A lot of unusual stuff is appearing on TV tonight. Comedians guest-star as homeless people on two CBS sitcoms, while a CBS series canceled after a single outing returns, with a handful of never-seen episodes, on VH1.
* "White Christmas" (8:30-11 p.m., Channel 2) -- Bing Crosby and Danny Kaye star with "sister act" Rosemary Clooney and Vera-Ellen in this 1954 classic, a distant echo of the movie "Holiday Inn," which in 1942 featured Irving Berlin's song "White Christmas." The patter is witty, the dance numbers are glamorous and rich with color, and the big show the boys put together for their old general just might bring a tear to your eye. OK, it's sappy, but that's part of the fun. NBC.
* "Dave's World" (8:30-9 p.m., Channel 11) -- Tonight's plot involves a former competitor of Dave's who has fallen on hard times and is now living on the street. He's played by comedian Bobcat Goldthwait. CBS.
* "Murphy Brown" (9-10 p.m., Channel 11) -- There are times when a cameo appearance by someone is sufficient reason to watch a show, and tonight's "Murphy Brown" is a good example. There's a fleeting appearance by Bob Keeshan, still better-known, after all these years, as Captain Kangaroo. CBS.
* "Love & War" (9:30-10 p.m., Channel 9) -- Here's the other homeless man story (but it's blocked out on Channel 11 by another "Murphy Brown" episode). This one is played by Brian Doyle-Murray, who sues the Blue Shamrock. CBS.
* "Emily Bronte's Wuthering Heights" (8-10:30 p.m., TNT) -- This British film features "Quiz Show" star Ralph Fiennes as a long-haired Heathcliff, and this role contributed to his being cast "Schindler's List." Juliette Binoche, who plays Cathy, hasn't gotten as big a break in the intervening years, but this TNT premiere does feature some terrific English scenery -- moors or less.
* "South of Sunset" (10:30-11 p.m., VH1) -- This 1993 CBS action series, starring Glenn Frey as a Los Angeles private investigator, was shown once and yanked from the schedule, never to return. As part of its Eagles celebration, VH1 excavates and presents five "new" episodes of the series, with one episode shown each weeknight.
