Dec. 10: Yikes, this has trouble written all over it: On Supernatural, Dean (Jensen Ackles) considers a deal in which he would act as the Grim Reaper for 24 hours in exchange for Sam's (Jared Padalecki) soul. 9 p.m., The CW.
Dec. 11: After all these years, Frosty the Snowman remains oh so cool. Why? Because he really knows how to rock a corncob pipe and button nose. Frosty Returns immediately follows. 8 and 8:30 p.m., CBS.
Dec. 12: This season of Dexter started awkwardly, with the serial killer mourning the death of his wife at the hands of another serial killer. But then the show got an injection of two things that will perk up any series: a new cohort (Julia Stiles, check) and a new nemesis (Peter Weller as an oh-so-sleazy cop). This is the season finale, and the odds are against everyone getting out alive. 9 p.m., Showtime.
Dec. 12: Not up for Dexter's darkness? How about another look at the 1954 holiday classic White Christmas, starring Bing Crosby, Danny Kaye and Kentucky's own girl singer, Rosemary Clooney? 8 p.m., AMC.
