• For those not compelled to spend the day shopping, the Friday after Thanksgiving can be the most blissfully lazy day of the year. Kind of like New Year’s Day without the bowl games or headaches. And like that celebration of lethargy, there is no shortage of marathons for the passive and couch-bound.

Fans of “General Hospital” and its bad boy character Jason Morgan (Steve Burton) can spend “Black Friday” with a “Black T-shirt Friday” marathon (6 p.m. to 11 p.m., Soapnet) of Morgan-centric episodes.

The ongoing “James Bond” movie marathon on SyFy concludes with “Tomorrow Never Dies” (4:30 p.m.). Discovery chums for viewers with a “Deadliest Catch” marathon (8 a.m., to 7 p.m., Discovery). Fans of “Law & Order: Special Victims Unit” (5 a.m., to 6 p.m., USA) can revel in every grim detail for a whole 14 hours. Catch 10 hours of “Criminal Minds” (2 p.m. to midnight, Ion). Or five hours of “Everybody Loves Raymond” (7 p.m. to midnight, TV Land). If turkey leftovers don’t seem appealing, Food Network offers eight solid hours of “Diners, Drive-ins and Dives” (1 p.m. to 9 p.m., Food). Animal Planet offers a 13-episode marathon of “Life” (4 p.m. to 5 a.m., Animal Planet). Looking for five hours of “Golden Girls” (7 p.m. to midnight, WE)? Spike presents six consecutive episodes of “1000 Ways to Die” (6:36 p.m., Spike). You do the math.

• The new series “Spy Wars” (9 p.m., Science) introduces viewers to members of the intelligence community from all over the world, including undercover agents who have served from Cuba to China, as well as those who have served as double agents here at home.

• The gang plots revenge for a fixed karaoke competition on the movie-length helping of “Victorious” (7 p.m., Nickelodeon), “Freak the Freak Out.”
