The Kings of Comedy and the Blue Collar Comedy team have long existed in parallel dimensions, carving out their respective niche of the nightclub and TV audiences. Both groups had their stint on the departing WB network. Steve Harvey, Jamie Foxx and Cedric the Entertainer were part of the network’s early years, while the Blue Collar troupe appeared during the WB’s final seasons.

Now, like Cedric the Entertainer, “Blue Collar” star Jeff Foxworthy takes a stab at the variety show with “Foxworthy’s Big Night Out” (7:30 p.m., CMT).

Also like Cedric, Foxworthy has his own stable of sexy dancers (“The Homewreckers”) to accompany the songs, skits and standup. While Cedric’s musical efforts echoed Barry White, Foxworthy seems determined to fill the entertainment void created by the departure of “Hee Haw.”

Foxworthy’s standup material is more gentle than “Blue.” He sets the tone during his first monologue when he begins almost every joke with the phrase, “My wife :” His mother is also in the audience.

The skits are much looser, occasionally bawdier and are, for the most part, mercifully brief.

¢ The new PBS series “AIR: America’s Investigative Reports” (8 p.m., PBS) profiles journalists as they dig into important stories. Tonight’s feature celebrates the work of a team from the South Florida Sun-Sentinel who uncovered mismanagement, arrogance and incompetence in FEMA and its director, Michael Brown, in a series of 2004 stories. Yes, these stories emerged a full year before Hurricane Katrina.

¢ In other journalism news, CBS will repeat “Dan Rather: A Reporter Remembers” (8 p.m., CBS), which originally aired in March after Rather left his anchor job. He has since left the network.

“Today Show” co-host Katie Couric will assume anchor duties for the network Tuesday. Couric’s immediate predecessor, Bob Schieffer, deserves praise for his 18-month tenure. The veteran newsman had an assuring avuncular authority blessedly free of celebrity overtones. And he increased the audience for the newscast.

¢ The Encore network will celebrate Labor Day weekend with its second annual “Big ’80s Weekend.” In addition to 80 hours of movies from the shoulder-pad decade, the “Big ’80s Weekend” will feature performances from the infamous Viper Room on the Sunset Strip from former members of such never-to-be-forgotten bands as the Go-Go’s, the Motels, Tommy Tutone and Naked Eyes.
