It's a night of firsts: "Baywatch," "The John Larroquette Show" and "Saturday Night Live" offer season premieres, and two new hTC series also make their debut, including "Baywatch Nights" in syndication and "The Home Court" on NBC.
*"Baywatch" (6 p.m.-7 p.m., WNUV, Channel 54) -- As Maxwell Smart used to say, would you believe this is the world's most popular television show? The syndicated series about lifeguards in California -- sometimes called "Babewatch" or "Bodywatch" -- is seen in more than 100 countries and launches a new season with David Hasselhoff continuing as beach boss.
*"Baywatch Nights" (7 p.m.-8 p.m., WBAL, Channel 11) -- And then there were two. This spinoff features the established characters of Mitch and Garner (David Hasselhoff and Greg Alan Williams), who take a moonlighting job as private investigators. Both will still appear on "Baywatch," but on the spinoff they work with another sleuth (Angie Harmon) and have a young assistant (Lisa Stahl). Singer Lou Rawls is also a regular as owner of a nightclub located under their office.
* "Dr. Quinn, Medicine Woman" (8 p.m.-9 p.m., WJZ, Channel 13) -- The earliest days of baseball are evoked as Dr. Mike (Jane Seymour) and her friends take on a traveling all-star team to raise funds for civic improvements. CBS.
* "The Home Court" (9:30 p.m.-10 p.m., WBAL, Channel 11) -- She was good on "Grand" and great before that on the HBO political series "Tanner '88." Now Pamela Reed gets to carry her own show, a comedy in which she plays a judge and single mother. A tough case tonight: Her son (Breckin Meyer) wants to drop out of college. NBC.
* "Saturday Night Live" (11:30 p.m.-1 a.m., WBAL, Channel 11) -- The Artist Formerly Known As Prince, previously announced as musical guest for the 21st season premiere, is a no-show, replaced earlier this week by the band Blues Traveler. But Mariel Hemingway remains as guest host, and the show trots out a number of new cast members: Darrell Hammond, Nancy Walls, David Koechner, Cheri Oteri and Will Ferrell. Norm MacDonald, Mark McKinney, David Spade and Molly Shannon return from last season. NBC.
* "Biography: This Week" (8 p.m.-9 p.m., A&E; Network) -- This new fall series of profiles, timelier than those in the weekday edition of "Biography," has picked the timeliest subject going: O. J. Simpson. The network says the show has gone back to find rare footage of the football player in the 1960s and '70s to tell his complete life story.
