Marathons aplenty: You can watch "The Golden Girls" (starting at 7 a.m. on the Hallmark Channel), "Ghost Hunters" (7 a.m. on SyFy), "Dirty Jobs" (8 a.m. on Discovery) and "16 and Pregnant" (10 a.m., MTV). Since it's LABOR Day, MTV might be the most appropriate.

"Dinosaur Train" (8 a.m., WTTW-Channel 11): Yet another marathon. Plunk the kids in front of the television to introduce them to Buddy, a curious T. Rex, and his adoptive Pteranodon family. Will he grow horns? Will he realize that steam engines haven't been invented yet?

"The Last Truck: Closing of a GM Plant" (8 p.m., HBO): Fired workers reminisce about when people used to buy cars.
