Marathons. "A Christmas Story" (1983), the dark and witty recollection of a 1940s holiday continues its 24-hour marathon on TBS; that's every two hours, with the final one at 4 p.m. The animated "Ice Age 2: Meltdown" (2006) pauses briefly for infomercials, then continues every two hours on FX, from 7 a.m. to 7 p.m.
