Go ahead and sing along if you know the words to this holiday classic: "People bleedin' when they open fire, Uma shootin' off your nose...." Nobody? Huh. Well, nonetheless, from noon to midnight ET on Dec. 25, Encore will broadcast A Very Quentin Christmas, a veritable orgy of auteur Tarantino's five flicks airing back-to-back for the first time, unedited and commercial-free. Even weirder, the marathon is being hosted by an eggnog-swilling Michael Madsen. I'm sorry, but I just can't see him remaining conscious past the 4:40 pm showing of Jackie Brown.
