kilmer and Timothy Dalton their best material. CBS.
* "ER" (10 p.m.-11 p.m., Channel 2) -- Had this episode been televised next Thursday instead of tonight, it'd be right on the money time-wise: It takes place on Thanksgiving. But since it's pre-empted next week, this is the best time for "ER" to talk turkey. NBC.

* "Biography: Donald Trump" (8 p.m.-9 p.m., A&E;) -- Yeah, like here's a guy who needs more publicity. Where I go, you go; where Mr. Trump goes, ego.
* "The Infamous Dorothy Parker" (9 p.m.-10 p.m., A&E;) -- It's a little sad that it took a movie (the soon-to-be-released "Mrs. Parker and the Vicious Circle") to spark a full-blown look at one of the Algonquin Round Table's sharpest wits, but here it is.
