In the television equivalent of pre-gaming, TNT will be airing 20 episodes of Supernatural starting at midnight Sept. 24 (Thursday going into Friday) as a warm up to the show's sixth (!) season premiere. The marathon will run until 8 p.m. ET, giving you one hour to eat, catch a cat nap, and/or shower, all of which you likely will not have done in the last 20 hours.
As a proponent of proper season premiere planning, I'm on board! I even like the lineup; it gives me one hour of sleep before work (5 a.m. to 6 a.m., not my favorite episode), commute time (Yay for at-desk TVs!), and the aforementioned hour to get home and prepare for amazingness on the CW.
