Baltimore man-about-town Steve Geppi gets a moment in the national spotlight on cable tonight. From tiny comic books do mighty empires grow.
* "The Cosby Show" (5 p.m.-5:30 p.m., WNUV, Channel 54) -- It ain't "I Spy," but it's as close as you'll get these days: Robert Culp, Bill Cosby's fellow spy from 1965 to 1968, shows up as the Huxtables' dinner host.
* "Before They Were Stars" (8:30 p.m.-9 p.m., WMAR, Channel 2) -- See David Letterman during his days as an Indiana weatherman, where he probably predicted hail the size of canned hams. ABC.
* "The Single Guy" (8:30 p.m.-9 p.m., WBAL, Channel 11) -- Julia Louis-Dreyfus stops by in this repeat as Jonathan's girlfriend, who gets a little bent out of shape when they get held up at gunpoint. I wonder if Elaine would have acted the same way? NBC.
* "Coach" (11:30 p.m.-midnight, WBFF, Channel 45) -- Enjoy one of the best episodes of this sporadically funny series, as Coach Hayden (Craig T. Nelson) and Christine (Shelley Fabares) try to have their wedding ceremony performed in a decrepit chapel.
* "A Fistful of Dollars" (8:05 p.m.-10:05 p.m.), "For a Few Dollars More" (10:05 p.m.-12:50 a.m.) and "The Good, The Bad and The Ugly" (12:50 a.m.-4:20 a.m., TBS) -- Can you take eight-plus hours of The Man With No Name? Stronger folks than you have died trying. But if you're up for it, you'll enjoy one of the most fulfilling partnerships in screen history: Clint Eastwood and director Sergio Leone.
* "Rediscovering America" (10 p.m.-11 p.m., repeats 2 a.m.-3 a.m., Discovery) -- Benjamin Franklin was the most accomplished American of his age: inventor, printer, writer, patriot, postmaster, diplomat. He even invented the lightning rod. David Hartman is the host for this lively look at an incredible life.
* "Neat Stuff" (10 p.m.-11 p.m., repeats 1 a.m.-2 a.m., The Learning Channel) -- Steve Geppi, Orioles part-owner, Baltimore magazine publisher and comic-book king, is featured on a show about collectors and their collections.
