It's not exactly "Who killed Laura Palmer?," but tonight on "Models Inc." is the episode answering the question, "Who killed Teri Spencer?" Considering the viewership of this Fox series, though, the question more people may be pondering is, "Who IS Teri Spencer?"
* "Models Inc." (9-10 p.m., WBFF, Channel 45) -- This may not be a killer of an episode, but at least it's got a killer in it -- and this week, he or she targets another victim. Fox.
* "Turning Point." (10-11 p.m., WJZ, Channel 13) -- Correspondent Don Kladstrup goes back over somewhat familiar territory -- the civil-rights murder case dramatized in the movie "Mississippi Burning" -- but in a thorough, dramatic manner, with fresh interviews and, impressively, some fresh information. This is one "Turning Point" about an event that actually WAS a turning point. ABC.
* "Night of 100 Elvises." (8:05 p.m.-4:05 a.m., TBS) -- Actually, I think the proper plural should be "Elvii." At any rate, this is TBS's umbrella title for a night's worth of Elvis movies, with a gaggle of Elvis impersonators as hosts. The Elvii in "Blue Hawaii" (8:05 p.m.), "Fun in Acapulco" (10:05 p.m.), "Girls! Girls! Girls!" (12:05 a.m.) and "Paradise, Hawaiian Style" (2:05 a.m.) are real; the others are mere imitations.
* "The Odd Couple." (9-11:25 p.m., TNT) -- This installment of TNT's "Our Favorite Movies" presents "The Odd Couple," starring Walter Matthau and Jack Lemmon -- with Jack Klugman and Tony Randall as hosts. Question: When you add two odd couples together, does that make them even?
* "Dream On." (10-10:30 p.m., HBO) -- Two weeks ago, Martin's ex-wife Judith brought a manuscript for Martin's boss to publish; this week it's Martin's son Jeremy, played by Chris Demetral.
* "The Larry Sanders Show." (10:30-11 p.m., HBO) -- After clocking four laugh-out-loud chuckles in the first five minutes, I realized, once again, just how sharp and funny this series is. This week it's a turn for more of the supporting characters to shine -- chiefly Wallace Langham as Phil, who gets promoted to head writer. Rip Torn, as Artie, makes every line sing, and he's got a lot of great ones this time. Just like the last two week's shows, this episode of "Sanders" is hilarious. This show is on quite a roll.
