* Is actor Ray Sharkey really the sitcom Dad type? He is an interesting actor, but is undoubtably most memorable as mobster Sonny Steelgrave in a "Wiseguy" sequence a few seasons ago and as mobster Bugsy Siegel in a made-for-cable movie last year.
Regardless, ABC tonight premieres a summer tryout series, "The Man in the Family" (at 9:30, Channel 13), in which Sharkey plays a disreputable son who takes over the family grocery -- and the family, too -- when his father dies. The series is not on ABC's fall schedule, but will have a seven-week run to show its potential as a mid-season replacement.
* To be or not to be (a Klingon)? Last season it was Capt. Picard (Patrick Stewart) who was transformed into an evil half-machine, half-alien in the final spring episode of "Star Trek: The Next Generation." We didn't learn until fall whether he would escape the clutches of The Borg. This year, Klingon security officer Worf (Michael Dorn) is the central figure in the season-ending cliff hanger (at 9 tonight, Channel 45). The Romulans and Klingons are restive, and Worf must choose between allegiance to his home planet or the Federation he serves.
* Does TV ever sound better than when simulcast on radio? Note that tonight's "Metropolitan Opera Presents," a three-hour performance of Mozart's "The Magic Flute" (at 8, channels 22, 26 and 67), can also be heard on WBJC-FM 91.5.
* Who says business is boring? The daily American Public Radio series "Marketplace," heard at 6:30 p.m. in Baltimore on WJHU-FM 88.1, is tackling a fascinating topic with both economic and sociological implications in a special two-part series this week.
"How Much Is Enough?" is the question asked by the report, airing tomorrow and Friday. Host/producer David Freudberg calls the series "first person chronicles of the '80s," and the show examines the trend in which some successful individuals are now down-scaling their lives in search of simplicity.
* Is anybody else ready to hustle out to the nearest travel agency for tickets to the Bahamas? Those lushly evocative musical ads for the island paradise, now running all over the tube, are the prettiest piece of video work we've seen since those Asia-oriented airline spots a few years ago using Gershwin's "Rhapsody in Blue."
* Were you really paying attention to the answers to yesterday's trivia quiz in this space regarding the series "Head of the Class?" Momentarily, at least, Media Monitor apparently was not.
We listed the 1969-71 NBC series "The Bill Cosby Show" as a notable school-based series of the past, and in some editions mis-identified Cosby's character as coach/teacher Cliff Kincaid. Well, he was Mr. Kincaid, but his first name was Chet. (Obviously, we flashed forward to Cliff Huxtable, Cosby's current name on "The Cosby Show.")
