The Fab Five return with nine new episodes beginning with tonight’s “Queer Eye for the Straight Guy” (9 p.m., Bravo). This new season of the most talked-about makeover series of all time will feature a new motley crew of style-challenged heterosexuals, including Olympic figure skater John Zimmerman (March 9).

Other upcoming fashion-free fellas: Ralph, a radio-show host and DJ in dire need of an updated look; Kevin, a stand-up comic with obsessive-compulsive disorder who still manages to be a slob; and Mark, who thinks maybe it’s time to depart with his 10-year-old mullet, muttonchops and handlebar mustache.

Who knew “That Girl” could be so judicial? Marlo Thomas appears on “Law & Order: Special Victims Unit” (9 p.m., NBC) in the first of five episodes as a former judge-turned-consultant. Dixie Carter (“Designing Women”) also guest stars as attorney Denise Brockmorton.

No puppeteers better captured the psychedelic excesses of the early 1970s than Sid and Marty Krofft. TVLand offers a four-hour marathon of Krofft creations, including “Sigmund and the Sea Monsters” (7 p.m.), “Electra Woman and Dyna Girl” (7:30 p.m.), “Lidsville” (8 p.m.), “The Bugaloos” (8:30 p.m.), “H.R. Puffnstuf” (9 p.m.) and more. This is not for the weak of stomach.

The Day-Glo shebang concludes with “The World of Sid & Marty Krofft, Live at the Hollywood Bowl” (10 p.m.) featuring musical performances by Johnny Whitaker, Jack Wild and the kids from “The Brady Bunch.” It must look like a lunchbox come to life.
